Loud Boom in Calgary Remains Unexplained (Mar 4)

A loud explosion that rocked homes in northwest Calgary around 5:00 pm Tuesday remains a mystery.

Emergency services were slammed with phone calls about a loud boom heard and felt across the region, but multiple firefighters and cops scouring more than half a dozen neighbourhoods couldn't find any evidence of an explosion.

After an hour or so of searching the communities of Hidden Valley, Tuscany, Evanston, Nose Valley, Ranchlands, Edgemont and Silver Springs, firefighters and cops gave up the search for an answer.

"We can't have rigs out in these temperatures for hours on end ... (that's) just not a prudent use of resources," fire battalion chief Allan Ball said.

"We don't even know where this came from."

An expert with the University of Calgary says that a seismic monitoring station, which could have shed light on the mysterious explosion, was offline at the time.

ENMAX says there were no gas or power outages and Lafarge says crews were not conducting any controlled detonations in gravel pits.

Military aircraft have also been ruled out.

It also wasn’t likely a frost quake, Ball said, though it was considered a possibility at one point during the search.

The strong underground noise woke many Chileans- CHILE

Thursday March 6, 2014

An earthquake of 5.7 degrees shook central Chile
The movement felt this morning in 57 cities. No casualties were reported.

SANTIAGO DE CHILE, Chile -. An earthquake measuring 5.7 degrees on the Richter scale, "with much noise underground" shivered this morning to four regions of central Chile, with no casualties or damage were reported.

According to the National Seismological Centre, University of Chile, the tremor was felt at 01.37 local whose epicenter was 38 miles northwest of Valparaiso and 59.5 kilometers deep.

The earthquake affected regions of Valparaíso, Santiago Metropolitan, O'Higgins and Maule, according to a report from the National Emergency Office (Onemi) under the Chilean Interior Ministry.

The strong underground noise woke many Chileans levantararon thinking about a new earthquake, especially after the series of earthquakes that were felt heavily in central and northern Chile.

About two hours before the earthquake phenomenon, many people were calling local stations denouncing underground noises, but no authority could give explanations.

According to Onemi, the earthquake affected a total of 57 cities and towns with intensities ranging between six and two degrees in international Mercalli scale, ranging from 1 to 12.

Mystery Boom on the Mississippi in Iowa (Mar 10) Viewers on both sides of the river from Davenport to Rock Island have called, emailed and sent Facebook messages to the TV-6 newsroom asking about a mysterious rumbling and loud boom.

"I heard a really loud boom," said Chris Rice.

"I heard a rumble," said Tanisha Douglas.

" I heard a pretty big explosion," said Logan Edwards.

The noise was so loud that many said it caused homes and businesses to shake.

"I expected to see a mushroom cloud when I went out there off in the distance," said Rice.

Contacted were the police and fire departments, the airport, the Rock Island Arsenal and even a meteorologist about what it could be, but no one knows.

"I haven't heard anything that loud since leaving Iraq in 2007," said Edwards.

"It sounded like something really big on the street. Like something rolling by on the street and then there was a rumble, too," said Douglas

Whether the noise was a rumble, explosion or boom, some of you tell us, this isn't the first time you've heard it.

"On January 14th I heard the sound," said Rice. "I'm used to hearing really loud sounds because I live near the river. I hear trains, barges. I've always lived near the arsenal. I hear all types of sounds, but this one was way louder."

The mystery remains unsolved....

Mysterious Booms Worry Central Florida Residents (Mar 19)
Many people in central Florida have been hearing a boom around the same time every night. Not even the Osceola County Sheriff’s Office has an answer.

“It was like a ‘BOOM!’ Then, the windows kinda shook,” said Kissimmee resident Daryl Mercado.

People in Kissimmee, St. Cloud and even as far away as Haines City in Polk County have reported hearing these mysterious booms.

They start around 10 p.m. and they like thunder. Mercado said he’s heard them over the past three weeks.

He was studying the second time it happened, but he grabbed his flashlight to see what it was.

Mercado isn’t the only one puzzled by this. We reached out to the Osceola County Sheriff’s Office, but a spokesperson said they don’t have any answers either.

Mystery Boom Rattles Southwest Oklahoma (Mar 26)

Just after 6:00 p.m. Wednesday, residents were rattled after hearing what sounded like a large explosion nearby. 24 hours later, residents and officials alike are still stumped, which has caused the mystery blast to be the talk of the town.

In southwest Oklahoma, many of us are used to the rolling thunder, or even Fort Sill's artillery popping. But what Stephens County experienced Wednesday night was something different.

"I asked my husband, I was like, 'what was that?' he said I think it was thunder and I said 'no I don't think so!'," said one Duncan resident.

The boom was so loud, those who heard it weren't the only ones shaken by its power.

"I know it hit pretty hard though, because it shook the stuff in my house," said another Duncan dweller.

"I actually wanted to run out of the house because it shook the house," said one worried Duncan resident.

It was enough to grab the attention of the Duncan Police Department and the Stephens County Sheriff's Office. Sheriff Wayne McKinney says this event isn't entirely uncommon.

"Over the past year, we've had calls out in the county where people have heard explosions or what they thought was explosions," said Sheriff McKinney.

Over the past twenty-four hours, the boom was reported in Bray, Duncan, Marlow, even Cotton and Tillman counties.

Carrie Kirkpatrick is investigating the mystery explosions being heard in Highgate. Picture: Nigel Sutton

Friday, April 4, 2014 
5:43 PM

Mysterious “explosions” causing houses to shake in Highgate have become the focus of a police investigation.

Several people living in Priory Gardens said they regularly hear deep booms that have been likened to the sound of a gas explosion.

The noise is so loud that many say it causes their houses to shake in their foundations.

TV producer Carrie Kirkpatrick, said: “It’s just so mysterious. Sometimes it’s more than once a week and then you don’t hear it for a while.

“Friday night seems to be most popular. It can be at any time between 10pm and midnight.

“I’m still awake at that time, and my eight-year-old says, ‘I wish the loud bangs would stop’.”

The mother-of-one has reported the noises, which were first heard 18 months ago, to police and Haringey Council.

Both were unable to identify where the sounds might be coming from and will continue investigations into the cause of the explosive booms. Residents in Wellfield Road, Muswell Hill, have also reported hearing the noises.

Those who have heard the explosions have also reported seeing flashes in the sky, but they don’t believe the noises could be from fireworks.

Some suggested the sounds may be caused by excavation work at Shepherd’s Hill allotment.

But the team in charge of the green space said no excavation work has taken place at the times people have reported hearing the noises.

An electrical substation in Shepherd’s Hill has also been considered as a possible source of the bangs. Others have come up with more inventive explanations.

“Some people have asked, could it be fracking or military manoeuvres?” Ms Kirkpatrick said. “It’s Highgate, it’s not military manoeuvres.

“They said it could be the Underground, but they wouldn’t be doing explosive work at night without telling us.

“Some of my friends are suggesting it is a paranormal occurrence. I think we need to stalk out the woods at night.”

Cllr Lyn Weber, independent member for Crouch End on Haringey Council, said it was an “intriguing mystery”.

“I wondered whether it was something to do with the big basement works [at Witanhurst house] up in Highgate,” she said.

Residents should report the explosion sounds to Haringey Council’s noise team on 020 8489 0000.

More mystery ‘explosions’ in Highgate baffle experts

Will Wheatcroft heard another loud bang on Monday night at 10pm. Picture: Nigel Sutton

Thursday, April 10, 2014 
10:00 AM

Noise experts are scratching their heads over mysterious “explosions” in Highgate – after dozens of residents reported hearing 
another loud bang this week.

People living in the Shepherd’s Hill and Archway Road area of Highgate said they heard a loud explosion noise – similar to a bomb or gas explosion – just 
before 10pm on Monday.

Last week, the Ham&High reported that residents in Highgate have been hearing the loud booming sounds for about 18 months.

Officers from Haringey Council’s noise team are investigating but the local authority has been left baffled by the phenomenon.

Will Wheatcroft, 31, said he heard the latest “very loud explosion” while sitting on the sofa with his fiancée Stephanie in his Stanhope Road home.

“Really it sounded like a car bomb or a gas explosion,” he said. “It made us turn around and say, ‘What the hell was that?’

“I expected to hear sirens a few minutes afterwards, but there weren’t any. After reading the Ham&High, I can now understand why, because it happens a lot.”

Residents in Muswell Hill and Crouch End have also reported hearing the noises, that are said to be so loud they shake the foundations of their homes.

One Twitter user reported hearing another loud bang on Tuesday night at about 10pm in Crouch End. A couple in Priory Gardens, Highgate, have contacted Haringey police about the sounds.

Ruled out

But after a short investigation a spokesman advised residents to alert the council’s noise team 
instead, unless it is an emergency.

The National Grid has ruled out gas explosions in the area while UK Power Networks said the bangs could not be caused by an electrical substation in Shepherd’s Hill Allotments.

The Met Office said there was no thunder or lightning on Monday night and Thames Water said the noises could not be caused by sewer repairs in Langdon Park Road and Northwood Road, Highgate. Haringey Council restricts building works to working hours, TfL is not carrying out explosive works at Highgate Underground station, Archway Road.

Mr Wheatcroft speculated it could be sonic booms caused by aeroplanes breaking the sound barrier. But a spokesman from the Department of Transport said they would be heard across a much larger distance if they were the source.

A council spokesman said it could be “kids with bangers” playing in Queen’s Wood, Muswell Hill, but none of the council’s noise team officers had a probable explanation for the explosions.

The local authority will now work with Haringey police to try and identify their source.

In an online poll, Ham&High website voters thought the noises were most likely caused by a faulty substation or UFOs.

Mystery Booms Heard Across West Central Florida (May 7)

Hundreds of people across the Bay area say they got a scary wake up call this morning.

A series of loud booms heard across Tampa Bay and parts of Lakeland today is confounding law enforcement officials.

Many say they woke up to shaking windows and a loud noise, but no one knows what caused it.

“The house literally shook, said Polk County resident,” Arlene Sambursky

Others heard it and called 911. Some even called the fire department.

“We heard this big big bang!,” said one 911 caller.

“The only way I can describe it is two loud tremors," a 911 caller told an operator.

The noise was so loud people from Polk to Pasco County dialed 911 to report the suspicious, earthshaking wake up call.

Merrill Sambursky was one of those callers.

“I’ve been in a couple earthquakes out in California so when I felt the house shake I said wait you’re not supposed to get earthquakes here but who knows the way everything’s going lately you don’t know,” he said.

General speculation was that the noise came from some kind of military maneuver over the Gulf of Mexico. But officials at MacDill Air Force Base say it wasn't them.

Lt. Patrick Gargan, a spokesman for the 6th Air Mobility Wing at the base, said MacDill has had noise complaints but typically doesn't get calls about booms.

"At this time, we don't know anything about the reported loud noises this morning," he said. "If we hear anything, we'll let you know."

The air force base said they can’t confirm it was caused by a sonic boom.

Sambursky, a retired air force police officer said, “This one this morning was no sonic boom."

Mystery Booms in Michigan (May 8)

(Apparent nexus: Michigan water main break)

Tustin resident Stephanie Yonkman said a very loud noise rattled her house and shook the ground on Thursday.

Massive booms were also heard on and off on Sunday, Yonkman said.

“It was like a huge sonic boom,” she said. “We thought they were blasting dynamite, but we didn't see any reports on it."

Although thunderstorms had been in the area, none were occurring at the time.

Osceola County Undersheriff Justin Halladay said his department received no calls about the noise.

A similar incident occurred in April 2013 in the Harrietta area.

That time, four different callers contacted central dispatch.

The South Branch Township and Harrietta fire departments searched for the source of the noise but were unable to identify a cause.

Because the noise was heard throughout the area, firefighters weren’t certain it originated in Slagle Township.

Sardinia, roars like an explosion off the coast of Gallura is a mystery

http://translate.google.com/translate?hl=en&sl=auto&tl=en&a...

Two explosions, like two loud explosions were felt sharply this morning off the coast of Gallura. The roar that vibrated the windows of the houses were found between 9 and 9:30, at two separate times, and lasted between five and ten seconds. Their cause is still unknown. "I was having breakfast in a bar in Porto Cervo - said a trader - we heard the doors of the bar vibrate as if someone wanted to enter. After a few seconds, and 'heard a second rumble, although more' strange, more 'gloomy. Shortly after we called a friend who lives a couple of miles away who had heard what sounded like two explosions. " The explosions were felt in Golfo Aranci, La Maddalena and even Pertusato in Corsica. Even in the radar towers of the Coast Guard, particularly in La Maddalena, vibrations were felt as though it were an earthquake. But the equipment of the National Institute of Geophysics and Volcanology did not reveal anything, no shock. Discarded at the time, the hypothesis of exercises at sea - none have been reported - or phenomena of "sonic boom" associated with the passage of jet aircraft in transit at low altitude. The military airport of Decimomannu did not detect anything. The two explosions remain a mystery for the moment.

The howling Earth has primarily been reported in N America and from the UK across Europe, locations where the ground is being bent by the N American bow or stretched across Eurasia, a situation that will be relieved when the N Atlantic rips open and the New Madrid adjusts. A search of the Internet for YouTube recordings of the howling Earth show that the pattern of being clustered on the N American continent and in the European stretch zone has continued. London

Unexplained Boom, Flashes of Light Near Great Lakes (May 28)

Numerous reports from local residents seeing a flashing light and hearing a loud sonic boom began running rampant on Orangeville-centric social media sites on Wednesday night (May 28).

Residents in a radius as wide as Howard Crescent near the Headwaters Health Care Centre to College Avenue near Credit Meadows Elementary School reported hearing the unidentified noise at about 9:30 p.m.

“Although I did not see a “flash,” I did hear the very loud sound,” Brett D Hancock posted on Facebook from Murray Court. “And it was extremely loud.”

“By the hospital,” echoed Jada Doucette. “My big bully went ballistic. Even made my daughter and myself jump. It was so loud.”

According to Rob Koekkoek, engineer with Orangeville Hydro, the local utility has no evidence that one of its transformers blew last night. There is no evidence of any field issues either..

“There have been no related calls from our customers,” Koekkoek said in an email. “It appears the noise is not related to our equipment.”

Orangeville police Const. Scott Davis confirmed officers were called to investigate a report of a loud noise and flash of "white light" near Howard Crescent at 9:41 p.m. Responding officers, however, were unable to determine the cause or find any explanation for the apparent phenomena.

“We checked the area. We couldn’t come up with a source for the noise or the white light, and that was it,” Davis said. “That is the only report that we had.”

Jeff Renaud, senior media relations officer at the University of Western Ontario, has passed information about the reports onto scientists at the Centre for Planetary Science & Exploration, which has several highly advanced video surveillance systems set up across the province, including one in Orangeville.

As far as he knows, however, it is not something scientists are investigating right now.

If a meteor were to fall to the ground, Williams suggested the impact would register on seismic detectors. As he noted further, the United States Geological Survey isn’t reporting any significant seismic activity in this region.

So, what actually caused the loud boom, and a flash of light? It’s anybody’s guess at this point.

Mystery bangs and shaking in Auckland - NEW ZEALAND

Last updated 22:19 18/06/2014

http://www.stuff.co.nz/national/10174693/Mystery-bangs-and-shaking-...

18 JUNE 2014. A series of mysterious "explosions" have been reported across west and north Auckland, but police are mystified. Reports of loud ‘‘bangs’’ followed by houses shaking began about 5pm, in the Hibiscus Coast area. Inspector Tony Edwards of police northern communications said police received reports of the bangs from the Herald Island - Greenhithe area about the same time.

More reports came in a while later from the Ranui - Scenic Drive area in West Auckland. A Fire Service worker came in to work later and confirmed they had heard the noises in the Red Beach area, which is on the Hibiscus Coast. Edwards said people had variously described the noises as sounding like gun-shots and loud explosions. Police had checked with the Air Force, which has a base in Whenuapai, but turned out not to be not responsible, and neither was Paremoremo prison.

Lines companies had not reported any electrical disturbances and Geonet is not showing any tectonic activity in the Auckland area. Arkles Bay resident Will Trayes said he heard the noises about 4pm. His house shook with a "sudden, quick vibration" for two or three seconds and he heard a slight rumble similar to thunder. Six or seven minutes later it happened again and then again six or seven minutes after that.

His sister said she thought it was a truck going past the house, he said. ‘‘I wasn't worried, I was just wondering if there was going to be a bigger shake." A local Facebook page was inundated with 450 comments after Kelly de Rooy posted: "Holy hell, was that an earthquake I just felt in Stanmore Bay? My entire house just shook".

Sally Louise Dodsworth wrote: ‘‘3 big shakes here in Stillwater’’ while Deborah Johnston said: ‘‘We heard real weird noise too and the cupboards were vibrating in Red Beach.’’ Kathryn Wales wrote: ‘‘Can anyone see Rangitoto???? THat's not blowing up is it???’’ The noises remain a mystery. Continue...

What is the source of the strange sounds in the sky over Plymouth (UK)?

Plymouth residents are struggling to cope with ‘the hum’ – whatever it may be – and want to source its origins.

People hearing it say they suffer and the high-pitched noise has increased in intensity!

The Plymouth hum seems almost electrical in nature and to reverberate around the walls houses. However, the Council’s Environmental Protection Department was not able to detect anything. AND the noise did not abate.

It seems a particular business on an industrial estate has moved its cooling towers to an area near the front of their building, approximately 400 metres away. But I doubt it could be related to the rumbling sounds.

Other people in Plympton (5.5 miles away) also started hearing the weird metallic noise about five or six weeks ago, but the source is also unknown. Could it be related to the nearby power station?

Mystery Booms Rattle Lima on August 4 2014

Mystery Booms Rattle Lima? A series of loud sounds alarmed citizens of Lima on August 4 2014. But what was their origin?

Suddenly, social media were flooded by reports of loud explosion noises heard in different districts of the vast city of Lima (El Augustino, San Borja, Rimac, La Molina, Surco, Surquillo, Lima Center, San Juan de Lurigancho, Brena, Jesus Maria, Miraflores). Sound of thunder? Dynamite explosions?

• The National Service of Meteorology and Hydrology rules out thunder as no storms were rolling over Lima at this time.
• There wera actually not explosions or any dynamite attacks reported on this day either.

Officials believe the loud and mysterious detonations felt strongly in several districts of metropolitan Lima were the results of fireworks taking place at the Cerro San Cristobal.

Underground Strike worries Hacienda Gardens neighbors (city neighorhood)
Noticias de Querétaro
Friday, August 22, 2014
15:20 (CDT)
BY LUIS MONTES DE OCA
An underground hit, with consequent shaking doors and windows has been recorded in the Hacienda Gardens neighborhood for about four months, however it has increased in frequency and even heard by dawn.

The clarion call of the neighbors is the sense of concern for not knowing the origin of the "coup" and especially because in this neighborhood runs the San Andreas fault line and the results are visible in an adjoining subdivision to the highway.

In interviews conducted by Noticias neighbors agree that the noise is heard on the ground, it's like something ran underground and then hit, and then an increased frequency and intensity of the blow, which makes windows and doors vibrate.

They also agree that the blow may be from some machinery or work being performed, but the journeys made by this House Editorial, left no evidence of a great work in the vicinity of the neighborhood. Also, on adjacent neighborhoods the phenomenon has not being noticed.

There are versions that people working on the expanding of the St. Joseph Medical Tower nearby, ran out because of the vibration felt in the building, however Noticias could not confirm this.

It is also noted that some argue that when it stops raining the beating stops, which is not verifiable, since last Monday's rain,  the heaviest rain of the last few years, the blow was felt, per neighbor's reports, between 05:30 and 06:00 am (CET), as they prepared to take their children to school.

Finally respondents indicated that the biggest concern is not knowing where the noise is coming from and know if there is danger or not.

Mysterious Booms Rattle Georgia Residents (Sept 6)

An unexplained boom rattled residents in southern Coweta Saturday night.

A series of booms also occurred about four weeks ago, said Lisa Sierra.

“Several of my neighbors as well as myself who live in the Trammell Road area have heard and experienced these noises,” Sierra said. She said she and her children were watching a movie Saturday when it happened.

“It was so loud that it shook our bedroom wall,” she said. “I ran outside to see what it could be but noticed nothing.”

Another boom followed about 20 minutes later, but the second one on Saturday was not as loud.

As for the boom last month, “My neighbor said that it shook her house. My son said everything shook and rattled,” she said.

The Coweta County Fire Department was dispatched at 9:57 Saturday to the area of Hwy. 54 and Cecil Hunter Road, regarding a possible explosion, said Assistant Chief Mitch Coggin.

“Units arrived in the area and could not locate anything,” Coggin said. “Our units searched the surrounding roads and still did not locate” the source of the loud noise.

Loud Boom in ArkLaTex a Mystery (Oct 13) 

The source of a loud boom heard at points across the ArkLaTex from Marshall to Keithville to Haughton remains a mystery at this hour.

"My couch came up off the floor a little bit, my back wall felt like it was going to cave in, it was so loud!" says Linda Stewart, who lives off of Shirley Francis Rd. in Greenwood.

The reverberation was heard and felt by staffers at KSLA News 12 at the studios on Fairfield Ave. in Shreveport's Highland neighborhood at 4:27 p.m. The concussion rattled windows. Meteorologist Jeff Castle says the closest incidence of possible thunder at that time was in Monroe, to the east in Ouachita Parish.

Some reports say it shook the ground.

KSLA News 12 has checked in with numerous law enforcement agencies and across the area and we continue to work to track down the source.

In spite of numerous reports, officials at Calumet in Shreveport and in Cotton Valley say there have been no explosions or incidents at either facility. Reports by other media organizations in the area that there was an explosion at Calumet are unsubstantiated, based on confirmation with the Shreveport Fire Department that there have been no calls whatsoever to the plant in Shreveport on this date.

Webster Parish Sheriff Gary Sexton says there have been no reports of anything amiss at Camp Minden, where explosives are stored in blast-resistant bunkers.

Several fire units have been at the scene of an oil tank fire believed to have been caused by lightning earlier in the day, but the Caddo Parish Sheriff's Office says there have been no explosions as a result of that incident.

Some reports describe the sound and accompanying vibration as a "sonic boom."

A spokesperson for Barksdale Air Force Base says it was not related to any activity on the base.

"Series of Sonic Booms" Rocks South Jersey Shore Town (Oct 29) 

Residents around Lower Township, New Jersey have turned to social media to confirm they were not alone in feeling the ground rumble repeatedly Wednesday afternoon.

“It seemed like the room moved. It’s didn’t shake, it didn’t twitch or anything, it just actually seemed like it moved,” Jo Ann Armstrong said.

It was a shakeup Jo Ann Armstrong just couldn’t figure out.

And she wasn’t alone.

In cities up and down the shore, people reported feeling the ground move or hearing a loud boom.

“I felt like a big, almost like a vibration, and then I heard what sounded like a truck overturning or something,” Jacquelyn Songalewski said.

It lasted just seconds but people jumped on social media hoping to figure it all out. Some didn’t know what to think, others thought possibly it was even an earthquake.

There were no reports of any earthquakes in the area by the U.S. Geological Survey.

Armstrong was relieved her friends experienced that same thing. For a moment she thought she was alone.

“Bizarre. Very bizarre,” she said.

Loud Boom in Kansas (Nov 13) 

24 hours after a 4.8 quake was felt in Salina, people from various parts of the city reported hearing a loud booming sound Thursday afternoon.

Salina police and fire department representatives said several people had called to inquire about the noise, but as of Thursday evening, the cause was not known.

The U.S. Geological Survey website reported no earthquake activity at that time, and representatives of the Smoky Hill Bombing Range reported no bombing activity at the time.

A Westar Energy representative said there had been no transformer explosions in Salina.

Some people posting online said their houses shook when they heard the boom, and some described it as sounding like a car had hit their house.

Multiple Booms Near Dayton Ohio Remain Unexplained (Nov 16)

Residents across southern Montgomery County and northern Warren County Sunday night heard three loud, earth-shaking booms.

The noises happened around 7 p.m., and prompted several calls to area 911 dispatchers and our newsroom.

One Miamisburg man said the loud booms sounded like an explosion, and that the last one sounded louder than the first.

“Our neighbors were in the street trying to determine what was going on,” he wrote in an email to the newsroom.“Loud booms being heard … Springboro, Miamisburg, Centerville, Kettering areas … any ideas?” read another email.

Local police and fire dispatchers said they received reports from residents of the loud booms that shook houses, but the cause was undetermined.The Montgomery County Sheriff’s Office sent deputies out to investigate, but there were no additional booms and there was no sign of damage in the area, according to the sheriff’s office.

Local utility companies also did not report having any incidents and there were no power outages in the area.

What WERE the loud bangs being heard across Britain? Twitter bombarded by reports of mysterious noises as military denies RAF jets were the cause

• Sounds reported last night from Glasgow to Croydon, south London
• Many suspected 'rumbling' sound was due to RAF jets' sonic booms
• But Ministry of Defence said none of its aircraft had been scrambled
• It came on same day mystery explosion forced closure of A1 road

PUBLISHED: 20:30 EST, 29 November 2014 | UPDATED: 20:37 EST, 29 November 2014

Britons have been left baffled by a string of 'loud bangs' which shook windows and disturbed children and pets from Glasgow to Devon to London.

Hundreds of Twitter users reported the sounds between around 9pm and 10pm last night, but the Ministry of Defence said it did not know what could have caused them.

Many suspected sonic booms similar to ones which shook Kent last month when two RAF jets intercepted a Latvian cargo plane in British airspace.

Mystery of the loud boom that shook homes over upstate New York AND the UK at exactly the same time despite being 3,000 miles apart

• On Saturday afternoon residents in upstate New York reported hearing a loud boom that shook their homes and rattled windows
• State police received numerous calls about the loud boom, but have no idea what caused it
• More than 3,000 miles away in the UK people took to social media to also report hearing unusual noises around the same time 
• One possible explanation is that the it could have been a meteorite breaking up in the atmosphere - which would result in a sonic boom 

A loud boom was reported by a number of people in upstate New York on Saturday afternoon at the same time as a similar noise was heard more than 3,000 miles away in the UK.

Residents in locations including Buffalo, Cheektowaga, Clarence and as far north as Niagara Falls took to social media to report the unusual noise at around 4:45 p.m. EST.

People described it as loud enough to shake their homes and rattle windows.

Scroll down for audio of the boom

'Just heard an explosion in Clarence that shook our house. Anyone else feel it? Our neighbors all felt it too,' wrote Lydia Von on the WGRZ Facebook page. 

For one resident in Alden, the noise was clearly a sign of extra terrestrial life.

'I was at home when a LARGE BOOM sound accrued. My house shook. Everyone in town heard and felt it. Some surroundings towns felt it too. There is no explanation,' the unnamed person wrote on UFO Stalker.

State police received numerous calls about the loud boom, but have no idea what caused it.

Meteorologists at the National Weather Service office on the grounds of the Buffalo International Airport did not report hearing or feeling anything at their office and do not believe that there could be a weather-related explanation.

FAA personnel at the control tower did not report seeing or hearing anything either.

One possible explanation is that the loud noise and ground shaking could have been a meteorite breaking up in the atmosphere, which would result in a sonic boom.

The U.S. Geological Survey did not report any seismic activity or earthquakes in the area at the time of the shaking, although a small earthquake did take place just two hours later.

The magnitude 1.5 quake was centered about four miles west of Lockport and happened at 6:27 p.m. local time. 

But Jana Pursley, a geophysicist with the USGS in Colorado, told WGRZ that it would be impossible to attribute the reported noises to the Lockport earthquake hours later. 

Any earthquake that registers 2.0 or less on the Richter scale is a microearthquake and no damaged was reported as a result of the quake, according to law enforcement agencies.

At the same time as residents in New York State reported hearing noises, hundreds of Twitter users in the UK reported hearing similar sounds - that also shook their windows.

An audio recording of the 'loud bangs', taken by a woman as she sat at home in Croydon, south London, might shed light on what is really behind the unexplained noise. 

Some people in Great Britain have suggested that unusual weather conditions might be the source, but the Met Office today dismissed the claims.

Others on Twitter suggested that it could be traced back to controlled explosions or military exercises. Meanwhile, conspiracy theorists took to social media to claim that aliens were to blame.

Claudia Angiletta said that she was watching TV at home when the unexplained sounds started.

She told MailOnline: 'I was just at home watching TV when I couldn't hear the program due to the loud noises. It was very distracting as it went on for ages.

Mystery Booms Rock Rhode Island (Dec 7)

Hundreds heard a mysterious boom Sunday night. Some heard it in Warwick and others in Coventry. But West Warwick residents heard it the loudest.

"At first I thought a car actually hit the house. It was so loud, the bang, everything in the house vibrated," Jeremy Dalnas said.

So much so, it caused a crack in Dalnas's front window, which he said was not there before Sunday night.

It was at about 8:20 p.m. when he and others in West Warwick heard and felt the thundering boom.

Dalnas said he even saw a flash of light first.

"You could see an orangey, yellow light. It was very bright. Almost like tow truck going by with its lights on, but then two seconds later after heard big bang," Dalnas said.

Across town, West Warwick resident Christine Shurtleff said Sunday night was the second time she's heard the boom in recent weeks.

"This felt like shaking, like the earth, so it made us think it was an earthquake," Shurtleff said.

Last year at this time, there was a small earthquake in Connecticut that caused loud booms. But officials at the Weston Observatory in Massachusetts ruled out any seismic activity in Rhode Island Sunday night.

National Grid said no transformers blew, and the Rhode Island National guard said it wasn't doing anything in the air.

West Warwick police said they took more than a dozen calls about the sound. Warwick police said they took three.

Andrew Shuster said he heard it leaving Warwick Mall.

"It was pretty far away, but at the same time it was so loud that my girlfriend, she ducked. My heart skipped a beat," Shuster said.

Local police departments said they found no source for the boom.

"I would like to know who's responsible for this. How do I get my window fixed now?" Dalnas said.

Still no clear answers 24 hours later.

"A second time and we still don't know what the first time was. You kind of wonder, what's going on?" Shurtleff said.

"I guess at this point it's still a mystery," Shuster said.

There was a similar situation in Cranston in December of last year, when residents heard a loud vibrating boom.

No definitive source was found.

And two years ago, also in December, residents in Warwick along the water and across the bay in Barrington reported a similar phenomenon. No clear answer.

This would make it the third year in a row for this mystery.

Loud Booms Reported Across North-Central Florida (Dec 12)

People all over the state are scratching their heads after loud booms shook buildings and windows from Tampa Bay to North Florida.

Meteor? Sonic boom? Military ordnance testing? Reports by authorities appear conflicted.

“Confirmation has been received by The Gilchrist County Emergency Management, that the loud 'booms' heard today is a 'Weapons Systems Test' 150 miles off the coast of Florida in the Gulf of Mexico. Tests will continue today and cease over the weekend and then resume Monday morning. The 'Weapons Systems Test' is a joint operation between the UNITED STATES NAVY AND AIR FORCE."

The Gilchrist County Sheriff's Office says the source of the booms was likely a military exercise.

There is, though, one other intriguing possibility: a meteor. WCJB-TV in Gainesville quotes James Albury, with Santa Fe College's Kika Silva Planetarium. He says the boom could have been a “fireball entering the atmosphere.”

Whatever the cause, FOX 13 meteorologist Paul Dellegatto says this a good time of year for sound to soar.

It’s actually the second mysterious bang within a week… And the first one remains still unexplained.

Riverside’s residents reported mystery booms and rumblings powerful enough to shake their homes on Sunday, December 28, 2014.

This is the second blast within one week after that experienced by many of Groveland and Riverside residents on Wednesday, December 24, 2014.

Riverside is located about three miles west of Blackfoot, while Groveland is about two miles northwest of Blackfoot. Riverside and Groveland have about 850 residents each.

Because no one reported Sunday night’s explosion to the Sheriff’s Office it’s unclear if the incident is going to be investigated.

A transformer explosion? An earthquake? A meteor disintegration?

So it will probably remain a sonic mystery.

Mysterious Boom In NE Pennsylvania (Jan 1)

Folks in Luzerne County heard a loud rumble, some even saying it shook their home.

It takes a lot to wake up 12-year-old Kendra Steltz of Lake Township.

“I was sleeping and all I heard was a big bang,” she said.

A big bang heard by more than just her. Many of you let Newswatch 16 know you heard the loud boom as well.

Police and emergency officials say several fire departments were dispatched to try to locate what the caused the boom in the back mountain but they had no luck locating it. They couldn’t find any damage either.

“Afterwards me and my daughter got into the car, and drove around the neighborhood to check out people’s houses and we saw nothing else so it was a mystery to us what it possibly could have been,” said Alice Steltz.

People in Lake Township say what’s even more surprising, is that no one has been able to figure out what exactly it was

Beatrice Price of Lake Township heard it and she felt it too.

“Everything vibrated,” explained Price. “It was short, it was a couple of seconds. Everything was vibrating.”

Vibrating so much, that her cows and pigs took cover. And that’s something she’s says she’s never seen happen like this before.

“We have people that hunt, and target practice. There’s guns, fireworks and it was way louder than that,” Price added.

There’s been plenty of accounts of what people thought they saw like a smoke trail in the sky. Nothing has been confirmed at this time. So for now, everyone is left to their ideas on what it could possibly be.

“It sounded like an explosion,” explained Price. “We have a gas place down the road. We thought maybe the gas place exploded but there’s no smoke or anything like that. So that was definitely not it.”

Mystery Booms NE of Los Angeles (Jan 2)

Several Victorville residents said they were awakened early Friday morning by at least three loud “booms” that were strong enough to shake the windows of their homes, but the source of the sounds remains a mystery.

The booms were heard at about 3:30 a.m. Reports came from neighborhoods near El Evado and Luna roads in Victorville and as far as Balsam Avenue on the other side of Interstate 15.

Local authorities said they could not identify the cause of the explosions.

Victor Valley Sheriff’s Station spokeswoman Pamela Hoffman said the station received reports of “loud booms” and officials checked the area and did not find anything. She said the cause of the noise was unknown.

If 911 dispatchers believed the noise was caused by fireworks then calls would have been transferred to local fire officials.

San Bernardino County Fire Capt. Jay Hausman and Engineer Jeff Allen both said they did not have any information about what could have caused the noises.

One resident said the explosion caused car alarms to sound in their neighborhood. Other residents posted on social media asking if an earthquake had occurred.

No significant earthquakes had been reported in the area in the last 24 hours, according to the U.S. Geological Society.

Unexplained Booms in Western Pennsylvania (Jan 4)

When the boom went off, about 8 p.m. Sunday, Diane Mangino was relaxing in her kitchen with her husband and her dogs.
 
"It's like a huge blast," she said. "You feel the house move and hear it at the same time."

Mangino said it was the third occurrence in about a week near her house. And she's not the only one to have heard and felt the phenomenon.

Residents in Lawrence County -- Ellport, Ellwood City, Wayne Township, Shenango Township -- have been burning up their Facebook feeds for at least a month with reports of the loud booms and accompanying ground tremors. And nobody can say conclusively what's causing them.

Brian Melcer, director of Lawrence County's Public Safety Department, said the county 911 dispatch center has been receiving calls about the booms and tremors, and police officers have been dispatched to investigate, to no avail.

Ray Beiersdorfer, a geology professor at Youngstown State University who has provided legislative testimony on seismic effects of the underground injection wells, said the earth's behavior in low-level earthquakes is consistent with the reports coming out of Lawrence County.

Sometimes low-intensity earthquakes can be accompanied with seismic activity, Beiersdorfer said, which results in a loud boom heard at the precise moment the earth begins to shake. But he said it's unlikely that the local booms -- at least the one at about 8 p.m. Sunday --  are being caused by an earthquake.

Beiersdorfer said neither the U.S. Geological Survey, an agency that monitors seismic activity throughout the nation, nor Columbia University, which also maintains seismic monitoring stations in the region, reported any earthquakes Sunday night of sufficient intensity to produce the phenomena described by Mangino and other county residents.

While no one can say conclusively what the booms are, plenty of people can say what probably isn't causing them. Amanda Witman, a spokeswoman for the state Department of Environmental Protection, said the department is unaware of any permits issued for blasting in the county.

The DEP's Northwestern Pennsylvania office in Meadville has not received any reports of any phenomena in the region, which includes Lawrence County, Witman said. She urged residents to contact the region's emergency response unit at 814-332-6945, or 800-373-3398 after hours, the next time they hear the boom.

There were no thunderstorms in the region Sunday night, according to the National Weather Service, and meteorologist Brad Rehak said he is unaware of any other meteorological phenomenon that might create a similar effect.

Emergency Management Agency in Tennessee Investigating Ongoing Mystery Booms (Jan 6)

The “booms” have been occurring “for quite some time,” and the Morristown-Hamblen Emergency Management Agency is working to find the source of the noise.

Chris Bell, director of the Morristown-Hamblen Emergency Management Agency in Morristown, said they have had widespread reports from people in the community about mysterious vibrations and unexplained loud noises.

“People report windows shaking or a boom that sounds like a transformer booming, or something running into their house,” Bell said.

According to Bell, EMA is working with the Center for Earthquake Research and Information and the Tennessee Emergency Management Agency to determine the cause of the disruption. CERI has deployed an instrument that detects seismic activity to help determine the source of the sounds.

“We had an instrument deployed here in town to figure out what those booms originate from,” he said. “The instrument is a seismic instrument that reads when there is ground shaking. We are still investigating.”

“There is speculation,” he said. “We are trying to rule out man-made (causes), and we believe that it could be something that is natural, but we cannot determine that until we have reviewed the data.

As of 10:30 a.m. Tuesday, more than two dozen people posted to the Morristown-Hamblen Emergency Management Agency Facebook page claiming they had experienced the disturbance.

The agency is asking the public to call 423-581-6225 and ask for Director Chris Bell or Teresa Ewing if they have heard the mysterious “booms.”​

Poleshift.ning gets two links in a mainstream news media article on mystery booms in Indiana.

Mysterious Booms Shake up Elkhart County Residents (Jan 3)

Weather was ruled out as a cause of the booms, whose source remains a mystery.

Some things may go bump in the night, but the things that went “boom” over the weekend remain a mystery.

In a region full of trains and areas that draw hunters, loud noises aren’t unusual, except when they jolt residents out of bed or rattle windows and walls.

That’s what happened when people across northern Indiana said they heard mysterious sounds Saturday, Jan. 3.

Mike Ropp, who lives on the north side of Elkhart, said he heard two loud booms Saturday — one around 3:30 p.m. and another about 10 minutes later.

“I went out and walked around, looking on all sides for any sign of smoke or anything else that might indicate a cause,” Ropp said in an email Monday, Jan. 5. “I went outside again, as did three more neighbors. One of them had driven around the area to our east (and) saw nothing.”

Ropp said he lives close to a fire station south of the Simonton Lake area, which draws some hunters and fireworks. But Saturday’s sound was unfamiliar.

“It sounded more powerful than an M-80 (firework),” he said. “It was more of a percussion sound. It didn’t have the sonic boom sound — that’s different.”

Kevin Reed, who also lives in the area, said he woke up to the sound at 5:30 a.m. that day.

“I thought maybe someone had broke into my house or that it was a gas explosion,” he said.

About 10 minutes after that, he said he heard emergency cars rushing down the street to a fire at Dunlap Plaza.

Elkhart city and county emergency dispatchers said Monday morning, Jan. 5, there were no other reports of fires, explosions or shots in the area during the times residents reported hearing the blasts.

Other areas, including a township in northeast Pennsylvania, reported hearing the boom. WNEP, an ABC affiliate there, reported residents heard the loud boom Jan. 1, called emergency units but found no trace of the sound’s source.

IS THIS THE FIRST TIME THIS HAS HAPPENED?

Yes and no.

During last winter’s extreme temperatures, parts of the country experienced “frost quakes” or cryoseism, according to Farmers’ Almanac. These reports of loud booms are caused by extreme low temperatures.

Cryoseism can happen when soil saturated by rain or melted snow drops from freezing to subzero temperatures in a small period of time, according to the almanac. As the moisture that seeps into the soil freezes, it expands and creates pressure on the bedrock, which can crack under the pressure, resulting in a loud popping noise. 

Reports of booms and shakes from last year in Minnesota, Illinois, Missouri, Indiana and even Canada were attributed to the extreme cold and frost, according to the L.A. Times.

However, the National Weather Service in Northern Indiana said that wasn’t the case this time.

“There was a lot of rain in the area and initially, we thought it might have been a rumble of thunder,” said Sam Lashley, senior meteorologist at the center. “But we’ve determined it was nothing weather-related.”

Even with Monday’s snow and extreme cold, Lashley said weekend temperatures “weren’t even close” to where a frost quake would happen.

SO WHAT WAS IT?

After hearing the booms, people posted their questions and working theories on social media.

1) Pole shift theory Enthusiasts at a blog that tracks natural disasters and space activity showed similar reports from December 2012 in Arizona, Texas, Alabama, Georgia and Rhode Island, which the blog attributed to seismic activity and tectonic plate shifts throughout North America.
However, the U.S. Geological Survey reported no unusual activity.

2) Meteor shower connection
There were also questions about the Quadrantid meteor shower Saturday, Jan. 3. Ongoing meteor showers can cause loud booms when they break up above Earth, L.A. Times reports. The meteor shower didn’t reach its peak until Saturday evening, long after the loud noises were reported in Elkhart County. Calls to NASA’s public communication office were not returned.  

3) Large jet
Some on social media speculated the sound was from a large jet, though Kevin Rector, manager at the office of aviation at the Indiana Department of Transportation’s aviation team, confirmed in an email Tuesday, Jan. 6, that he had no reports of aircraft traveling in the area at supersonic speeds, though he said he heard of several towns putting on fireworks displays for the New Year.

Mystery Booms Across Central Oklahoma (Jan 8)

Norman Police Department was flooded with calls around 11:30 Thursday morning from people all over the area who reported hearing loud booms and feeling vibrations.

Calls came in from all over central Oklahoma, including Newalla, Norman, Meeker, Lake Draper, Shawnee, Wellston, Agra and Parkland.

Anthony Young was just one of many who called 911. The mysterious booms rattled his home Thursday morning.

“We thought some nut was out here with explosives,” Young said.

Calls flooded in from Norman, Meeker and Shawnee.

Young said the booms shook his house so hard his windows rattled.

“It sounded like thunder but you could feel the ground shake and it was nothing like an earthquake. You know, we've felt earthquakes before, and it’s nothing like that,” he said.

Several law enforcement agencies are trying to find the source. The USGS said it didn’t get any reports of unusual sounds, and there were no earthquakes at the time.

Mystery Booms in SE Iowa (Jan 7)

Ottumwa residents have been posting their concerns on Facebook trying to figure out what could be causing the loud booms over the last 2 weeks.

KTVO decided to see what people had to say, and here are some of the comments we got.

Jean said, "I live 30 miles away from Ottumwa and it happened at my mom's house two weeks ago around 9 pm. It sounded like a bomb went off, it shook my house, nick knacks moved. I have lived in this area 54 years. It has never happened before. Someone needs to find out what it is."

And one Ottumwa resident told us the noises are indescribable.

"It's just so unexplainable because everybody throughout town has been hearing it, but yet there's some people that live two or three blocks away that don't hear a thing," said Ottumwa resident, Dana Jones.

For now, it's a mystery yet to be solved.

Mysterious Booms Continue in Central Oklahoma, Rattle Homes, Scare Livestock (Jan 9)

video

Experts are baffled by the mysterious booms shaking a city in central Oklahoma.

Oklahoma Geological Survey research seismologist Austin Holland says a series of thunderous booms rattled the Norman area at 11:19 a.m. Friday and that numerous more were reported in the same place around the same time Thursday.

Both Holland and National Weather Service meteorologist Matthew Day say they have no explanation for the booms that have been rattling houses and frightening livestock in the city on the southern edge of Oklahoma City.

Holland says there have been no earthquakes close enough to the area to be the cause of the booms. Day says a phenomenon known as cryoseisms (kry-oh-SY'-iz-uhmz) — which occurs when water freezes quickly in soil or rock, then expands and cracks — is also not to blame.

Authorities Baffled by Mysterious Boom in Lubbock Texas (Jan 6)

Hundreds of residents in Lubbock heard a loud boom around 6:05 p.m. Tuesday evening. Immediately, viewers took to Facebook to try to pinpoint the location and express their concern.

One viewer commented on Facebook saying it shook her house in Wolfforth, and many other viewers said it sounded like a car had ran into their garage.

Based on the viewers feedback, KAMC has gathered that the boom stretched from 19th and Milwaukee to as far as 110th and Indiana.

The Lubbock County Sheriff's Deputies went to investigate the area around 1585 and Brownfield Highway after receiving reports of the sound of an explosion. But after scoping the area for 30 minutes, they left empty handed.

So, what was the source of the loud boom that almost everyone heard but no one saw? The answer seems to be unknown.

Lynn County Architectural Testing, Inc., a company that conducts blast tests for commercial companies, said it had not conducted a test during the time the boom was reported.

There have been several accounts of what people thought they saw, like a large cloud of black smoke in the sky, however nothing has been confirmed. So for now, everyone is left speculating.

Mystery Boom Felt Throughout Cedar Valley Iowa (Jan 12)

Around 7:30 a.m. Monday, many people said a large boom could be heard and felt throughout the Waterloo/Cedar Falls area.

More than 60 people commented on KWWL's Facebook page, asking what it could have been.

"There was a huge boom," said Todd Seelye of Cedar Falls. "It shook the house, shook the windows, shook the floors. I thought it was a tanker car exploding or something."

We contacted the Cedar Falls Police and Cedar Falls Fire Department. Neither had any information on what the loud noise was. They said they would have been on scene if something happened.

We also contacted Cedar Falls Utilities because some believe it could have been some type of transformer or telephone wire that had possibly gone out, but if that was the case crews would have also been out. An official said that they had no outages or explosions on their end that would have caused the noise and rumble Monday morning.

Another theory we heard was an issue at the metal scrapyard. So, we stopped by the metal yard in Waterloo, who said that they produce noises all the time because of their auto shredder, but they said that nothing out of the ordinary came from the yard today.

KWWL talked to dozens and dozens of people this morning, with the majority of them saying they heard a loud noise. Some even said their homes were physically shaken because of it.

All and all, if it was an explosion or an outage, crews would have heard about it and been able to offer some insight on the issue. So at this point, we are all just left  wondering what the boom could have been.

Police Headquarters Evacuated After Mysterious Boom and Shaking (Jan 14)

The Downtown headquarters of the Columbus Ohio Police Division was evacuated for about 45 minutes yesterday while firefighters looked for the source of a loud noise that shook the building.

Nothing was found, said Sgt. David Pelphrey, a division spokesman. Early reports had said that an elevator dropped, but that wasn’t the case.

“It still remains a mystery,” Pelphrey said.

First-floor workers at 120 Marconi Blvd. heard the noise and felt shaking. Buildingwide alarms went off, prompting the evacuation at 12:15 p.m. Around 1 p.m., fire officials gave the all-clear to go back inside.

Mystery Boom in Southern UK (Jan 16)

A large bang or explosion sound has been reported in the Swindon area.

Wiltshire Police said it received three calls from people between 06:24 and 06:38 GMT saying they did not know where the noise had come from.

BBC Wiltshire received calls, texts and tweets from people in Rodbourne, Old Town and Pinehurst who heard the sound.

The British Geological Survey (BGS) said it was not thought to be down to an earth tremor, while the MoD scotched suggestions of a sonic boom.

The Wiltshire force said officers had not attended any explosion-related incidents.

A BGS seismologist scrutinised signals from the nearest seismograph sites to Swindon and found no evidence of a seismic disturbance of any kind, a spokesman for the society said.

"It may well be the case that people did experience something but, whatever it was, may have been so localised and too small to be recorded," he said.

Asked whether the noise could have been a sonic boom - the noise when jets break through the sound barrier - a spokeswoman for the Ministry of Defence (MoD) said: "There is nothing to suggest it was anything to do with us.

"There are no reports of activity from a military perspective."

Strange Booms Concern Georgia Residents (Jan 11)

Several Kennesaw residents were disturbed by loud, booming noises of an unknown origin on Sunday night.

The booms were reported intermittently between 6 and 9:30 p.m. Neither the nearby rock quarry nor the Tellus Science Museum could provide FOX 5 with a concrete explanation for the strange sounds.

Kennesaw police investigated the reports, but did not determine their cause.

Mystery Boom Rocks Southern Oklahoma (Feb 9)

Carter County residents are mystified by a powerful boom that shocked many as they started their work week.

"It was loud it scared me," said Kassidy Parrot. "I jumped."

Kassidy Parrott was just about to walk into her dentist's office in Healdton when she heard it.

"I got out of my car and all of the sudden there was this huge like, not even a bang more like maybe like a bomb went off," said Parrott.

But the mystery noise wasn't just heard in western Carter County.

Nearly 25 miles away, people in a neighborhood just west of Ardmore heard it too.

"It rattled the house," said Deidre Miller.

"I was kinda scared thinking, 'Is somebody breaking in?'" said Traci Chronister. "It was kind of weird because my dogs were going off."

Firefighters in Ardmore say it even shook their station on Rockford road.

"We all kinda looked at each other and wondered what it was," said Captain Chad Mansfield.

Mansfield says the boom he heard Monday morning was the loudest he's heard since joining the department 13 years ago.

"I've heard several small ones before," said Mansfield. "This seemed a lot louder. Like I said it did shake the station a little bit."

Seismologists with the Oklahoma Geological Survey say the boom may have been a sonic event.

But without a definitive answer, everyone feels like they're in the same boat.

"Scared the living daylights out of me," said Parrott.

Mystery Booms Capture Wide Attention in Central California (Feb 11)

Residents from across Mariposa county reported hearing a strange series of booms today.

So far, the phenomena defies explanation.

According to one report, the noises were loud enough to shake homes.

Booms were heard in Mariposa, Ponderosa Basin, Mt. Bullion, Midpines, Cathey's Valley, Lushmeadows and off Highway 140 near Yosemite.

Out-of-county reports came from Columbia, Jamestown, Raymond, Friant and elsewhere.

An information officer reached at the Lemoore Naval Air Station had no idea what might account for the booms.

A LOUD noise heard over South Shields has caused mystery and worry among residents

The noise heard in Jarrow has been likened to a jet aeroplane flying over head but it is not known what it is or where it is coming from.

Mary Finnigan, of Beverley Court, Jarrow, said lots of people have been talking about the strange sound since it started to be heard from lunchtime on Friday.

Mrs Finnigan said: “It reaches a crescendo and is quite frightening really.

“I’ve tried to get information from various people but no-one seems to know what it is.

“Many people have been looking to the skies. It sounds as though a plane suddenly flies over.

“It has caused some anxiety.”

Mrs Finnigan has contacted Rohm & Haas chemical factory, and Tedco enterprise agency to try and find out what it may be but to no avail.

She added: “I’ve never experienced this level of noise having lived here for over 30 years.”

Mysterious Quakes Rattling South Florida Homes (Feb 23)

Mysterious tremors have been plaguing Coral Gables residents repeatedly since the start of February.

The quakes are strong enough to rattle a cup of coffee but not spill it. Yet, no one seems to have an answer.

“These windows went rattling. The cat ran into the other room,” said Gables resident Matt Meehan. “My first thought was earthquake.”

Meehan said the chandelier was swaying back and forth.

“We’re not on a fault line, so what in the world was it?” he said.

 Boo Zamek, working at her Coral Gables home, felt the same thing earlier in the day.

“A very low subtle vibration,” said Zamek.

Coral Gables police said this isn’t the first time this has happened in the neighborhood.

“It’s happened three times in the past three weeks,” said Coral Gables police spokesperson Kelly Denham.

They sent officers out, but she said, “We can’t figure out what it is.”

“It’s concerning enough to call the police,” she added.

FPL spokesperson Bill Orlove doesn’t think his company has anything to do with.

“We did not have anything happen. It is not an electrical issue,” he said.

“It wasn’t alarming, it was just strange that’s all,” said Zamek.

And strange is the way it will remain as there are still no clear answers.

Don't see that anybody posted this story about the latest booms in Texas. Here's the link: http://irvingblog.dallasnews.com/2015/02/bombs-or-birdshot-mysterio...

As a side note, my husband and I have been feeling inexplicably extremely fatigued the last few days. Last night when I went to close up the chickens I looked at the western sky lots of cloud "ridges" extending south and west that made me think of Zeta Talk about stressed earth releasing particles. Anybody else think a good size earthquake is coming? My bones aren't hurting the way they did when Chile had their last big quake so I think if we get one it won't be that big, but I do think a large area will be affected.

Mystery Booms in Northwest Washington (Feb 25)

The source of home-rattling booms heard in Port Angeles area on Wednesday remains a mystery.

“We're not finding anything,” said Ron Cameron, chief criminal deputy for the Clallam County Sheriff's Office.

Several who reported hearing the booms on Facebook said the sounds seemed to be coming from the Strait of Juan de Fuca.

Spokesmen from the U.S. Coast Guard and U.S. Navy each said Thursday their units have not taken part in any activity that could produce loud booms in the Strait on Wednesday.

They said they had no knowledge of any event on the Strait that could explain the explosions.

The first report appears to have been placed at 2:40 p.m. Wednesday to Clallam County emergency dispatchers from a resident on Strait View Drive, east of Port Angeles, who reported several loud booms.

At the same time, Michelle Kaake heard two booms while in her home on O Street in west Port Angeles.

“It vibrated the floor and rattled windows,” Kaake said of the first boom.

The second boom came about five minutes later, she said.

Facebook postings told of people hearing the booms from Deer Park, in the foothills of the Olympic Mountains, to Joyce, about 15 miles west of Port Angeles.

The 129th EOD Company from Joint Base Lewis-McChord near Tacoma, which on Feb. 12 destroyed several pieces of naval ordnance that had washed ashore on the Dungeness National Wildlife Refuge — which was suspected to be from Canada — was not in the area and has received no calls for similar services in the Port Angeles area, said Joe Kubistek, base spokesman.

Events on the Canadian side of the Strait of Juan de Fuca have been heard in the past in Clallam County.

But not this time, it appears.

“Our demo range was not active yesterday,” said Sara Helmeczi, spokeswoman for Canadian Forces Base Esquimalt, which operates a demolition range on Bentinck Island, northwest of Port Angeles on the Canadian side of the Strait.

Could the booming sounds be coming from the earth?

Shallow earthquakes can cause loud booms, according to the U.S. Geological Survey.

“No one knows for sure, but scientists speculate that these 'booms' are probably small shallow earthquakes that are too small to be recorded,” the USGS website said.

A USGS spokesperson was not available for comment Thursday.

Mysterious Booms Continue to Rock NW Washington (Mar 13)

Quake map for March 6 -13, 2015

A new round of booming noises has disturbed residents of west Port Angeles and Joyce, who say the mysterious sounds shake their homes.

The rattling noises were reported at about 12:21 p.m. Wednesday, almost exactly two weeks after the last round of booms heard on the afternoon of Feb. 25, and again at about
9:35 a.m. Thursday.

“It sounded like it came from the direction of the Strait [of Juan de Fuca],” said Jim Haugen, who lives on Milwaukee Drive in west Port Angeles near the bluffs and reported the Wednesday boom.

“We were in the house, heard the boom and the house vibrated,” he said.

“It sounds similar to a sonic boom, [but there were] no planes in the area,” he added.

Haugen said he has been hearing and feeling the booming vibrations at his home for 13 years.

On Thursday morning, reports of booms from Joyce to downtown Port Angeles were made on Facebook.

Speculation on the cause of the booms has included naval military exercises in the Strait, thunder, sonic booms from Naval Air Station Whidbey Island aircraft, hunters and small, shallow earthquakes.

“We don't know what caused the booms that people have heard, but I can tell you they were not earthquakes,” said Leslie C. Gordon, geologist and spokeswoman for the U.S. Geological Survey for the Pacific Northwest.

Gordon said she checked with the University of Washington, which runs the seismic network in the Pacific Northwest, to see if there had been any seismic activity in the area.

“It is clear that the 'boom' was transmitted through air, as there was very little coupling with the ground. We looked but could not see anything on our seismograms,” UW researchers replied.

Gordon and her colleagues speculated that the sounds were sonic booms caused by military jets.

“I am only guessing based on similar incidents we have had in California,” she said.

If it was a sonic boom, it wasn't from a U.S. Navy aircraft, said Anthony Popp, spokesman for NAS Whidbey Island.

The Navy strictly adheres to aviation rules on supersonic flight operations, which restricts supersonic operations to designated areas or over the ocean, more than 30 miles offshore, Popp said.

Spokespeople with other military units in the region have said they have had no activity in the Strait during the times the booms were heard.

Those include Canadian Forces Base Esquimalt, which operates a demolition range on Bentinck Island northwest of Port Angeles on the Canadian side of the Strait, and Joint Base Lewis-McChord near Tacoma, which provides a demolition team for military training ordnance that occasionally washes up on beaches.
