ZetaTalk Q&A for February 25, 2012:
My question is regarding the YouTube strange sounds video posted by Gerard yesterday: http://www.youtube.com/watch?v=FUdZGm476yA On the Strange Sounds blog I posted a response as follows: Not trying to discredit anyone on the Montana video/audio. I believe what is recorded. But I'd really be interested in Zeta feedback on it because it reminds me of what happened in Close Encounters of the Third Kind - the musical sounds that the spacecraft emitted. The sound produced in Missoula is what is called in music a major seventh chord. In the key of C it would be C-E-G-B; in this case with an extra underlying G as the first note. I have a hard time believing that anything in nature could create this without help - possibly ET help. The notes are played separately up the scale/chord and then down the scale/chord. Could the Zetas please comment on what the source might be?

Missoula lies in a valley between mountain ranges that are riddled with rivers draining the steep mountain sides. If Kiev has multi-tonal trumpets because the reservoir is vibrating, and Belarus has horns because the river there is vibrating, then why should Missoula be exempt? The regions where the vibrating Earth plays music are where water is being vibrated. Elsewhere, it sounds like a roar, like Godzilla rising from the sea and roaming the land. Noise is sound where every frequency is heard. Music is controlled such that harmonics, or coinciding or duplicating frequencies are heard.
That several distinct tones were heard in Missoula, each in turn, only means that the body of water producing them increased its frequency from tone to tone. In Kiev, chords were heard, as more than one arm of the reservoir was set to vibrating. The thrumming or fan beating sound that preceded the Missoula tones was the rock layers being pulled apart, as the N American continent is being pulled into a bow, as we have often explained. As the jerking apart and rebound of the underlying rock layers picked up the pace, the pitchof the music the nearby river produced climbed. Simple as that.

ZetaTalk from the Jan, 21 2012 Q&A:
Strange sounds are heard all over the world! Can the Zetas comment? http://www.godlikeproductions.com/forum1/message1756314/pg1 [and from another] My question pertains to the noises, similar to the ones heard in Kiev, happening over the past week all over the world. http://www.youtube.com/watch?v=GZ2ZcmMxehk&feature=channel_video_title Here is a video compilation of some of the places experiencing these noises, some of the videos have been accused of being a hoax, and the essence of my question for the Zetas is; what is going on? I've managed to locate some videos from Australia, posted recently, that seem to verify what others have posted from other users located in different parts of Australia, one of the videos located here. It would appear we are seeing the "Kiev Effect" taking place worldwide now, and only recently on this scale; there is obviously more to this than meets the eye, would the Zetas care to comment?

Where initially only a hum, and only in certain notorious parts of the world, rock under stress has become noisy. Known as the Taos hum, the sound of a diesel engine running somewhere underground was an early entry. Then the Seattle drums entered the arena, rhythmic booming which was ascribed to flapping manhole covers. Booms from snapping and heaving rock were reported in the New Madrid region and humming along the St. Lawrence Seaway increased.
But in 2011, it became clear that where we predicted that the Earth would moan during the 5.9 days of rotation stoppage, it was not going to be silent between then and now. The trumpets of Kiev and the horns of Belarus went viral on the Internet, followed quickly by a roar over Tampa Bay that sounded like Godzilla emerging from the sea. Now, in early 2012, this has spread to the drums of Costa Rica and the howl of Alberta and the Borneo snore.
Where is this leading? At least half the Earth, at any given point in time, will be having some sort of tension in its rock. Clapping and grinding fault lines, vibrating bodies of water, trembling rock strata resisting being pulled apart, and snapping rock under compression or being bent. All will be noisy, and the most likely reaction among those who hear it will be to conclude that the End Times have arrived. However known in various cultures around the world, allhave some reference to the coming times. The establishment will be unable to explain away these sounds, and once again the Internet will be sought and will lead inevitably to our explanations.

Strange Sound Heard Throughout Costa Rica
January 11, 2012
http://www.costaricanewssite.com/strange-sound-heard-throughout-cos...
Is it the mysterious sound of the so-called coming Apocalypse? Some think that the mysterious sound heard in Costa Rica at around 12:30am this morning is exactly that. It is important to note that this is not the wind nor was it filmed anywhere near the ocean. The sound was heard throughout the entire country from Heredia to Perez Zeledon. The Costa Rica Volcanologist and Seismologist Organization is saying there is no Earth movements recorded at the time of the strange sound.

There is a subset of the Caribbean Plate called the Panama Plate, though this subset moves as one with the Caribbean Plate. Nevertheless, there is a fault line running through Costa Rica, and during the incessant pressure of the slow moving S American roll fault lines can pull apart and bang back together again, like clapping. As the recent cold spells in India reveal, the N Pole of Earth is pushed violently away when the Sun is over New Zealand and the magnetic N Pole of Earth (currently over Siberia) comes up over the horizon. This equates to midnight in Costa Rica, which is when the drums were heard. Residents there should get used to these midnight drums, which will be with them for some time.

Mystery Boom Reported in Southeast Georgia (March 15) -
Reports of loud sound, earth shaking reports come from 5 counties.
It wasn't an earthquake that rattled windows and store shelves early, but residents across Southeast Georgia heard and felt something big Thursday morning.
"My wife and I, we heard this loud noise -- this booming noise," said Officer Todd Rhodes of the Brunswick Police Department. "It was a noise that literally shook our home."
When Rhodes got to work, he learned his 911 center was swamped with calls of people with similar reports.
"Everyone was very concerned," Rhodes said. "There was some panic there because you know when you hear that noise as far-reaching as it was, and not only hearing it but feeling it, you want to know, 'What is this?'"
Reports came in to Channel 4's newsroom from Nahunta to Folkston about a loud noise and buildings shaking between 8:15 and 8:30 a.m.
"Up at City Hall, they said they felt something shake," said Folkston resident Ericka Smith.
The Georgia State Patrol says they received calls from Brantley, Camden, Charlton, Glynn and McIntosh counties asking about the boom and rumble.
The manager at Satilla Grocery in Waynesville reviewed surveillance video that showed the building shaking.
"Next thing I know we just hear this big old rattle," Deanna Brower said. "The doors here rattled really hard, and we thought maybe somebody had actually hit the doors or something."
The U.S. Geological Survey said there was no indication of a earthquake in the area, but had hear reports of either a sonic boom or other event that cause the ground to rumble.
Naval Submarine Base Kings Bay said they were not conducting any operations that would have caused a sonic boom or explosion.
Channel 4 checked with the Navy and Marines, which said there were two F/A-18 Super Hornets flying over Georgia at the time, but they were nowhere close to the speed of sound.
The Federal Aviation Administration said it had no record of any aircraft going supersonic in the area on Thursday.
Late in the day, the Georgia Department of Emergency Management said Air Force jets were doing training exercises off the coast of Brunswick and one got too close to land.
The fact that no one can explain what caused the boom and shake for most of the day was disconcerting to local residents.
"We haven't heard anything, and that's sad," Rhodes said mid-afternon. "So many people here have felt that and we don’t have a clue what it was."
NOTE: Watch the video Earth movement captured by grocery store surveillance camera (1:20).

Another likely St. Lawrence Seaway adjustment -
Mystery Boom in Barrie, Ontario (March 24)
Residents left wondering after strange noise; similar noise reported in Wisconsin.
Sounds described as ‘sonic booms’ reported in the Green Bay area of Wisconsin have been declared a mini earthquake, but similar sounds heard in Barrie’s northwest end have yet to be identified.
Around 10 p.m., Tuesday, families on Wallace Drive took to the street after a loud sound ripped through the neighbourhood causing concern among residents.
Residents in the Barrie neighbourhood described the sound as a dump truck hitting a house, a propane tank exploding and a sonic boom displacement of air.
Residents in Clintonville, Wis., reported hearing similar sounds Sunday evening and Monday morning.
After investigating, the U.S. Geological Survey announced on Thursday the sounds resulted from a 1.5-magnitude earthquake, which can be felt within a eight-kilometre radius.
Barrie and Clintonville share the same latitude.
No physical evidence was found to determine what caused the sound in the Wallace Drive area in Barrie.
Yvonne Buchanan lives in the area on McVeigh Drive and said the sound had her more than confused.
“I thought it was a propane tank (blowing up) or some crazy thing,” she said. “I never thought anything of it because we didn’t hear any sirens or anything.”
Barrie police said there were no calls for service in the area at the time or reports matching a loud sound. A sonic boom is a loud sound similar to one caused by an explosion, but is the result of supersonic travel, usually from an aircraft breaking the speed of sound.
The Canadian 1 Air Division’s CF-18 is the only Canadian aircraft capable of supersonic travel.
Public affairs officer Capt. Holly Brown, with the air division in Manitoba, said two CF-18 planes flew from 4 Wing Bagotville in Quebec to 8 Wing Trenton in Ontario on Wednesday, but didn’t reach speeds fast enough to break the sound barrier.
“We’ve had queries in the past where people have reported a sonic boom and there was no CF-18 activity at all,” she said. “Typically, our CF-18s don’t break the sound barrier while they’re transiting.”
Corinna Horton was getting ready for work at 5:30 a.m. on Wednesday when the lights flickered just before a sonic boom rattled her Ottawa-area home.
“All of a sudden the lights flickered and I thought it was a pulse and then all of a sudden, boom,” she told the Examiner. “It was still dark out and all the birds started going crazy outside and a couple of dogs started to bark.”
When the sonic sound pierced the air, Horton said she could feel it all around her.
“The fact that the lights flickered beforehand I found very interesting,” she said. “At first, I thought it was a blast like a demolition bomb, but there’s no way they would have given permission for that that early.”
Brown didn’t rule out aircraft completely, but said because Nav Canada monitors the country’s skies, the military doesn’t always know who’s flying above us.
“If it was U.S. Air Force aircraft we don’t necessarily know about it because if they filed a flight plan with Nav Canada it doesn’t even come to our attention,” she said. “There are a lot of things that make loud noises out there. If there are low clouds, it can make things sound a lot louder.”
Even though Clintonville has answers, Buchanan said she knows what she heard was real.
“It was loud,” she said. “I definitely heard something.”
“It was like a loud sonic boom. When I went outside, numerous neighbours came out to see what happened,” Rob Higgins said. “No one could see anything. Some people said it sounded like a major car crash.”
“Originally, I thought some huge thing was thrown at our house. Not a car, but maybe a big barrel or something large,” Higgins added.
“I went outside and realized everyone heard something and it couldn’t have just been our house.”

Increasing stress on the Atlantic Rift -
Mystery Booms in Bigouden, France (translated)
March 23, 2012 at 8:31
A "thud" and even "three roar" were heard in heaven Bigouden Wednesday night. A phenomenon that remains unexplained and apparently has repeated last night from north to south of Finistere. And also in Côtes d'Armor and Morbihan. But where do these sounds? [Bring your testimony]
"A thud as if a child was stamping his feet on the wall of the neighbor." Testimonials are legions Bigouden. But not only. Combrit Chateauneuf-du-Faou through Briec, Quimper, Plogastel-Saint-Germain, Pont l'Abbé, Tréméoc, Cockles, Plobannalec-Lesconil or Clohars-Fouesnant, many people on Wednesday to 21h, were intrigued by the phenomenon. Alluded to here "the house (who) just shake three times." We're talking about "three strong rumblings" that "have rattled houses" and even "small awakened." Some, meanwhile, heard "muffled explosions" while others are convinced that this is "an earthquake".
Neither earthquake, nor maneuver
Contacted yesterday, the central office Seismological French (BCSF) states have nothing abnormal registered in this area. And for its size, Chateauneuf-du-Faou Clohars-Fouesnant, the blasts and aftershocks felt "were enregistréess'il was an earthquake, at least three forces". In 2005, Bigoudens remember, an earthquake on the fault south Armorican and a magnitude 3 on the Richter scale had caused the same feelings. What then of these explosions heard and felt? An air-borne? Regional Centre of Western navigation, it is shown not to record this kind of phenomenon.
So, it is with the military that the eyes are. Moreover, some also said they heard a helicopter. Preceded, it is true, "three thumps" recalling "the thunder". One thinks of the aircraft. When questioned, the communications department of the Brest Maritime Prefecture said that there was no Navy operation and even less involving helicopters. Side of the Joint Staff of the area of defense and security northwest (OGZDS), it is formal. Not operating, "no supersonic flight." Bizarre. Especially in March2003, three earthquakes had already hit the Bigouden ... The phenomenon was also remained unexplained.

"The Hum" in Ireland ongoing for the past year -
Tuesday, April 03, 2012
Locals despair as ‘The Hum’ makes life a living hell.
IT’S there. All day, every day; all night, every night.
But nobody has even the remotest idea of what it is or what could possibly be causing it.
It has become known simply as The Hum, which is the only description despairing locals can find to adequately describe a constant, pulsating, low-frequency noise, the source of which cannot be traced, despite best efforts.
When frustrated residents in the tranquil Kerry parish of Beaufort went public to tell how their lives have been made a living hell by the mystery noise — which is ringing in their ears all day and disrupting their sleep by night — little did they know the impact it would have.
Fascinated audiologists with sophisticated detection equipment made a beeline for the remote townland of Glencuttane, 15km from tourist hotspot Killarney, at the foot of Carrauntoohil mountain.
Excitable, self-described ghosthunters weren’t far behind and much to the annoyance of residents, some media rather impishly devised conspiracy theories that ranged from mildly amusing to ridiculous.
But the saga finally got the official platform locals insist it deserved in recent days when South Kerry TD Michael Healy-Rae raised the matter in the Dáil, via a series of parliamentary questions directed at Phil Hogan, the environment minister.
"I asked the minister to send out people to try and come to the bottom of it," said Mr Healy-Rae, who personally heard the noise when he met with disgruntled locals.
But Mr Hogan could offer no solution and little consolation other than to advise the residents to voice their concerns to Kerry County Council’s environment office and an investigation might be sanctioned.
The official response has been lambasted by Mr Healy-Rae as "away with the fairies gobbledygook".
Council engineers have already ruled out a local authority water pumping station as a possible factor and weary locals, now at the end of their collective tether, had already determined that there are no mobile phone masts, windmills or generators in the area that could be the source of the noise.
Furthermore, the ESB has assured them that the problem is not due to any high-tension overhead wires and while sound technicians have been able to confirm that the noise has a vibrating, low frequency, they are no closer to identifying any potential explanation.
Some householders in Beaufort have been hearing the bizarre humming sound since April of last year and, at this stage, they say it is making their lives a complete misery.
"We are nearly gone out of our minds because we can’t get a decent night of sleep and it’s there every day," said one, who described the noise as being similar to a diesel engine ticking over in a nearby field. "There are times when you absolutely can’t ignore it because it’s so present, mostly at night because it’s so quiet."
He said the irritating noise is even more noticeable inside dwellings and despite extensive insulation, houses appear to vibrate, particularly in the stillness after dark.
Rather unusually, not everybody can identify with the low buzzing noise and locals acknowledge that if they gathered 10 people in one room, they estimate that just two would be able to hear it. That said, at least a dozen families over a 5km radius have come forward to divulge that they have been disturbed by the baffling aural interference.
One resident even went to the extreme of seeking help from his family doctor and was relieved to learn that he didn’t have a problem with his hearing.
Others, who can’t sleep at night, have taken to wearing earplugs in an attempt to block out the mystery noise.
In the absence of any logical explanation, there is growing belief by some observers that the noise might possibly be linked to a weird worldwide phenomenon that has become known, simply, as The Hum.
Similar mystery noises, all involving persistent and invasive low-frequency humming sounds, have been reported in many parts of the world and complaints have been voiced by residents in several locations, including England, Russia, New Mexico, New Zealand and Indiana.
Inconclusive research into possible causes for The Hum has been conducted in universities in Florida, Oklahoma and Auckland, but, despite the best efforts of experienced boffins, no real progress has been made.
Beaufort residents are quick to stress, however, that they are not suggesting for one minute that the noise that is impacting so negatively on their daily lives is linked in any way to the humming sounds detected elsewhere.
"We don’t know what it is and it’s as simple as that.
"We’re hoping that we might get some help from somewhere to try and investigate this and see what it might be," said one concerned local.

Mystery Booms in Falls Church, Virginia -
Strange sounds were caught on tape in Falls Church, Virginia in the dead of night. Suddenly a series of loud booms can be heard. They sound like the clanging of construction, but the "ear witness" claims that's impossible.
She also rules out the highway nearby as the source. If it was the highway, that must have been one terrible crash. Which happens over and over again every few seconds.
These mystery booms sound much more like what residents of Clintonville, WI, experienced last month for over a week, causing them to lose a lot of sleep. They also happened at night. Can these weird sounds be related?

Mystery Boom in San Diego, CA (April 13) -
NBCSanDiego received a number of reports from residents of a shaking or a loud noise just before 9 a.m.
The U.S. Geological Survey has not reported a nearby earthquake.
Officials at MCAS Miramar said the noise or vibration was not a sonic boom from their aircraft.
Reports came in from different sections of the county including La Mesa, University City, Point Loma, Paradise Hills and La Jolla.
Marielle Bravo-Saltzman of Carmel Valley posted to NBCSanDiego's Facebook page, "I felt a shake at 8:38, but no boom."
Paul Prince of Pacific Beach sent a note to @nbcsandiego via Twitter "All my windows shook in the PB area..."
San Diego State University Professor Emeritus Pat Abbott felt and heard it and stepped outside his home.
“The only time you hear an earthquake is when you’re directly over the epicenter,” Abbott said.
In his opinion, the sound was atmospheric.
Thunder and lightning were in the forecast Friday, but NBC 7 Meterologist Jodi Kodesh looked into it and said there weren't any storm cells near the area producing thunder and lightning at that time.
When lightning strikes, the discharge of energy can be felt 5 to 10 miles away as a rumble or a boom, Kodesh said.
The closest rumble of thunder at the time would have been north of Los Angeles.
Sometimes, a military exercise known as chaff can cause a similar sound.
Strips of metal foil dropped by an aircraft are used to temporarily hide an aircraft from radar detection.
The National Weather Service couldn't confirm if the sound was a result of chaff and an MCAS Miramar official told us he was not aware of possible chaff in the area.

Ottawa Investigates Mysterious Windsor Hum (April 20)
Thousands of complaints have been received from Canadians disturbed by rumblings in the Windsor area. The so-called Windsor hum has affected people mainly in the city's west end, but also some in Essex County.
"The Windsor hum is having a negative effect on the day-to-day lives of Windsor residents,”
A federal study suggests the Hum may originate from the U.S. side of the Detroit River, in the general area of Zug Island.
According to the media release, while in the area, Dechert will hold meetings with Windsor Mayor Eddie Francis and with Great Lakes stakeholders, including representatives of the Great Lakes Commission, the Council of Great Lakes Industries, the Southeast Michigan Council of Governments and the Regional Office of the International Joint Commission.
Dechert will also meet with U.S. and Michigan political officials.

Land tremors, rumbling and loud bangs were reported to have been felt and heard by many people down the Aberdeenshire coast on Tuesday evening. Grampian Police confirmed they received a number of calls between 8.45pm and 11.15pm on Tuesday from concered members of the public. The rumbling is thought to have been heard and felt in a number of coastal areas including Stonehaven, Newtonhill, Muchalls, Portlethen, Inverbervie, Gourdon and St Cyrus and some reports were received from as far north as Cove and Torry.
Residents who felt the tremors said they felt their house shaking and windows rattling. The sounds were described as being like thunder coming from the ground, someone banging on a window, a motorbike engine starting up and dying quickly or the sudden sound of a train with no approaching or leaving noise. Many were left baffled at what they had heard and thought it was just something that had happened within their own homes or in the surrounding area, yet when other people raised their concern about the noise and movement an increasing number of people began saying they heard similar noises and felt tremors throughout the evening.

Some Corona del Mar residents heard a strange “loud boom/bang” about 12:20 a.m. Tuesday, and police confirmed they received two calls about the noise.
“We had two reports of a loud ’shot’ at approximately 12:20 a.m.,” said Kathy Lowe, a Newport Beach Police Department spokeswoman. One of the callers was on Rivera Terrace in the Corona Highlands neighborhood, and the other was near Fourth and Marguerite avenues. Corona del Mar Today readers in the village also reported hearing the noise.
“Officers responded to the area,” Lowe said. “However they were unable to locate the cause of the noise. We did not receive any additional related calls.”
One Corona del Mar Today reader said the noise was a “very loud boom/bang” that was louder than a gun.
“It definitely woke up us up,” the reader said in an email. “It was louder than a gun I believe…it scared me wide awake!”

Mystery Booms and Shaking Along the St. Lawrence, Alexandria Ontario (June 14) -
http://www.wwnytv.com/news/local/Feedback-People-Report-Mysterious-...
"Boom, crack - and we wonder, what is this," said Dave Roberts, who owns the Aqua Zoo on Route 12.
"It's like a mini-shotgun blast or something. It's very quick, but instead of being in the air around you, it's coming from the ground underneath you," said Bob Vrooman, who owns Pinehurst Motel on Route 12.
Roberts has heard the blasts and felt the shaking for the last two weeks.
"Did you hear that one? Did you hear the one last night at 2:30? Did you feel the one at four o'clock," said Roberts.
But here's the thing, seismology reports do not show any activity in the area over the last week and officials with Fort Drum say they aren't responsible for the shaking either.
"Everybody has the same concern, they just want to know what exactly is happening," said Vrooman.
While they haven't been able to find a concrete answer, some residents do have a theory - that salt used by the Department of Transportation over the years has seeped into the ground, causing rocks underneath to shift and move.
"Could that salt now be crusting, and as it crusts it swells and could possibly be lifting enormous rocks," said Roberts.
Calls to the DOT haven't been returned.
That means the search for the source of the shaking will continue.

Mystery Noise in Victoria, Australia Coincident With Largest Quake in 3 Years, 40 Aftershocks (June 19) -
http://www.standard.net.au/news/local/news/general/mystery-noise-ca...
A mystery noise is driving several Warrnambool residents to despair one even selling her house to escape the incessant drone.
Two residents in Mitchell Street and two others, less than a kilometre away in Alice Place, have aired their annoyance over what they describe as a low, turbine-like noise in their north-east neighbourhood.
"I just can't sleep and even when I put in ear plugs I can hear it," one woman said.
"I've got chronic fatigue syndrome and just can't rest, yet I still have to go to work.
"I've sold my house and am moving to another area."
Three other residents also said they too found it hard to sleep, especially on calm nights when the sound was more noticeable. "It's not excessive, just irritating and sometimes it keeps me awake night after night," one retired woman said.
"A pumping station has gone in near the Aberline Road roundabout. Maybe that's it."
A mother and daughter in Alice Place described the noise as intermittent.
"It drives me insane sometimes," the mother said.
"I put in ear plugs and pull the bed covers up high, but it still bugs me. It's very strange. At first I thought it must have been the smart meter."
Her daughter described the sound as "kind of like a really low turning noise". "It wakes me up in the mornings."
Magnitude-5.4 quake Shakes Southern Victoria (June 19) -
http://www.abc.net.au/news/2012-06-19/magnitude-54-quake-shakes-sou...
South-east Victoria has been rocked by more than 40 aftershocks after a magnitude-5.4 earthquake hit near Moe in Gippsland on Tuesday night.
The tremor struck 16 kilometres west of Moe, but was felt in the centre of Melbourne and in suburbs across the city's west and south-east.
Initially measured at magnitude-5.3, it was also felt as far north as Shepparton and even Albury on the border with New South Wales.
The SES said it received dozens of calls for help for cracked walls and ceilings and a collapsed garage and chimney.
Residents and business owners are being urged to check their properties for damage before returning inside.
But the SES says there have been no reports of major damage.
Residents reported hearing a roaring noise as the quake hit just before 9:00pm at a depth of about 10km.
An SES spokesman told ABC News Breakfast there were 850 calls to emergency services in the first hour after the quake.
"The damage we've seen has largely been minor cracks in walls and a garage that has had some damage. We've also seen some shops that have had some stock come off the shelves," he said.
He said some homes did lose power after the quake but there have been no significant reports of gas leaks.
One of Australia's top earthquake specialists says last night's earthquake was the latest and biggest in a cluster spanning three years in the region.

Mysterious Booms in Rockaway, New Jersey (July 16 and 18) -
Police were inundated with calls Monday night from residents who reported hearing and feeling three loud booms in succession starting at around 10 p.m., according to Chief of Police Douglas Scheer, who investigated the reports and contacted numerous agencies in a quest to explain what had happened.
“They were enough to jar residents in their homes and cause them to come outside,” Scheer said. “We believed at the time it could have been some sort of explosion but as we spoke to more and more residents we determined it had to have come from underground.”
The booms were all felt in a half square mile area centered around Rockaway, Franklin and Lincoln avenues in the borough, Scheer said.
“They caused homes to shake and people to become very nervous,” Scheer said. “We had calls from people thinking people were breaking into their homes or something was blowing up.”
Eric Nordmann, who lives on Rockaway Avenue, said the “events/episodes” sounded like an underground explosion.
“My entire house shook for a very brief time, but not just my house many houses on my street,” Nordmann said.
The same type of noise was heard again on Wednesday at 2 a.m. and then again at 4 a.m. in the same general area, Scheer said.
“It was enough to make residents feel they needed to check things out and it was felt at the police department,” Scheer said. “We called all the same people again and they did not have answers.”

Mystery Booms Startle Residents in Temuka, New Zealand (June 29) -
http://www.stuff.co.nz/timaru-herald/news/7195609/Big-bangs-source-...
Mysterious loud bangs in the Temuka area are not believed to be earthquakes, a GNS spokesperson says.
Paleoecologist doctor Ursula Cochran, of GNS Science, said the ''events'' reported to The Timaru Herald over the last three days have not been recorded as earthquakes by Geonet so believed ''there must be another explanation'' for them.
Temuka residents have contacted the Herald with their experiences - many saying the loud bangs had been followed by shaking.
Dr Cochran said there had been no reports of earthquakes at the times people had been hearing the bangs.
''The fact it hasn't registered on the Geonet website as an earthquake, it's probably more local. It does sound pretty unusual.''
Temuka resident Jenny Bolitho is among the many people who have been mystified by the events.
''My husband and I live on Springfield Road, just 50 metres from the substation,'' she said.
''We were rudely woken by this horrible noise on Wednesday night, at first thinking it was an earthquake. My husband checked our property but couldn't find anything amiss. The next morning there was another bang, I was sitting at the time and felt the vibration through the stool on which I was sitting, which seemed to come through the [concrete] floor.''
Betty Weavers has also heard the noises, and was pleased to know others had too.
''We live in Seddon Street and have been mystified by the bangs and rattles.''
She said the experience had been frightening.
''It is quite scary as we think someone is trying to force their way through the front door and this makes other doors rattle.''
She described the bangs as ''strange'', which seem to occur at ''any time''.
Ann Behrnes, who lives a couple of paddocks away from the Temuka substation, thought the bangs she was hearing were explosions.
She heard the first one on Wednesday at 11.30pm, which prompted her to get out of bed to investigate. She heard another strange noise at 7am on Thursday, which sounded like a train and was followed by a ''big'' shake.
It was enough to make her consider texting family in Christchurch to see if they had, had another quake there. ''I checked quake websites later in the morning, amazed that nothing had been recorded,'' she said.

Mysterious Roar Heard in Huon Vally, Tasmania AU (July 15)
http://www.themercury.com.au/article/2012/07/25/349301_tasmania-new...
Hundreds of residents are still unable to explain the source of the 20-second roar.
The noise was first reported after a Huonville dam bank burst on July 15, causing the evacuation of 100 residents.
"It woke me up about 10pm we had no idea what was going on at the time but in hindsight maybe it was the dam breaking," a Scenic Hill Drive resident said on July 16.
But the council said the noise would not have been caused by the dam incident.
The Mercury yesterday spoke to local police, retailers and council employees in the Huonville and Cygnet areas after being contacted by concerned residents wanting answers. Everyone heard the noise but no one knew what caused it.
The Bureau of Meteorology says it was most likely a particularly extreme thunder blast.
"But it sounded very different to thunder," unconvinced Cygnet resident Kamal Singh said yesterday.
"My partner and I were lying in bed asking 'what the hell was that'."

Mystery Boom on the Indo-Australian Plate Border (Aug 6) -
http://www.hindustantimes.com/Punjab/Ludhiana/Mysterious-loud-bang-...
INDIA - A mysterious loud sound around 12.30pm in the city on Monday created panic among Ludhiana residents who called up police control room and fire brigade during the day to seek information. The impact of the high-velocity sound was such that windowpane of many buildings were shattered in some areas of the city.
Soon after the deafening sound, the city was rife with rumours that a bomb blast had occurred at Ludhiana railway station. Some rumours talked of similar incidents at the bus stand, Clock Tower, Dholewal, Aarti Chowk, Pakhowal road, Model Town and industrial area.
Police commissioner Ishwar Singh too said that he had indeed heard the loud bang. Later, as his phone started ringing and people started to inquire, he came to know about the rumours. Within no time, he asked his subordinates to clarify the situation to city residents.
Personnel deputed at PCR remained busy in the afternoon, trying to allay fears of people who flooded them with calls after hearing the loud sound.
Police said the members of the worried public asked them if a bomb blast had occurred in the city. Interestingly, PCR received double the around 2,200 calls they receive on any day in routine. Same calls were also made to the control rooms of 108 ambulance service and fire brigade.
As rumours on the loud sound persisted, police made use of social media sites on the Internet to clarify that the loud sound was probably a thunderclap, which was heard in many parts of Ludhiana.
Police advised people not to panic as no blast was reported anywhere in the city.
Naresh Vig, public relation officer with the ministry of defence, said that the sound might have emanated from an aircraft breaking sound barrier."However, there was no activity of air force in Ludhiana area on Monday, as per our information. So there is no possibility of the sound to be sonic boom," Vig said.
Dr KK Gill, assistant agricultural meteorologist, PAU said, "We tried to get information regarding the loud bang from the doppler radar set up in Patiala. But the radar recorded nothing. As of now, nothing can be said with absolute certainty."

Swedes wake up to Monday earthquake
Published: 6 Aug 12 08:00 CET
“We woke up at 5am by the whole house shaking. The walls were groaning. We haven’t had a chance to check if there are any cracks anywhere,” said Anne and Mathias Elm in Ängelholm to news agency TT.
In the village of Skogaby, close to Laholm, villagers first thought a freight train had derailed close by.
“We live on a hill facing the sea. For a moment I feared the house was sliding down,“ one villager said.
According to seismologist Reynir Bödvarsson at Uppsala University, the quake measured just above 4 on the Richter scale, rather rare for Sweden.
“Quakes of this magnitude happen maybe every ten years in the Sweden-Denmark area. It is rather special,” said Bödvarsson to TT.
Quakes that measure around 3 on the Richter scale occur about three times a year in Sweden, according to Bödvarsson. Tremors reaching 2 on the scale occur some ten times a year.
“The Kattegatt strait is an area which sometimes sees these somewhat larger quakes. They happen every now and again, but it is a bit unusual that they reach this magnitude,” Bödvarsson told TT.
Police in Halmstad reported receiving some 30 calls after the quake and said that in their offices on the fourth floor, windows were shaking and furniture wobbling but that was all.
Bödvarsson told TT that a quake of this magnitude should pose no threat to buildings and that any potential after-quakes should be so small that they will probably not even be noticed.
According to the US geological survey, USGS, the quake occurred in the sea at an approximate depth of 5.8 kilometres beneath the ocean some 51 km south west of Falkenberg, 60 km north west of Höganäs, 61 km west of Halmstad, and 61 km south southwest of Varberg.

Fireball, Booms and Bright Lights in Nova Scotia (August 12) -
http://www.thecoastguard.ca/News/2012-08-13/article-3051435/Updated...
Several witnesses are describing an object with a fiery green tail that flew across the skyline. David Landry was in Dartmouth when he watched the bright object hurtle across the sky over the Halifax bridges and towards the west shortly after 11 a.m.
He said the object was “much bigger and closer” than any meteorite he had ever seen before.
Moments later people in western Nova Scotia reported hearing the booms and seeing flashes of light.
Shortly after 11 p.m. people from Liverpool to Yarmouth County and beyond reported seeing flashes of light and hearing booms. Some reported hearing two booms, a large boom followed by a smaller boom.
Unlike a lightning bolt, this flashing bluish light was reported to last for more than 30 seconds and the “thunder” was heard and felt for more than 100 miles.
No calls about the event were made to the rescue coordination centre in Halifax and there were no calls made to Shelburne RCMP, although several RCMP members reported hearing the boom.
Federal Natural Resources Department officials reported no seismic activity in the area, ruling out an earthquake as a potential source of the boom. Nova Scotia Power also reported no problems with its equipment in the area.

Event into space in Honduras on Wednesday, 22 August, 2012 at 03:02 (03:02 AM) UTC.
Specialists with the Permanent Contingency Commission (COPECO) are now in Trojes area, in the eastern Honduran department of El Paraíso, to investigate the alleged crash of a meteorite. According to the inhabitants of that region near the border with Nicaragua, a fireball crossed the sky on Saturday night and then they heard a loud explosion. A COPECO statement clarified that no specialized agency reported a meteorite passing by the Central American region, nor has reported the loss of an aircraft. Copeco and the astronomical observatory of the National Autonomous University of Honduras said their experts in the field are investigating what happened in that region and will report as soon as possible, while they called on people not to generate speculation to avoid uncertainty.

Mystery Boom In North Mississippi (August 21) -
http://www.wtva.com/news/local/story/In-search-of-a-mysterious-soun...
Monday morning there was a mysterious boom that was heard across parts of north Mississippi, and Tuesday, WTVA's Wayne Hereford went in search of some answers.
For a while we thought that we might have the answer, but the "big boom" mystery continues.
We still don't know for sure what caused the loud sound across north Mississippi Monday, but just like you told us on our Facebook page, the sound was real as we were able to confirm in two separate counties .
"We had a few calls reporting that they heard a loud explosion ,sound. And some that their houses shaking," said Paul Harkins, the director of Lee County Emergency E-911.
One man who lives in Itawamba County says he heard it too.
"Yesterday afternoon, I was out in the back yard. And then all of a sudden I heard this large boom. I don't know how to really describe it. It was like a sonic boom or something," said Al Smith of the Tilden Community.
We thought we might actually be on to something earlier Tuesday when we received an e-mail from the Monroe Gas Storage Area in Amory.
The letter explains that "seismic activity will be conducted for the purpose of exploring the lands for the presence of structures favorable for the storing of natural gas . It went on to say that activities may include land surveys, laying seismic recording devices, geophones on the ground, drilling of shallow shot holes,and the use of truck-mounted energy sources."
But a spokesman for Monroe Gas later told us that their crews have not even started on the process yet, and that they are only in the land acquisition phase of the seismic acquisition program.
Meanwhile at least one resident, who lives near the facility in Amory, says his entire house has been shaken in the past as if there were an earthquake.
Another Monroe County woman said she heard a loud noise Monday too, but assumed it was just a clap of thunder.
That company spokesman for Monroe Gas says there is no part of their seismic acquisition program as loud as what some in the area have described.
He did say that there are other companies performing drilling work in the area.

Source Of Loud Booms In California Foothills A Mystery (August 24) -
http://sacramento.cbslocal.com/2012/08/24/source-of-loud-boom-in-fo...
People from all over El Dorado County say they’re hearing loud booms several times a week, but there are many theories on what is causing them.
“I thought it was thunder,” said one person.
“It’s definitely not thunder; too consistent. I thought it was just mining,” said another person.
“I always considered them to be sonic booms from flying aircrafts for years,” said Loring Brunius, owner of Sierra Rock Diamond Quarry.
People who live near Pleasant Valley say their days have been interrupted by loud booms, shaking the floor beneath them.
“You can feel it in the ground, no question about it. But no one’s been able to figure out why,” said Pleasant Valley resident Peter O’Grady. “I tend to hear somewhere between four to six of these things during the weekdays usually between 11 p.m. and 2 p.m.
“Boom, boom, boom, boom just like that,” said Lorren Gonzales, who lives near Pleasant Valley.
And the rolling foothills of El Dorado County make it difficult for them to even tell where it’s coming from.
We asked the owner of Sierra Rock Diamond Quarry what he knew about it. He says they havent blasted since last year. And any miners or quarry owners would need government permission before they can set off any explosives.
“It’s a federally mandated system, and enforced,” said Brunius.
Some think the booms are from nearby wineries using propane cannons to scare away birds.
“We’ve never done it and I don’t know of any other winery that does,” said Carrie Bendick, a winemaker at Holly’s Hill Winery.
According to USGS, there aren’t enough seismic stations to pinpoint the exact location. Meanwhile, some say the booms have been around so long and happen so often they barely notice them anymore. Still, others want to solve the mystery.
“I would like to know what it is, yeah. And I’d like to know when it’s going to stop too,” said O’Grady.
CBS13 spoke to Fallon Naval Air Station that said any supersonic flight operations they do are only allowed over Dixie Valley, which is hundreds of miles away.
Some think illegal mining could be the source of the sounds, but Brunius doubts that theory. He said if that was the case, the culprit would have been caught by now.

Mystery Booms in Western India Since August 25 (Sept 8) -
http://www.indianexpress.com/news/mysterious-sounds-seismograph-ins...
A seismograph has been installed in this district's Jawhar taluka where mysterious underground sounds over the past two weeks have rattled the locals.
Additional Collector Ashok Shingare today said seismograph has been installed in the town in the wake of complaints from locals about the unexplained underground booms being reported since August 25.
Shingare said the administration had taken every step to instill confidence among the people of Jawhar, who are living in panic and fear.
Geology experts from Pune, Mumbai and officials from IIT-Bombay are camping in the taluka since the last two days to find out the cause of the mysterious sounds, he said.
No seismic activity has been reported from the area during the last fortnight, Met Department had said earlier. Shingare said the administration had also got in touch with the National Geo Physical Laboratory and sought their help in unravelling the mystery.
The administration has appealed, through CDs, to people not to panic, he said, adding intensity and frequency of the sounds had been coming down over the last few days.

Loud Noise and Shaking In Louisiana Near Infamous Sinkhole (Oct 3) -
http://www.dailycomet.com/article/20121004/ARTICLES/121009798
Nobody quite knows what caused the ground in some parts of Lafourche and Terrebonne parishes to shake, but it certainly has people talking.
A little before 2 p.m. Wednesday, reports began flooding in to officials of tremors accompanied by a loud noise. The Lafourche Parish Sheriff’s Office and Office of Emergency Preparedness received reports, but nobody has been able to narrow down a cause.
Lockport resident Bryan Comardelle had just sat down to watch television when he felt the rumble.
“It was just a sudden vibration,” Comardelle said. “I live in a brick house, and it even made it shake.”
Most reports are fairly uniform: one to four tremors reported in the southern reaches of the parishes all the way up into Raceland and Houma. Some people reported hearing a loud noise similar to thunder accompanying the rumbling.
“My wife described it as sounding like a garbage truck had just dropped a dumpster,” Comardelle said.
After the first rumble, Comardelle joined his perplexed neighbors outside looking for the rumbling culprit or any sign of bad weather that could have caused the thunderous noise.
“It was clear outside, and then we felt more tremors,” Comardelle said.
Chris Boudreaux, Lafourche’s director of Emergency Operations, spent Wednesday afternoon and Thursday morning making calls to try to narrow down the possible causes.
Boudreaux said the National Guard reported having no fly-overs that could have caused a sonic boom that follows a craft breaking the sound barrier. He also called multiple oil-field facilities, but none had an explanation.
“As far as right now, we haven’t found anything,” Boudreaux said. “I don’t think we will.”
Boudreaux also put a call into the U.S. Geological Survey, which monitors seismic activity. But it had nothing to report, though its closest monitors are in Assumption Parish and extreme west Terrebonne, Boudreaux said.
“Of course the sinkhole comes to mind,” said Raceland resident Lauren Matherne, who was sitting in her home with she felt the jolt.
Residents of the Assumption Parish community of Bayou Corne felt light tremors in the months leading up to the emergence of the 400 foot-wide sinkhole in the swamp near the community this past summer.
“It’s just strange. Of course, we are all concerned about what caused it,” Matherne said.

Mystery Booms Rattle New Jersey Community (Oct 5) -
http://www.nbcphiladelphia.com/news/local/Mystery-Blast-Rattles-NJ-...
Police in Manchester Township, NJ are investigating a mysterious boom that shook block after block in the Ocean County community Thursday night. Residents say it felt and sounded like an explosion.
“It was so loud that my windows were rattling" said Jayne Yereance. "I really thought the house next door blew up. That’s how bad it was.”
Residents say there have been similar incidents since the summer. Police are trying to determine if they're connected, but investigators don't yet know where the sounds are coming from or who is responsible.
There's been no damage and no one's been hurt, but many people are on edge.
"I really wish they would knock it off so we can stop jumping out of our skin” Marissa Bartles said.
The Lakehurst military base is nearby, but authorities don't think that's the source of the booms. Military officials tell NBC10 there were no explosions on the base Thursday night.

Mysterious Ground Shaking Continues in New Jersey (Oct 21) -
A mysterious ground shake through parts of southern New Jersey rattled residents around 11am this morning leaving bewildered residents still without answers.
Both the U.S. Geological Survey and the National Weather Service reported no earthquake having occurred in the area and the nearby military base claiming to have had no training exercises that would have caused the tremors.
The shake was reported in several counties including Atlantic, Cape May, Ocean, Salem and Camden.
'I'm in [Little Egg Harbor] and my basement door shook violently for 15 sec or so long enough to creep me out. Sounded like someone was trying to get out,' a resident wrote on the Facebook page for Jersey Shore Hurricane News.
'My dog whelped two times before it happened I had thought he hurt himself. Then the huge noise boomed and my house shook slightly. It felt like it came from above,' a claimed Northfield resident wrote.
Last weekend Joint Base McGuire-Dix-Lakehurst had advised residents of scheduled military training that could cause booms and ground tremors.
Base spokesman Pascual Flores told NBC News that wasn't the case for today.
'There currently is no training of any type that would have resulted in today's incident,' he said.

Another 'booming' earthquake - this time near Niagara Falls: Earthq...
A minor earthquake is being blamed for causing a loud boom noise that was heard and felt in Niagara County early Friday morning. The U-S Geological Survey is confirming a 2 point 5 magnitude earthquake just outside of Olcott before one A-M this morning. They speculate that low-depth earthquakes can cause a loud noise especially in the Northeast United State.
We received word from viewers early this morning who heard the loud sound they say felt like an explosion around 1 a.m. Friday in Barker, Somerset, Olcott, and Newfane. There were even reports of some residents in Canada hearing and feeling it. Some thought that it may have been caused by a plane at the Niagara Falls Air Base, but the Base tells us that they don't own any planes or equipment capable of creating a sonic boom. The FAA also confirms that there were no aircraft in the area around that time.

Mysterious loud boom heard & felt all over Tucson
TUCSON, AZ (Tucson News Now) -
Something caused some shaking, rattling, and rolling over many parts of Tucson Wednesday night. It happened about 7:45 p.m.
Tucson News Now was inundated with calls from people asking what it was. We made calls to several law enforcement agencies and Davis-Monthan Air Force Base. D-M says it was not one of their aircraft that caused a sonic boom.
Capt. Adam Goldberg from Northwest Fire District says all the area fire departments received about 100 calls. The Tucson Fire Department says most of their calls came from the west side of Tucson.
Tom Peine with the Pima County Sheriff's Department tweeted, "We checked with variety of places to include mines, DMAFB, Pinal Army Nat. Guard, TIA, SW Gas, El Paso Gas, TEP/So far all negative."

I heard "Earth Trumpet" sounds this morning 4/16/13 at 1am in Las Cruces NM although kind of hard to hear, it was unmistakable and also had a low rumble accompaning it, and it also came in waves, I feel it lasted about 15 minutes. I have been able to correlate it to earth movement on this Albuquerque heliplot for the same time. I do wonder about the origin since there is not much water here, other than underground.

Recurring Mystery Booms in Northern Ireland (Apr 27)
A mystery bang has left people scratching their heads in Londonderry.
For the third time in over a year, people have reported hearing a loud noise that, they said, sounded liked an explosion.
The Police Service of Northern Ireland (PSNI) said officers carried out searches in the early hours of Friday morning but nothing was found.
Dozens of people contacted the BBC to say they had heard the mystery noise.
The deputy first minister, Martin McGuinness, tweeted: "Loud explosion in Derry a few minutes ago, whatever caused it, hope there are no casualties".
A PSNI spokesman said: "Extensive police checks were carried out in the area by officers on the ground and the police helicopter was deployed but nothing was found.
"Police would ask members of the public to be vigilant. If they see any suspicious items do not touch or attempt to move them but call police immediately."
BBC Radio Foyle reporter, Sean O'Halloran, heard the noise.
"It was so loud that I was convinced it was an explosion," he said.
"Social media sites went into overdrive as people speculated about what it might have been.
"I came across a police checkpoint in the city centre. Officers told me they had received reports of a loud bang but hadn't found anything."
There have been two similar cases in Derry in the past.
Loud bang
In February, police investigated reports of a loud bang in the city centre but nothing was found.
In January 2012, homes and businesses were evacuated in the Spencer Road area. It was sealed off for a number of days but the police said there was no evidence of an explosion.
