Azores: Experts Concerned With Abnormal Seismic Activity
“Experts in the Azores have alerted the population of São Miguel Island for seismic activity which they considered to be above normal. The seismic events where located in the system of Fogo and Congro lakes, the central region of the island.
‘The situation is ongoing and the number of microseisms is slightly above reference values’ said Wednesday João Luís Gaspar from the Center of Volcanology and Geological Risk Assessment (CVARG) of the University of the Azores.
He also said that the seismic activity was the result of ‘very low magnitude earthquakes’ adding that ‘none of which have been felt by the population.’
Declining to comment on what the evolution of the crisis could be João Luís Gaspar recalled that ‘seismological activity is difficult to predict,’ but that the possibility could not be eliminated of an earthquake occurrence which may be felt by the population. He said, ‘It does not mean it will happen; only that one cannot eliminate that possibility.’
According to the CVARG website, the Fogo-Congro system is one of the most critical seismologic areas of the archipelago where accumulated tensions exist resulting from the lithospheric interplay of the Eurasian, African and American plates.” Read more.
Texas: ‘Red Tide’ Kills Thousands of Fish, Litters Shoreline ‘As Far as the Eye Can See’ from Port Aransas to Mansfield Channel
CORPUS CHRISTI (Kiii News) – “The red tide is growing stronger out on Padre Island and it’s wreaking havoc on wildlife. Thousands of dead fish, as far as the eye can see, now litter the waterline from Port Aransas to Mansfield Channel.
‘We’ve seen flounder, yellow tail, mullet, lady fish and a few sea robins,’ says fisherman Daniel McLain.
It’s a natural occurrence, typically happening each fall. This year, the problematic algae bloom is particularly strong and this weeks rain storms may have made the problem worse.
‘It’s kind of heartbreaking to see it like this, I guess it’s Mother Nature’s course,’ said McLain.
‘We are sampling for the algae itself, but also the dead fish to figure out how much amount of toxins it took to kill them,’ says Dr. Paul Zimba, the Director at the Center for Coastal Studies.
Researchers from Texas A&M Corpus Christi were out studying the natural phenomenon. They have a warning for people who like to walk their dogs on the beach, to not let them eat the dead fish. The toxic fish could actually end up killing your pet.” Source.
Red Tide at Mustang Island, TX
Russia’s Mount Shiveluch Erupting, Smoke and Ash Reach 10,000 Meters (6+ Miles), No-Fly Warnings Issued for Surrounding Area
“Reports speak of a violent volcanic eruption of Mount Shiveluch on Russia’s Far Eastern Kamchatka Peninsula.
Smoke and ash from the volcano have climbed to 10 kilometres, sparking no-fly warnings for the surrounding area. Snow around the crater is rapidly melting, creating mudslides.
Shiveluch supports a caldera of 1.5 kilometres in diameter. Its current activity period started in 1980.” Source.
Activity is ongoing – “An explosive eruption is taking place at Russia’s Shiveluch volcano (sometimes called Sheveluch or Sopka Shiveluch), located in the far eastern Kamchatka Peninsula, prompting no fly zones to be imposed in the region. Ash plumes have risen to 34,500 ft (10.5 km) while seismic activity is ongoing. The official Itar-Tass news agency reported on Monday that the highest-level warning has been issued for aviation.” Read more.
Canary Islands: Red Alert at El Hierro Volcano As Eruption Bubbles Rise From the Sea
“Villagers are mentioning ‘bubbles’ coming up in the spotted area in the sea. We expect to receive fastly images from the bubbles as the many camera teams with their superior equipment will certainly be able to shoot detailed video from an event which can be seen by the naked eye.
Ramon Ortiz, a technician from the CSIC (Centro Superior de Investigaciones Científicas) is predicting that a new island is being formed at this moment and that the chance that it will happen now is evaluated as very probable, at least of the eruption process will continue a little longer.” Read more.
Spewing volcano forces Spain to close island port – “(AP) MADRID — Spanish authorities say activity by an underwater volcano has led them to close access to a port on El Hierro island. Ships have been ordered away from waters around La Restinga and aircraft have been banned from flying over the island’s southern tip. The port’s 600 residents were evacuated Tuesday after volcanic activity began. The regional government of the Canary Islands says scientists have detected airborne volcanic fragments called pyroclasts rising from the sea off La Restinga.” Read more.
‘Katla’ Rumbles Iceland: Experts Warn of Imminent Eruption Even More Powerful Than The ‘Small’ One That Paralyzed Air Traffic Last Year
“Experts are warning that an eruption could be imminent at an even more powerful Icelandic volcano than the one that paralysed air traffic last year.
Seismologists are nervously watching rumblings beneath Katla which could spew an ash cloud dwarfing the 2010 eruption that cost airlines two billion dollars (£1.27 billion) and drove home how vulnerable modern society is to the whims of nature.
Brooding over rugged moss-covered hills on Iceland’s southern edge, Katla is a much bigger beast than the nearby Eyjafjallajokul volcano, which blasted ash all over Europe for several weeks in an eruption that local scientist Pall Einarsson describes nonetheless as ‘small’.
Named after an evil troll, Katla has a larger magma chamber than Eyjafjallajokul’s.
Its last major eruption in 1918 continued more than a month, turning day into night, starving crops of sunlight and killing off some livestock.
The eruption melted some of the ice-sheet covering Katla, flooding surrounding farmlands with a torrent of water that some accounts have said measured as wide as the Amazon.
Now, clusters of small earthquakes are being detected around Katla, which means an eruption could be imminent, seismologists say. The earthquakes have been growing in strength, too.
After a long period of magnitude three tremors, a magnitude four quake was detected last week.
‘It is definitely showing signs of restlessness,’ said Mr Einarsson, a professor of geophysics at the University of Iceland.
Teams of seismologists and geologists at the university are tracking the spike in seismic activity and working with disaster officials to prepare communities near Katla like Vik, a small town of some 300 people that is flanked by black sand beaches.
Civil defence authorities have been holding regular meetings with scientists. Disaster officials have also drafted an evacuation plan and set aside temporary housing, but many fear they may have less than an hour to evacuate once the volcano erupts.
Iceland sits on a large volcanic hot spot in the Atlantic’s mid-oceanic ridge. Eruptions, common throughout Iceland’s history, are often triggered by seismic activity when the Earth’s plates move and magma from deep underground pushes its way to the surface.
The longer pressure builds up, the more catastrophic an eruption can be. Records show that Katla usually has a large eruption twice a century. Since its last eruption was almost exactly 93 years ago, it is long overdue for another, seismologists say.” Read more.
Canary Islands: Underwater Volcanic Eruptions Edge Closer To El Hierro Mainland
By Mark Dunphy – “Two new underwater volcanic eruptions have occurred off the south coast of El Hierro, the smallest and southernmost island in the Canary Islands.
Seismologists say two separate fissures have been identified less than 3.7 kilometres and 2.8 kilometres from La Restinga, a town on the southeast of the island.
Authorities have detected a sulphur odour in the area while dead fish have also been spotted floating on the surface of Las Calmas Sea.
The fresh eruptions occurred 48 hours after a subsea eruption, Spain’s first since an eruption on La Palma in 1971, occurred approximately 5 kilometres from La Restinga. The town’s 570 residents were subsequently evacuated as a precautionary measure in the event of volcanic activity moving closer to the island.
The eruptions take place amidst an unprecedented earthquake swarm in El Hierro. The number of earthquakes recorded since July 17, 2011 on El Hierro has now exceeded 10,300.
Hierro, a shield volcano, has had a single historic eruption from the Volcan de Lomo Negro vent in 1793. The eruption lasted approximately one month and produced lava flows.
The recent surge in the number and intensity of earthquakes prompted officials from Spain’s Instituto Geográfico Nacional (IGN) and The Canary Islands Government to raise the alert level for the Hierro volcano to ‘Yellow’ late last month. The alert remained in place on Thursday, but the estimated 11,000 residents of El Hierro were being reassured not to be alarmed.
The majority of the earthquake activity shifted from El Golfo in the island’s northwest to beneath the Las Calmas Sea in the south earlier this month. Surface deformations exceeding 35mm have also been recorded on the island in recent weeks.
A Red Alert was issued by local authorities for the town of La Restinga, where local residents were evacuated from on Tuesday evening. Spanish Prime Minister José Luis Rodríguez Zapatero and cabinet colleagues later attended an emergency briefing on the developing situation.” Read more.
Chile: Volcanic Activity Continues At Puyehue Corón-Caulle
By Mark Dunphy – “NASA satellite imagery shows that the eruption of Puyehue Corón-Caulle Volcano is continuing after more than 4 months of activity.
A conspicuous plume of volcanic gases and fine ash rose above the volcano on Sunday (October 9, 2011), and blew southeast over Argentina.
In the top natural-color satellite image the mountainous landscape is covered with gray ash, largely snow-free for the first time in several months. To the north and southwest of the active vent is a lava flow, its textured appearance suggestive of thick lava. Immediately west of the vent the flow appears fresh—its dark surface not yet covered by lighter ash.
In a false-color image made from shortwave infrared, near infrared, and visible light data (above, lower), the vent and nearby lava flow are bright orange. This is a sign of intense heat, and likely indicates ongoing emissions of lava. These images were acquired by the Advanced Land Imager (ALI) aboard the Earth Observing-1 (EO-1) satellite.” Source.
Japan: Shinmoedake Volcano in Kyushu May Become Active Again Soon
“Mount Shinmoedake in the central part of the volcanic Kirishima mountain range in southern Kyushu could resume its volcanic activities within several months as magma continues to be piled up deep underground, the Coordinating Committee for Prediction of Volcanic Eruptions said on Oct. 11.
Within about four months, the amount of accumulated magma is likely to increase close to levels registered in late January when the volcano became active, the committee said.
According to the group, GPS monitoring found that the 1,421-meter volcanic mountain has been swelling steadily — an indicator of the increasing size of accumulated magma. If the amount of accumulated magma reaches levels registered in late January, Mount Shinmoedake, which straddles Miyazaki and Kagoshima prefectures, could resume its volcanic activities on a scale comparable to that for late January, the committee said. Mount Shinmoedake has erupted seven times since mid-June after remaining quiet for about two months since mid-April.
Committee chairman Toshitsugu Fujii said, ‘There could be various scenarios. It is hard to think the volcanic activities will stop quickly.’ He said the mountain could erupt on a scale larger than that for late January, and other craters in the Kirishima mountain range could also erupt.” Read more.
Canary Islands: Subsea Volcanic Eruption Underway Near El Hierro
By MARK DUNPHY – “A submarine volcanic eruption is taking place approximately 5 kilometres off the southern coast of El Hierro, the smallest of The Canary Islands.
The Mayor of La Frontera (El Hierro), David Cabrera, confirmed in an interview on Radio iron Garoé that ‘underwater eruption’ is taking place about 900 metres beneath the sea surface five kilometres south of La Restinga. The eruption has been ongoing for four hours, the Mayor said.
Spanish newspaper laopionion.es quoted the Minister of emergencies of the Cabildo of El Hierro, Maria of Carmen Morales, as saying the eruption is taking place because ‘the seismic movement of 4.3 occurred on Saturday afternoon caused a fissure, from where the energy is been released’. Scientists remain unclear if the emissions are gas or lava.
A meeting of PEVOLCA – Actualidad Volcánica de Canarias, comprising representatives of Instituto Geografico Nacional (IGN) and The Canary Islands Government, took place on the Spanish Island. In a statement issued shortly before 4 p.m. local time, the IGN stated (translated from spanish language press release): ‘…although there is no certainty that at the moment is producing an underwater volcanic eruption, since the last morning there has been a release of fluids and volcanic gas on the southern coast of the island.’
‘Scientists from IGN have reported to the direction of the Plan all the indicators that have been analyzed to point towards the possibility of the beginning of an eruptive process that has changed the type of waves that have registered seismographs in the last hours, implying the beginning of emission of gases or lava…'” Read more.
Canary Islands: Something is Happening at El Hierro as Magma Churns Below Surface and Earthquake Swarms Increase
“CANARY ISLANDS – An intensified sustained earthquake swarm is now taking place at the Canary Islands and it appears the magma is now on the move again bubbling closer to the surface and incinerating more rock in the process. Over the last 24 hours, we’ve seen the depths of the tremors rising up to within 11 km from a depth average of about 14.5 to 15 km. The number of seismic volcanic tremors has also doubled at El Hierro since Wednesday. On Wednesday, October 5, there were 79 recorded seismic events. On Thursday, there were 160 and on Friday, October 7th, there were 177.” Source.
Indonesia: Tourists, Fishermen Told to Stay Clear of ‘Child of Krakatoa’ as Tremors Soar From 200 a Day to 7,200
“JAKARTA, Indonesia — Authorities are warning tourists and fishermen to stay more than a mile (two kilometers) from a smoking Indonesian volcano known as ‘Child of Krakatoa.’
The volcano in the Sunda Strait, 80 miles (130 kilometers) west of the capital, Jakarta, was created by the same tectonic forces that led to the 1883 Krakatoa eruption that killed tens of thousands of people.
Its ‘child,’ growing five yards (meters) a year, is now 1,320 feet (400 meters) tall and popular among hikers.
Gede Suantika of the Center for Volcanology says the mountain’s alert level was raised to the second-highest level last week after the number of volcanic tremors soared from 200 a day to 7,200.
Suantika said Tuesday that he worries a powerful burst could shoot incandescent rocks down its slopes and far into the ocean.” Read more.
Argentina: 500,000 Sheep Dead in Patagonia Because of Volcanic Ash From Chilean Volcano
“Half a million sheep have already died in Argentine Patagonia as a result of the eruption of the Chilean volcano Puyehe, which has covered most fields in the province of Chubut with a film made of a mix of mineral ash.
The sheep die unable to find food and when they can the volcanic ash mix turns into a toxic grind for the animal.
‘We estimate over half a million sheep have been lost because of the ashes which continue to be spewed by the volcano’ said Ernesto Siguero president of the Chubut Rural Society.
Ashes also weigh on the sheep’s wool making it harder to move around with the extra burden and ‘once they sit it’s hard for them to stand up’. Likewise the continued ash in the air harms livestock’s sight.
But people living in the area are also suffering the consequences of the ashes in their daily lives. The constant ash blocks chimneys, gets into the water pipes, covers with dust light bulbs and when it’s windy, drivers guide themselves by the culverts because of the almost zero visibility.
In some areas the volcanic ash has accumulated almost a metre high making it even difficult for the 4 by 4 to vehicles to move around.” Read more.
