El Salvador's San Miguel Volcano Erupts (Jun 18)

The San Miguel Volcano exploded violently on Saturday at 4:10am local time.

This new explosion covered the surrounding area with dust and was preceded by a sharp increase in seismic activity.

At the end of May 2016, seismograms started recording a very significant increase in tremors, most probably related to fluid circulation within the giant. The activity gradually declined until June 13 where again, 400 tremors were recorded and 500 the day after and another 500 on June 15.

This succession of seismicity peaks in June was accompanied by an increase in the amount of SO2 in the plume degassing.

Ash has been reported in villages around the volcano.

Degassing is still observed from the crater forming a plume about 400m high.

The last eruption of the San Miguel volcano occurred on December 29, 2013. It prompted the evacuation of thousands of people living in a 3 km radius around the volcano and was also preceded by increased seismic activity.

Philippines Mt Bulusan Volcano Explodes a Day After Mt Kanlaon  (Jun 19)

After a week of being silent, Mount Bulusan spewed ash on Sunday afternoon.

The explosion took place at around 1:03 in the afternoon. The explosion was steam-driven and created a 300-meter ash column above the crater.

The event lasted for about seven minutes based on the seismic record, drifting towards the northwest portion of the volcano.

Last week, the volcano exploded at 11:35 a.m., sending an ash column about 2,000 meters high.

This latest event comes only a day after the nearby Mt Kanlaon eruption yesterday.

Kanlaon and Bulusan are both active volcanoes that had a recent history of eruptions. They have not record however, of undergoing eruptions at the same time or one after the other.

A possible simultaneous eruption could put a stress on volunteer and government disaster management authorities and this early, President Benigno Aquino III has ordered the National Disaster Risk Reduction Management Council (NDRRMC) to closely monitor developments and prepare for the evacuation of people living in vulnerable areas if necessary.

“Field personnel are being mobilised to ensure the safety of the people. There are permanent exclusion zones being observed within a certain perimeter near the two volcanoes,” according to Philippines Institute of Volcanology and Seismology (Phivolcs), Presidential Communications Operations Office Secretary Herminio Coloma.

Volcanoes Erupt in Indonesia, Guatemala (Jul 1)

Sumatra's Sinabung volcano exploded twice on July 1, throwing a column of ash and gas to a height of 2500 meters above the crater. The volcano and its surroundings have been placed under the highest level of alert: IV.

The first eruption occured at around 1:00 pm local time. A second and more powerful eruption happened 4 hours later at 5:22 pm.

Mount Sinabung, which has been active since September 2013, has started to spew lava and ash clouds that have spread as far as 1,200 kilometers away from the crater, Meteorology, Climatology and Geophysics Agency (BMKG) deputy chairman Yunus Swarinoto said on Friday.

“People who live within a 4 to 6 kilometer radius of the mountain have to be evacuated to safe places,” Yunus said in a press statement.

The BMKG also warned people living near rivers to remain alert as the lava might also flow along rivers and spill out in downstream areas.

Guatemala's Santa Maria volcano also exploded strongly on July 1 for the second time in two days.

Ash and gas were ejected more than 5000 meters above the crater and may have caused ballistic expulsions up to 1 meter in diameter up to 3 kilometers from the dome.

Turrialba Volcano Made Tow New Eruptions Monday Morning; Two Sunday Night

"Romeros" are being recommended to wear facemasks given the increase in volcanic activity at the Turrialba

 http://qcostarica.com/turrialba-volcano-made-tow-new-eruptions-mond...

The Volcanological and Seismological Observatory of Costa Rica (OVSICORI) informed through his Facebook page, that at 7:22am the volcano had an eruption that reached a height of 3,000 metres above the summit. A second eruption was recorded at 8:26am, this time reaching only a height of 1,500 metres.

Sunday night two eruptions were recorded, the first at 9:23pm and the second at 10:17pm, reported the OVSICORI, with ashfall reported in area of Barva de Heredia and Poas in the Central Valley and also in Cartago.

In the Sunday night eruption, the winds scattered thea ashes in the direction of the Orosi Valley, Gerardo de Dota and Quepos, all southwest of the volcano.

The Monday morning eruptions are believed to be tied to an increase in volcanic tremors recorded starting at 11:00pm Sunday night.

Given the increased activity of the volcano, OVSICORI volcanologist Javier Pacheco, recommends “romeros” – the faithful making their pilgrimage to Cartago in this year’s celebration of Virgen de los Ángeles (Our Lady of the Angels) on August 2, wear facemasks – especially those suffering from respiratory ailments.

Powerful Eruption at Japan's Sakurajima Volcano (Jul 26)

Mount Sakurajima erupted with a massive column of ash rising over 3 miles high early Tuesday.

The eruption occurred at 12:02 a.m. at the mountain's Showa crater.

This is the first time that the active volcano in southern Kyushu has spewed out a smokestack that high since an eruption on Aug. 18, 2013, according to the Kagoshima Meteorological Office.

It marked the 47th eruption this year, and the observatory is warning residents and travelers in the area that traffic accidents may occur because of the falling ash.

The Japan Meteorological Agency continues to keep Sakurajima on an alert level of “3,” which closes off the entire mountain except for residential areas along the coast. It has been at that level since February.

Clouds of ash cover the skies over Indonesia: Flights are disrupted as THREE volcanoes erupt in just three days

http://www.dailymail.co.uk/sciencetech/article-3721081/Eruptions-3-...

Giant clouds of ash engulfed the skies as Mount Sinabung became the third volcano to erupt in Indonesia, in the space of just three days.

Mount Rinjani on Lombok island near Bali erupted on Monday, with the Sinabung volcano on Sumatra island and Mount Gamalama in the Moluccas chain of islands following suit late yesterday.
No one has been injured but flights at two airports have been disrupted.

The eruptions darkened skies in parts of the archipelago and disrupted some flights.
Sutopo Purwo Nugroho, the spokesman for Indonesia's Disaster Mitigation Agency, said that Gamalama and Sinabung erupted late yesterday, blasting debris high into the air.
'People are advised to stay calm,' said Sutopo Purwo Nugroho, adding authorities were not yet planning evacuations.
Nugroho said farms and trees around the three volcanoes were covered in gray ash, but nearby towns and villages were not in danger.
Hot ash tumbled down the Sinabung slopes as far as 2,000 metres (6,562 feet) southward into a river.
The volcano has been put on alert its highest level since June 2015 following a significant increase in activity.

Highest volcano in Eurasia spews ash 7.5 kilometres in the air

Satellite images show the ash column spiralling to 7.5 km above sea level, said the Geological Service in Kamchatka.

'Ash is carried to the north-east. The concrete size of the ash plume is unknown since a large area near the volcano is covered in thick clouds,' said a statement.

So far there are no reports about volcanic ash eruptions in settlements of the Ust-Kamchatsky district, where the volcano is located.

The Klyuchevskoy, also called Klyuchevskaya Sopka, is located 360 km north-west of regional capital Petropavlovsk-Kamchatsky in the extreme east of Russia.

The nearest town, Klyuchi, is home to about 5,000 people. The volcano rises 4,750 metres above sea level.

It is one of 29 active volcanoes on the Kamchatka peninsula.

Second eruption in last seven days.

Klyuchevskoy volcano in Russia's Far East sends ash seven kilometers high

PETROPAVLOVSK-KAMCHATSKY, 10 August (BelTA - TASS) - Klyuchevskoy volcano on the Kamchatka Peninsula in the Russian Far East has spewed ash up to seven kilometers into the sky, the Kamchatka Volcanic Response Team (KVERT) told Tass on Wednesday. "The volcano continues erupting. The ash plume has spread 264 kilometers east and southeast of the volcano," its source said. An ‘orange' aviation alert code has been assigned to the volcano, second after the highest - red code, warning about the hazard eruptions may pose to aircraft flying on local and international routes. No ash fall has been registered in settlements of the region, the Kamchatka department of the Russian Ministry for Emergency Situations reports.

Shiveluch (Kamchatka): The activity of the volcano remains essentially unchanged. Part of the dome collapsed yesterday morning and generated a pyroclastic flow that traveled down the SW valley. The flow reached approx. 1500 m length and was 300-400 m wide. A second flow of similar size occurred immediately after. The resulting ash plume rose approx. 1 km.

Suwanose-jima (Ryukyu Islands): The volcano's activity has picked up again. Since yesterday, webcam images show constant red glow and intense degassing as well as intermittent ash emissions some of which have also been reported by Tokyo VAAC. Most likely, a new phase of intense strombolian activity is currently taking place at the active O-Take crater on the remote island.

Dukono (Halmahera): Continuous ash emissions have been observed during the past days. Satellite images show a plume extending into various directions (to the east today). In short, the intense activity of the volcano observed also during recent visits by various people seems to continue.

Yasur (Tanna Island, Vanuatu): Wellington VAAC reports ash plumes, mostly confined to Tanna Island, visible on satellite imagery today. This suggests that activity at the volcano is elevated at the moment. Volcanic explosions remain intense, volcanic bombs may fall in and/or around the crater and volcanic gas and ashes can also affect some villages.

Aoba (Vanuatu): Wellington VAAC received a pilot report of plumes of white steam and ash rising 1000 ft (300 m) above the active crater lake Voui this morning. The remote location of the volcano's large caldera and its extremely difficult make direct observations very rare. According to GeoHazard, "Aoba probably should be considered at present times as the most dangerous volcano of the archipelago, due to the presence of a large lava lake in the main crater." Strong explosive eruptions have been frequent in the past, generating dangerous mud flows that left thick lahar deposits in the central part of Ambae island and up to the coastlines.

Colima (Western Mexico): The volcano's activity seems to have picked up.. Several explosions occurred today, producing ash plumes that rose to up to 14-18,000 ft (4-6 km) altitude and dispersed into westerly directions. During intervals between eruptions, degassing is visible from several vents inside the summit crater where a  lava dome is likely continuing to grow.


Popocatépetl (Central Mexico): The volcano's activity has been essentially unchanged over the past week. On average, 2-4 explosions have been occurring daily - mostly small events with plumes less than 1 km tall - and about 50-100 pulses of steam emissions ("exhalations").  Glow at night visible from the crater indicates that magma continues to slowly rise and accumulate there.

Santiaguito (Guatemala): The series of strong vulcanian explosions continues. This morning, another one occurred that produced a mushroom-shaped eruption column that rose to approx. 18,000 ft (6 km) altitude. Partially collapsing parts of the eruption column generated moderately large pyroclastic flows on the eastern side and perhaps on the SW slope of the lava dome as well. Ash falls have occurred in nearby towns and villages such as San Felipe and Mazatenango Retalulehu.

Powerful Explosion at Guatemala's Santa Maria (Santiaguito) Volcano (Aug 16)

A particularly strong explosion occurred this morning sending a massive mushroom-shaped ash plume that reached 20,000 ft. The  immediate surroundings were showered by volcanic blocks and bombs, and collapsing material from the eruption produced avalanches that engulfed the cone on several sides (pyroclastic flows).

The ash plume drifted to the WNW and caused significant ash falls in areas as far as the border with Mexico (e.g. Cacahotàn, 75 km distance). Light ash fall was even recorded in greater distances, e.g. the Mexican town of ​​Soconusco in 145 km distance.

The eruption came bare 48 hours after the previous one on Sunday. It can well be that the volcano is currently entering a phase of particularly increased activity.

Mt. Sinabung spewed ash 86 times Thursday.
Island focus: Residents told to stay away from Sinabung
http://www.thejakartapost.com/news/2016/08/27/island-focus-resident...
The local disaster mitigation agency has warned people living in the vicinity of Mount Sinabung to find safe places because of the danger of hot ash from recent volcanic activities.
On Thursday, Mt. Sinabung spewed ash, leaving hundreds of houses in the districts of Simpang Empat, Berastagi and Dolatrayat covered in volcanic debris.
The three districts are located far to the east of the volcano.
Mt. Sinabung also spewed hot ash the day before.
Igan Sutawidjaja, a researcher with the Volcanology and Geologic Disaster Mitigation Center (PVMBG), said the volcano spewed hot ash 86 times on Thursday.
He predicted the volcano would spew more hot ash in the new few days, most probably to locations east of it.
“The possible direction of the hot ash can be seen from the position of the crater,” he said on Thursday.
Therefore, it is dangerous for people to undertake activities in the vicinity during a volcanic eruption, he added.
Meanwhile, Karo Disaster Mitigation Agency (BNPD) official Natanael Perangin-angin said his office strengthened coordination with other institutions in anticipation of potential large-scale eruptions in the coming days.
“We have had coordination meetings with villages surrounding Mt. Sinabung to keep a distance from the ‘red zone’,” Natanael said.
He added the areas included in the danger zone are those within a 3-kilometer radius from the peak of the mountain, 7 km to the south-southeast, 6 km to the southeast-east and 4 km to the northeast.

Soon to Blow? Iceland’s Katla Volcano Rattled By Unusually Strong Earthquakes

30.08.2016

http://sputniknews.com/europe/20160830/1044756491/iceland-katla-vol...

Katla, one of Iceland's largest volcanoes, was rocked by two abnormally strong earthquakes Monday morning, raising concerns that the volcano may soon erupt.

The southern-Iceland volcano has not erupted since 1918, and scientists believe that a violent release is long overdu

In the early hours on Monday the area was hit by magnitude 4.5 and 4.6 quakes, similar to movements it experienced in 2011.

The nearby Eyjafjallajokull volcano erupted in 2010, creating so much dense ash that it shut down a large area of airspace for nearly a week.
Interestingly, the volcano is covered by a large icecap, which would likely delay the eruption for around 60 to 90 minutes, according to Roberts. The delay could give people time to evacuate and assist air traffic control in redirecting aircraft. The ice cap itself presents hazards, though. “The other hazard might be a jökulhlaup, or glacial outburst flood. Melting from the summer within the Myrdalsjökull icecap and that meltwater can accumulate until it spills over as a flood of water, ice, and debris. These have occurred often and do not need to be associated with any volcanic activity,” Wired explained.

A very superficial seismic swarm was detected yesterday afternoon at Campi Flegrei: starting at 16:22 (local time) on August 29, 2016, explains the Vesuvius Observatory, "it was recorded a swarm of 40 events in the area of Campi Flegrei. The major energy event, recorded at 17:45, had a magnitude of 1.7. The area affected by the swarm is to Pisciarelli-Solfatara. The depth of the events is approximately 1 km below the sea level. The last event (instrumental) of the swarm was recorded at 18:27 ".

The population, in the afternoon, in the upper area of ​​Pozzuoli near the Solfatara volcano, warned both the roar is the vibration of the ground.

There are no connections to the earthquake in central Italy, as, announces the Vesuvius Observatory, the seismic swarm was caused by a volcanic phenomenon, namely the lifting of the ground (bradisismo) in place at Campi Flegrei.

At the moment is in place a phase of lifting of a few millimeters per year. The most relevant event was recorded last October with a swarm of over center shook with maximum magnitude of 2.3, the occasion felt directly by the people

Turrialba Volcano Closes Costa Rica Airports (Sep 19)

Two of Costa Rica's airports were closed after Turrialba volcano erupted twice on Monday, sending incandescent rocks and thick ash into the sky.

The first eruption occurred at 2:53 a.m. and lasted about 15 minutes. The explosion launched ashes, gases and incandescent rocks into the air to about 1,000 meters (3,280 feet) above the volcano’s crater, UNA’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported.

The second  explosion occurred at 11:32 a.m. and spewed material about 13,000 feet into the air, the agency said.

OVSICORI volcanologist María Martínez said that after the second explosion, reports were received of ash falling in communities north and west of San José, including Coronado, Moravia, Tibás, Guadalupe, Escazú and as far away as Alajuela province.

Operations at the Juan Santamaria International Airport, the country’s main air terminal, and the Tobias Bolanos airport, were suspended until conditions improve, according to the chief of the Civil Aviation Directorate Ennio Cubillo.

Authorities also considered whether to limit the general aviation activities at the Daniel Oduber International Airport located in the northwest of the Central American nation.

Costa Rica's Turrialba Volcano Eruptions Continue (Sep 22)

Over the past few days, Turrialba has had over 20 significant, ash-rich explosions that have ended up closing airports across the country.

The latest eruption on Sep 22 remained constant for nearly 4 hours, spewing ash, gas and vapor almost 3,000 meters (some 9,800 feet) above the crater.

The National University’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) reported that wind conditions prompted ash to reach northern areas of Heredia and Alajuela provinces. 

Ash also reached the Braulio Carrillo National Park, Guápiles and other communities in the Caribbean province of Limón.

Multiple Eruptions at Guatemala's Fuego Volcano (Sep 27)

A series of eruptions at Guatemala's Fuego volcano spewed lava and sent ash raining down near the capital.

The volcano is maintaining "moderate to heavy explosions," according to the National Institute of Seismology, Volcanology, Meteorology and Hydrology.

The eruptions have sent an ash column up into the sky, reaching about 5,000 meters (16,400 feet) above sea level. The column is moving more than 20 kilometers (12 miles) westwards and southwest.

The rumbling 3,763-meter-high volcano is located 45 kilometers southwest of the capital Guatemala City. The incandescent lava at the top of the crater is feeding two rivers of lava.

The falling ash is affecting a number of communities, especially the town of Yepocapa, near the volcano.

The institute recommended that aviation authorities take precautions with air-traffic control.

Costa Rica's Turrialba Volcano Spews Ash for 5th Consecutive Day (Sep 30) 

Turrialba Volcano continued spewing ash and gases on Thursday in one of its longest eruptive events this year.

The ash spewing at Turrialba, located some 50 kilometers (30 miles) northeast of the capital San José in Cartago province, began shortly after noon on Monday. Ash and vapor formed a column that varies in height from 500 meters to 2,000 meters (1,640 feet to 6,560 feet) above the crater, RSN reported.

Eruptions at Turrialba last week caused the Juan Santamaría International Airport in Alajuela, outside of San José, to close for nearly 24 hours. The airport has remained open this week although some flights were delayed Thursday morning.

The National Meteorological Institute reported that wind is currently carrying ash mainly towards the northern areas of the Central Valley.

On Thursday, RSN received reports on its social media profiles of persistent ashfall in communities in the northern parts of Cartago, San José, Heredia and Alajuela provinces.

The National University’s Volcanological and Seismological Observatory of Costa Rica (OVSICORI) also noted that some people are reporting ashfall in various areas of the Caribbean province of Limón, mostly in Guápiles.

In addition to ashfall, people said they smelled sulfur in the air north and east of the capital, in Coronado, Moravia, Tibás, Zapote, Curridabat and Montes de Oca, and also in Cartago and Heredia provinces.

Violent Eruption at Mexico's Colima Volcano Forces Evacuations (Sep 30)

Streams of lava and large plumes of ash emitted in a dramatic volcanic eruption has forced residents in the state of Colima, Mexico to leave their homes.

Over 300 people were ordered to evacuate villages in the foothills of Volcan de Fuego, the 3,839-meter mountain which towers over the states of Jalisco and Colima.

Late Friday, Colima State Governor Jose Ignacio Peralta ordered people to evacuate from the nearby villages of La Becerrera and La Yerbabuena because of lava and noxious gases being emitted by the volcano.

Members of the National Civil Protection, Mexico’s Army and the State Civil Protection Unit have been deployed to transport residents to emergency hostels away from the danger.

People are also being warned to stay away from rivers and ravines close to the volcano, for fear the lava could take a path of least resistance and rush downhill.

TOKYO - Mount Aso in southern Japan sent huge plumes of gray smoke as high as 11 kilometers (6.8 miles) into the air on Saturday in one of the volcano's biggest explosions in years.

Mount Aso has sent huge plumes of gray smoke as high as 11 kilometers (6.8 miles) into the air in one of the volcano's biggest explosions in years. Kyodo News via AP Hiroko Harima

The Japan Meteorological Agency said the explosion in the early hours of Saturday also blew off bits of volcanic rock and ash and raised the alert level for the area, extending the entry ban from just around the volcanic mouth to the mountain itself.

Footage on Japan's NHK public television showed orange flames flickering from several locations on the mountaintop as the volcano emitted thick gray smoke billowing into the sky.

There are no homes within the off-limit area and no injuries or major damage have been reported in nearby towns, though buildings and cars were covered with thick ash falls. Flights were largely unaffected, except for some delays.

A window at a youth center just a few kilometers (miles) away from the mountain suffered a crack apparently from volcanic rocks.

Masaaki Yamamoto, a manager at the center, told NHK that he heard small volcanic rocks hitting the exterior of the building, and found a crack in the window along with chunks of volcanic debris about the size of a golf ball near it.

Aso city, about 10 kilometers (6 miles) north of the volcano, set up evacuation centers as a precaution. Residents were washing off ash from external walls, plants and the streets before it dries up and spreads farther. Media reports said some ash falls were detected in parts of western Japan.

The area is still recovering from deadly earthquakes in April.

Mount Aso has repeated smaller eruptions in recent years. The agency said it was not known if the volano's recent activity was related to the earthquakes earlier this year, but it's in an unstable condition and could erupt again.

Japan sits atop the Pacific "ring of fire" and has more than 100 volcanoes.

Mount Aso had a smaller eruption in August while eruptions in 2014 disrupted tourism in the area.

http://www.andnowuknow.com/headlines/colombias-nevado-del-ruiz-volc...

The Nevado Del Ruiz Volcano, located about 80 miles west of Colombian capital Bogota, sent plumes of ash and gas into the air this last weekend, putting locals on alert.

The eruption is the latest of two weeks of activity, according to news source KRIS TV, which reported that emissions shot as high as 23,000 feet.

Officials from the Red Cross announced caution, commenting that those in the area need to be prepared in case the activity presents any danger.

As we have previously reported, the notorious volcano’s most recent activity were two consecutive eruptions in May, one with emissions reaching over 4,000 feet above the the peak, another over 7,500 feet.

While that last explosion resulted in the closure of two airports, there has not yet been any details of transport issues yet linked with last weekend’s activity.

The volcanic activity was also linked to a sizeable earthquake, according to El Espectador. The 3.1 magnitude tremor hit Sunday afternoon and was felt throughout Caldas to Manizales.

"The Nevado del Ruiz volcano continues to evolve and it is possible that new events that may indicate an acceleration of the process are presented, involving greater instability thereof and consequently changes in your activity level," commented the Colombian Geological Service.

AndNowUKnow will continue to track this and other natural occurrences that could affect the produce industry.

As Bulusan erupts a 3rd time, ashfall threatens residents’ health
http://newsinfo.inquirer.net/830176/bulusan-ashfall-threatens-crops...

          Ash blots out the sun in the village of Inlagadian in Casiguran town, Sorsogon province, following ashfall from Mt.    

          Bulusan on Oct. 21. —MARC ALVIC ESPLANA/Philippine Daily Inquirer

BULUSAN, Sorsogon—Thrice during the past week, Mount Bulusan in Sorsogon belched out gray ash plumes in a series of minor phreatic (steam-driven) eruptions that sent ash raining over villages in the towns of Bulusan, Casiguran and Irosin, threatening crops and endangering the health of some residents.

Antonio Banares, 64, a resident of Barangay Central in Bulusan town near the slope of the volcano said he thought the ash falling from the sky last week was just drizzle.

“I became aware that it was ash and that the volcano had a (minor phreatic) eruption. I saw the ash thicken and I thought, this is bad, especially for my heart condition,” he said.

Banares and other residents in 11 barangays in Bulusan had been suffering from the effects of phreatic eruptions on Oct. 17, 19 and 21.
The Municipal Disaster Risk Reduction and Management Council (MDRRMC) of Bulusan said the villages of Dancalan,

Madlawon, Poctol, Sapngan, Dapdap, Looban, Central, Sabang, Mabuhay, San Rafael and San Bernardo bore the brunt of

the ashfall which dumped up to half a millimeter thick of ash.

Fumes coming from the volcano drifted to the villages of San Jose and San Francisco.

The Philippine Institute of Volcanology and Seismology (Phivolcs) also found small traces of ashfall in the upland barangays

of San Rafael and Sabang in Irosin town during the Oct. 19 eruptions

In Casiguran town, Luisito Mendoza, the town’s MDRRMC officer, said at least 350 houses were covered by ash in

Barangay Inlagadian from the Oct. 21 eruption.

At least 10 residents were treated for vomiting and stomach ache, said Mendoza. Masks were also distributed to residents.
He said “if the situation gets worse,” officials would order preemptive evacuation.

Nerma Ricero, principal of Inlagadian Elementary School, canceled classes Friday after 310 students reported difficulty in

concentrating on their lessons. Bulusan Mayor Mike Guysayko also ordered classes suspended in eight elementary and

secondary schools.

Farmer Salvador Hajas, 33, said the continued eruption of Bulusan volcano is destroying crops. “Our produce are affected.

They get rotten due to ash,” he said.

Renard Fullon Garados, MDRMMC officer in Bulusan town, said officials are conducting an inventory of households that

need to be moved to safer grounds..."

PERU: PERU'S SABANCAYA VOLCANO HAS FIRST MAJOR ERUPTION IN A DECADE NOVEMBER 06

Sabancaya volcano had its first major eruption in more than a decade on Sunday, November 6. The volcano, which is located in Peru?s southern Arequipa region, continued to emit clouds of ash and steam on Monday.

Poasted Nov 11, 2016 - Two volcanoes, Sabancaya and Ubinas, erupt simultaneously in Peru – A first time for the country

http://strangesounds.org/2016/11/two-volcanoes-erupt-simulteneously...

Sabancaya and Ubinas volcanoes are separated by a distance of 100 kilometers, have different magma chambers, but they are erupting simultaneously right now! What a rare coincidence!

Both volcanoes are sending large volcanic cloud of ash and gas and show an enhanced seismic activity. Impressive explosions occur about every 4 hours, but every 15 minutes a small explosion occurs.

Sabancaya Ubinas and are separated by a distance of 100 kilometers. According to volcanologists, they have different magma chambers and currently simultaneous eruptions. A rare coincidence!

sabancaya began erupting 4 days ago (Nov 6) for the first time in 18 years. Ubinas is active since 2013 and has constant explosive phases.

As explained by Orlando Macedo, the director of the Geophysical Institute of Arequipa: “We are witnessing the simultaneous activity of two volcanoes right now! A first time for Peru. According to our data, this will continue.”

The volcano Zhupanovsky recorded two powerful explosions within 20 minutes on November 20, 2016.

The first eruption occurred at 14:29 local time, sending the ash and gas plume to an amazing height of 8 kilometers above sea level. The second ejection, 20 minutes later, sent ash up to 6.5 kilometers asl.

The Zhupanovsky Volcano in Kamchatka recorded to strong explosions on November 20, 2016, ejecting a column of ash to a height of 8 kilometers and 6.5 kilometers, respectively.

The first ash plume spread in a northeasterly direction, while the second was blown away in an easterly direction. Ashfall has been reported in settlements around the volcano.

Officials changed the level of Code Aviation danger to orange (high) and recommends tourist organizations not to conduct tours around the volcano.

Last time the volcano erupted was March 25th. Then the height of the ash column was eight kilometers. According to the Institute of Volcanology and Seismology (KVERT), all known volcanic eruption at Zhupanovsky were relatively weak and did not pose a threat for the surrounding populations.

The Zhupanovsky Volcano is a volcanic massif, consisting of four overlapping stratovolcanoes, located in the southeastern part of Kamchatka Peninsula, Russia. After 54 years of inactivity, the volcano began erupting on October 23, 2013, in 2014, and continuing nonstop into 2016.

Several moderate to strong explosions have been reported on November 20, 2016 at Fuego volcano in Guatemala

Loud rumbling noises! The resulting column of ash and gas reached 5 km above the volcanic peak, is dispersing towards S and SO over an area of more than 15km.

Ashfall was reported in Morelia, Santa Sofia and Panimaché. No evacuations are underway.

The rumbling noises produced by each loud explosions were heard several kilometers away.

Pyroclastic flows have also been observed descending along the side of the volcano in the Ceniza and Trinidad canyons.

It’s not just the Fuego volcano that shows an enhanced volcanic activity, it’s all around the world since the deadly New

Zealand earthquake!

Strong Explosion at Mexico's Popocatepetl Volcano (Nov 25)

An unusually long and strong explosion occurred on 25 Nov 2016 starting from 10:47 local time.

A continuous jet of steam, gas, and fragmented volcanic material which lasted about 20 minutes rising 3 miles.

The dramatic eruption spewed ash over the nearby city of Atlixco Puebla.

During the previous 24 hours, there were 324 volcanic eruptions.

Increasing Explosions at Peru's Sabancaya Volcano (Nov 28)

Sabancaya volcano in southern Peru continues to produce frequent explosions and now emits a continuous dense steam plume. Over the past weeks, activity has been gradually increasing.

Explosions are more frequent and stronger with plumes now regularly reaching more than 4000 m (2.5 miles) in height.

Peru's Geophysical Institute IGP reported 279 explosions during 14-21 Nov, a slow increase in SO2 emissions (up to 7000 tons/day) and some deformation of the volcano's SE flank, likely a result of a rising body of magma.

Increasing Explosive Activity at Mexico's Colima Volcano (Dec 10)

Explosions are more frequent and increasing in size at the volcano in recent days.

Vulcanian explosions at rates of 1-3 per hour are producing 3,000 meter ash plumes that eject incandescent bombs onto the upper flanks of the volcano.

The active lava flow continues to creep down the southern flank along with incandescent rockfalls, alimented by the growing lava dome in the summit crater,

The arrival of gas-rich magma seems to manifest itself in this new phase of increased explosive activity, which likely will destroy the current dome.

Mount St. Helens shakes 120 times within a week as volcano recharges, scientists say

http://www.seattletimes.com/seattle-news/northwest/mount-st-helens-...

In less than a week, four swarms of more than 120 earthquakes shook Mount St. Helens in late November. Although they were too small to be felt even by someone standing directly over their epicenters, scientists say they reveal the volcano is likely recharging.

“Each of these little earthquakes is a clue and a reminder we are marching toward an eruption someday,” said Weston Thelen, a U.S. Geological Survey seismologist with the Cascades Volcano Observatory in Vancouver.

However, “there’s nothing in this little modest seismicity, and none since 2008, that is a really good indicator of when that eruption will be.”

The earthquakes occurred between 1 and 2 miles below the surface and most registered at magnitudes of 0.3 or less; the largest was a magnitude 0.5. While the quakes are too small for human perception, scientists are able to study them thanks to sensitive seismometers stationed around the mountain.

As magma comes into the volcano’s system and is stored, scientists think that it releases gases and fluids that travel up into cracks, pressurizing and lubricating them, and causing small quakes.

“We know Mount St. Helens is slowly repressurizing. We can’t see it, but we think it’s inflating subtly,” said Liz Westby, a Cascades Volcano Observatory geologist.

Indeed, USGS scientists haven’t detected any anomalous gases or increases in ground inflation since the earthquake swarm.

“St. Helens is a well-behaved volcano, as far as we can tell,” Thelen said.

Westby said researchers have seen these kinds of earthquake swarms before.

Similar seismic episodes occurred during recharge periods between 1986 and the 2004 eruption; the small earthquake clusters resumed shortly after the eruption ended in 2008 and have continued periodically. Most recently, swarm earthquakes were detected in March through May of this year.

Scientists don’t exactly know how the volcano’s plumbing is laid out, but the little earthquake clusters give them a slightly clearer picture of what’s happening beneath the surface. By measuring how the speed of the seismic waves change as they move through the earth, researchers can better understand rock densities and where magma chambers are.

“These quakes don’t happen very often; you have to really exploit the ones we do get,” Westby said. “(It) gives us a better understanding of what’s going on and tells us where we need to do more research.”

Long Dormant Chilean Volcanic Complex Reawakens (Dec 13)

A "unique" burst of activity at a little-known volcanic complex near the Chile-Argentina border has attracted the interest of international scientists and led worried governments to plan for a potentially devastating eruption.

The volcanic field at the Laguna del Maule, located in central Chile near the Argentine border, has risen around two meters (6.5 feet) since 2007, undergoing "uplift" at a rate and consistency that is unprecedented in recent history, scientists said.

That likely means magma is exerting pressure on the Earth's crust in a zone where evidence indicates that explosive eruptions have happened repeatedly in the last few thousand years, though none in modern times.

If such an eruption were to happen at Maule today, it would have the potential to devastate nearby hydroelectric projects, and pump out ash that could wipe out crops across Argentina's pampas and severely disrupt global air traffic.

"We have so little experience with this kind of data, but the uplift is the biggest seen anywhere on the planet," said Bradley Singer, a geoscientist from the U.S. University of Wisconsin-Madison, who is leading an international research effort to understand what is happening under the surface.

"No-one has a seen a signal this large and this persistent. And it's in an area with an explosive record."

Scientists emphasize that it is impossible to know if or when Maule will blow again and how large any eruption would be.

Argentina and Chile have been working increasingly closely on monitoring the Andes volcanic chain that runs down their shared border. Most of the volcanoes - some 15 percent of the world's total - are located on the Chilean side, but winds usually mean Argentina faces the brunt of any ash cloud.

High in the remote Andes, the Laguna del Maule complex is centered around a deceptively calm, intensely blue lake of the same name, surrounded by arid volcanic rock.

The nearest towns are San Clemente in Chile, around 122 kilometers (76 miles) away, and the slightly closer Malargue on the Argentine side. Chile's capital Santiago is some 300 kilometers to the north.

About 2,400 people live or work in the nearby area, and the Maule river valley supplies around 25 percent of Chile's energy via 14 hydroelectric stations.

One of the people who knows the zone best is Raul Torres, an official who has lived close to the lake for around 60 years.

"About 10 or 15 years ago I noticed a real change in the area," he said, noting that the icy water temperature has warmed, algae have bloomed, and bubbles have appeared on the lake surface."

Volcano eruption in Aleutian Islands sparks aviation alert

http://www.abc.net.au/news/2016-12-21/volcano-eruption-in-aleutian-...

The Alaska Volcano Observatory has issued its highest level of alert for aviation after what it says was a brief eruption of a volcano on the Aleutian Islands.

The observatory said pilots reported the Bogoslof volcano on Bogoslof Island erupted about 4:00pm Alaska time.

Escalating Activity at Alaska's Bogoslof Volcano (Dec 23)

On December 21, a strong explosion produced an ash plume that showed up on satellite data and was observed by pilots in the area. According to this data, an ash column rose to approx. 10 km altitude and quickly dissipated to the south.

On December 22, another powerful explosion occurred at the volcano at 17:20 local time.

This second eruption was much stronger and richer in ash than the first one detected the night before.

It produced a relatively large ash plume that rose to 35,000 ft (12 km) altitude and drifted NE at 40 knots. The aviation color code was immediately raised to red; this plume was very dangerous for aircraft in the area who should now avoid the vicinity of the island.

Satellite data shows the plume clearly:

The December 22 eruption originated from a partially submerged vent and had a major impact on the morphology of the island itself.

A new, small island has formed just offshore of the northeast end of the main island. The former shore and much of the northeast side of Bogoslof Island adjacent to this island has been largely removed, and deposition of material has occurred on the west side of the island. The excavated area of the former northeast shore is likely the vent for this recent eruption, which appears to be just below sea level.

Analysis of shoreline change and vent location from the eruption of Bogoslof volcano. The base image was collected on March 19, 2015 and the analysis was conducted on data from December 22, 2016 after the large explosive eruption on December 21, 2016. Note that the location of the vent for the eruption was underwater or near the shoreline on the NE part of Bogoslof Island. Deposits have enlarged portions of the island and are interpreted to be comprised of coarse-grained volcanic ash and blocks of lava.

On December 23, another explosive eruption occurred at the volcano at around 09:30 local time. The alert level of Bogoslof was raised back to red.

A Coast Guard ship in the vicinity reported ash emission as well as ejection of lava and fragmental material. The eruption cloud did not penetrate the regional cloud tops at 30,000 ft and winds are to the north-northeast. According to the Coast Guard, ash emission subsided at about 10:37 AKST (19:37 UTC). On the basis of this information, the Aviation Color Code is raised to RED and the Alert Level to WARNING.

There is no monitoring of the volcano on the remote island itself and not much is known about its activity and typical behavior.

The last known eruption of Bogoslof volcano was in 1992 near the northern shore of the small island. A vent breached the sea surface producing surtseyan activity before building a new lava dome that eventually reached about 150 m height. Similar events had also occurred in 1927 and 1786, but only small remnants of the edifices produced by those earlier eruptions have survived the erosive action of the arctic ocean.

Peru’s Sabancaya Volcano Roars to Life (Dec 26)

Peru's Sabancaya volcano rumbled back to life on Monday, spewing ash and smoke some 11,500 feet into the sky, covering a radius over 30 kilometres, in the latest of a series of explosions.

The local authorities warned surrounding communities could be affected by ash from the volcano, which erupted at 8.24am local time.

The volcano had similar explosions on Dec 16  when it sent a plume of smoke 2,500 metres into the sky.

Mexico's Colima Volcano Erupts, 1.5 Mile Ash Plume (Dec 27)

Mexican authorities have set up exclusion zones surrounding the Colima volcano following increased volcanic activity.

An eruption early Tuesday created an ash plume about 1.5 miles tall with the possibility of ash falling up to 30 miles away from the volcano.

Authorities have also declared an exclusion zone in neighboring Jalisco state.

"Respect the radius of exclusion of 4.6 miles in Jalisco and 7.4 miles in Colima," the Interior Ministry said in a statement.

The Interior Ministry said ash will mostly affect areas east and west of the volcano, while areas within about three miles of the volcano are at risk of falling volcanic debris.

Alaska's Bogoslof Volcano Under High Alert After Another Eruption (Dec 26)

The Aleutian Islands' Bogoslof volcano is again under the highest alert level after another eruption on Monday producing a 30,000-ft ash cloud.

Temperatures recorded on cloud tops suggested an ash cloud that reached 30,000 feet.

Lightning and seismic data signaled the eruption.

The volcano erupted three times last week, with one ash cloud reaching 35,000 feet.

The Alaska Volcano Observatory posted a Monday afternoon update raising the alert level to "warning" for Bogoslof, about 60 miles west of Unalaska, and its aviation color code to red. Seismic data and satellite images showed an "ash-producing eruption" and cloud at the volcano just after 2 p.m. Monday, following at least three last week that reshaped much of low-lying Bogoslof Island.

In an update posted at 3 a.m. Tuesday, the National Weather Service's Alaska Aviation Weather Unit said that volcanic ash from Bogoslof was no longer visible on satellite images.

Major Explosions Continue at Alaska's Bogoslof Volcano (Jan 4)

Another major explosion occurred at the volcano today producing an ash plume that reached 33,000 ft. The Alaska Volcano Observatory reported a strong volcanic seismic signal from volcano starting at 21:18 local time January 3 and lasting  approximately 5 minutes. In addition, a series of lightning strikes were identified by the World Wide Lightning Location Network.

On December 31, the 6th major explosion during the current eruption cycle was recorded. The Alaska Volcano Observatory detected a strong seismic signal (captured on neighboring islands) and a swarm of lightning strikes typical for large eruption ash plumes near the volcano and extending north.  Weather cloud tops at 30,000 ft prevented visual and other satellite confirmation. That eruption started presumably at 22:30 local time.

Another relatively large ash-producing explosive occurred on December 30 at 23:45 local time. The eruption was inferred from seismic data on nearby islands and seen in recent satellite images. The resulting ash plume was estimated to reach around 20,000 ft altitude and drifting NE.

Earthquake triggers strong eruption at Sinabung volcano in Indonesia – lahar alert

http://strangesounds.org/2017/01/earthquake-triggers-strong-eruptio...

A strong explosion was recorded at Sinabung volcano on January 9, 2017.

It was triggered by a volcanic earthquake that occurred about 8 minutes before.

Ongoing Eruptions at Bogoslof Volcano Transform Island (Jan 10)

Alaska's remote Bogoslof volcano keeps erupting, and has demolished much of its Aleutian island home with a string of huge explosions. 

The island has added roughly 57,000 square metres of new land, thanks to huge amounts of lava and ash pouring from the active stratovolcano. 

Satellite images taken 19 years apart reveal a massive crater created by the volcano that has taken out about a third of the island's landmass.

The volcano is located about 850 miles southwest of Anchorage, a remote location making observation difficult.

On December 23, observers on a Coast Guard vessel reported spotting ash, lightning, and ejection of incandescent lava.

There have been more than 10 eruptions since mid-December, observatory geophysicist Dave Schneider said.

Prior to that, the last reported eruption was in 1992, when an eruption lasting 19 days sent a cloud rising to 3 km above Bogoslof Island, which was identified on satellite imagery.

Chris Waythomas, a geologist at the Alaska Volcano Observatory, noted how the landscape has changed in a pair of satellite photos taken nearly 19 years apart.

Ash has built up, causing more mass at the northern tip of the island, while the underwater volcano has also created a huge crater that has taken out a third of the island's landmass.  

The island is home to a large population of fur seals, who may have been impacted by the relentless eruptions.

Explosion at Bogoslof Volcano prompts ninth aviation warning (Jan 18) during weeks-long eruption

http://www.ktuu.com/content/news/Explosion-at-Bogoslof-Volcano-prom... 

FAIRBANKS, Alaska (KTUU) - The Alaska Volcano Observatory says it has recorded about 20 explosive events at Bogoslof Volcano since it began erupting about a month ago.

Bogoslof’s most recent explosion occurred at around 1:20 p.m. on Wednesday, and sent up an ash cloud about 31,000 feet high, prompting the ninth red aviation warning AVO has issued for the volcano since mid-December.

AVO Geophysicist Dave Schneider says Wednesday’s eruption was preceded by a series of smaller events earlier in the week.

“It’s safe to say the explosive activity has been variable,” Schneider said. “This was one of the larger events over the past few weeks.”

The ash cloud is not the highest that the volcano has produced during this eruption, with some previous ash clouds reaching as high as 35,000 feet, according to Schneider. But those differences could be more due to atmospheric conditions than the explosion itself.

While the ash cloud does pose a threat to nearby boats and air traffic, wind forecasts show that the fallout is unlikely to be carried towards Dutch Harbor and Unalaska.

Jalisco bathed in ash after powerful eruption of Colima Volcano in Mexico – State of alert

The municipality of Jalisco is ‘bathed’ in ash after the strong explosion of Colima Volcano on January 18, 2017.

 Zapotlán El Grande has experienced a copious rain of crater residues. Civil Protection, police forces and local

firemenurge the community to take precautions. Heavy ashfall has been reported in Zapotlán El Grande, Jalisco after the

latest eruption of the Colima volcano at 00:27am today.Local authorities urged people to take their precautions (masks,

close window, glasses, cover water bodies so they do not contaminate, stay inside the house and sweep the ash) and to

remain vigilant to official information issued by Civil Protection concerning the activity of the volcanic peak.

Zapotlán el Grande is a small municipality, with little more than five hundred square kilometers of surface, located to the

south of Jalisco.

Normally enjoying a pleasant climate, the city is now grey, covered by centimeters of volcanic ashes!

Spectacular Eruptions at Mexico's Colima Volcano (Jan 19)

Powerful explosions at Colima volcano continue unabated.

Dramatic videos show Colima spewing incandescent bombs all over the summit cone and pyroclastic flows with eruption lightning.

An explosion on January 19 was accompanied by a large plume of ash and smoke that rose some 2,000 metres above the crater, and could be heard 50 miles away.

Following this powerful eruption, another, even stronger explosion - one of the most energetic in recent years - occurred in the evening of the same day at 22:16.

It started with a violent cannon-shot like explosion that propelled incandescent bombs to heights well over 2000 meters and covered the whole cone and its lower flanks with impacts, igniting bush fires. Pyroclastic flows from collapsing material also descended the flanks and an ash plume rose to several kilometers height.

On January 15, powerful vulcanian explosions occurred every several hours, generating dense ash columns that rose 2-4 km, covering the upper slopes of the volcano with bombs. Some of them also generated pyroclastic flows that descended the steep upper flank.

Massive Explosion at Mexico's Colima Volcano (Feb 3)

Mexico's Colima volcano erupted with a massive column of ash and smoke rising nearly 2.5 miles above its crater.

The explosion could be seen from miles away and sent ash raining down on surrounding areas in the states of Colima and Jalisco.

The volcano has steadily increased in activity since October 2015, generating towering eruptive columns often accompanied by incandescent bombs and pyroclastic flows.

Since Jan. 3, the magnitude of the explosions has been increasing.

The ongoing volcanic ash fallout has caused significant crop damage in Colima and Jalisco.

"The ash affects blackberry, blueberry, coffee crops, and the avocado that some farmers have in the municipality of Cuauhtémoc," said Jesus Plascencia, Director of Agriculture and Forestry Promotion of Colima.

Thirty eight producers in the municipality of Cuauhtémoc, which is nearly 17 kilometers from the city of Colima, have been affected.

"The amount of ash and the damage it causes to our crops depends on the size of the explosion. The ash reacts with the wind and it burns the fruit," said Luis Enrique Guardado, a producer of blackberry.

After a rain of volcanic ash, blackberry crops are washed with soap and water using pump sprayers.

According to estimates, producers need 3000 liters of water per hectare to clean their crops from the ash.

"The ash is stuck and it is very difficult to remove. We try to remove it well because the fruit looks bad and because it affects photosynthesis and the plant has less production," said Luis Enrique Guardado.

Usually the ripe fruit does not withstand washing and is lost.

"The fruit that can't be completely clean is no longer marketed and producers lose it," said Jesus Plascencia, director of Agriculture and Forestry of Colima.
