    Airplanes are being warned to avoid airspace near an erupting Alaska volcano as it spews ash 30,000 feet above sea level. The National Weather Service said Saturday ash is being blown to the west and northwest of Pavlof Volcano. Pavlof began erupting three days ago, pushing lava out from a vent near its summit. On Friday, the ash cloud reached 16,000 feet. Alaska Volcano Observatory Geophysicist Dave Schneider says the eruption intensified at 6 a.m. Saturday, sending the ash cloud higher.

    Alaska's Mount Churchill volcano erupted some 1,200 years ago, spreading ash from Canada to Germany... Mount Churchill is also an impressive volcano, the tallest on land in the United States and one of the towering, snowy peaks of Alaska's Wrangell-St. Elias Mountains. But Churchill's blast in A.D. 843 ejected just 12 cubic miles (50 cubic km) of ash, a layer now called the White River Ash, according to the new study, published in the September 2014 issue of the journal Geology... If moderate volcanic eruptions can spread ash for thousands of miles, then these blowouts may be more hazardous than...

    Ajai RajSeptember 8, 2014 Last Friday's eruption at Iceland's Bardarbunga volcano had many worried about the possible impacts of a larger eruption on air travel. Another eruption at Hawaii's Kilauea volcano has caused a state of emergency to be declared on Big Island, as lava flows from the ongoing eruption have advanced within a mile of a residential zone. That's just one example of how much danger volcanoes pose to the U.S. — and we aren't doing much about it. Compared with Iceland, the U.S. is much more vulnerable to volcanic disasters — and has been failing at monitoring these...

    Mount Rainier, one of the most dangerous volcanoes in the U.S. and in the world, is widely expected to erupt again. The only unknown facing scientists is when the massive stratovolcano, 4,392 meters tall and located 87 kilometers southeast of Seattle in Washington state, will finally explode. Scientists from the United States and Norway recently mapped the electric and magnetic signatures of magma flows beneath Mount Rainier (pronounced “ray-near”). They’ve also discovered a mammoth magma reservoir below the mountain that will fuel any eruption with massive magma flows. The research found out that magma or fluid molten rock is trapped...

    'Catastrophic' event at Campi Flegrei 39,000 years ago Volcanic eruption near Naples may have killed Neanderthals Some researchers are suggesting that Neanderthals were driven to extinction by a massive volcanic eruption near Naples. The suggestion is one of the topics under debate this week at a conference at London's British Museum examining what forces led to the destruction of the Neanderthals and what led to the triumph of the homo sapiens. One new theory holds that a gigantic eruption of the volcano in the Campi Flegrei area near Naples 39,000 years ago was catastrophic for the Neanderthals. That was the...

    The Neanderthals were a hardy species that lived through multiple ice ages and would have been familiar with volcanoes and other natural calamities. But the eruptions 40,000 years ago were unlike anything Neanderthals had faced before, Cleghorn and company say. For one thing, all the volcanoes apparently erupted around the same time. And one of those blasts, the Campanian Ignimbrite, is thought to have been the most powerful eruption in Europe in the last 200,000 years... The researchers acknowledge that there are gaps in the volcanoes theory. For instance, the time line needs to be better defined -- did...

    During the Late Bronze Age, the Aegean volcanic island of Thera erupted violently, spreading pumice and ash across the eastern Mediterranean and triggering frosts as far away as what is now California. The Theran town of Akrotiri was completely buried. Tsunamis up to 12 meters high crashed onto the shores of Crete, 110 kilometers to the south, and the cataclysm may ultimately have sped the demise of Crete's famed Minoan civilization. For nearly 30 years, archaeologists have fought over when the eruption took place. Those who rely on dates from pottery styles and Egyptian inscriptions put the event at roughly...

    According to a recent international study, the volcano of the island Santorini, Greece, erupted in the 16th century BC and not earlier. The survey characterized a number of research studies that took place in the past and have indicated that Santorini's volcano may have erupted a century earlier, as unreliable because the method based on tree-ring measurements that they used, could not provide them with accurate results. An international team of researchers led by Paolo Cherubini from the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) has demonstrated in the scientific journal Antiquity, that this method cannot provide...

    Geological testing was done at the site in 2005, for the purpose of placing pillars in solid ground so that the stability of the roof would not be an issue in the event of an earthquake. What they found while using high resolution travel time tomography, a method of getting images from under the surface of the earth using waves of energy, were underground cavities. These were both man made and natural. The man made gaps in the earth were filled with rocks, ceramics, and other items of interest to archeologists.

    Although ancient ruins in Akrotiri were discovered in 1860 by workers quarrying volcanic rock for the Suez Canal, large scale excavations there didn't begin until 1967. An archeologist by the name of Spyridon Marinatos suspected there were extensive ruins beneath the farmlands at Akrotiri and wrote about his theory in 1936. Due to the outbreak of World War II and the Greek Civil War, he had to postpone his explorations. Earlier digs in the area had been destroyed by plowing of the fields and there were no written records of where they had taken place or what the findings were....

    While approximately forty buildings have been uncovered at Akrotiri, there are six that have been given more attention than the others. The architecture and function of each building is different. The largest building uncovered so far, Xeste 4, is three stories high and believed to be a public building because of its dimensions. The staircase had fragments of frescoes on either side depicting males ascending in a procession. The second largest building, Xeste 3, was at least two stories high, with fourteen rooms on each floor. The rooms were decorated with paintings and some had more than one door. One...

NASA's Messenger spacecraft in orbit around Mercury and the Stereo-A, which studies the sun from Earth orbit, suffered no damage from the passing solar storms. On April 20, the sun fired off a solar eruption that sent huge wave of plasma and charged particles, called a coronal mass ejection (CME), toward Mercury. The next day, the sun unleashed two more CMEs in the same direction, and managers from both the Messenger and Stereo missions were alerted of the potential...

    May 16, 2010 Scientists forecast decades of ash clouds Many more of Iceland’s volcanoes seem to be stirring Iceland could be at the start of a surge in volcanic activity that may produce more eruptions Jonathan Leake and Chris Hastings THE Icelandic eruption that has caused misery for air travellers could be part of a surge in volcanic activity that will affect the whole of Europe for decades, scientists have warned. They have reconstructed a timeline of 205 eruptions in Iceland, spanning the past 1,100 years, and found that they occur in regular cycles — with the relatively quiet phase...

    Get Ready for Decades of Icelandic Fireworks Get Ready for Decades of Icelandic Fireworks We're not quite back to the pre-plane era, but air travel over and around the north Atlantic might get a lot more disrupted in the coming years. Volcanologists say the fireworks exploding from the Eyjafjallajökull volcano on Iceland, which is responsible for the ash cloud that is grounding all commercial flights across northern Europe, may become a familiar sight. Increased rumblings under Iceland over the past decade suggest that the area is entering a more active phase, with more eruptions and the potential for some very...

    Air traffic in Sweden and Europe is currently paralyzed due to a volcanic eruption in Iceland. How could a local event in the furthest reaches of Northern Europe paralyze an entire continent? The reason is that the ash that fills the air following a volcanic eruption has a much denser content than a normal dust or ash cloud. The ash affects air-traffic safety in a number of ways. The ash comprises minerals, which are extremely small and hard rock particles. They are so hard that they can have a blasting effect on the aircraft’s cockpit windowpanes when an aircraft meets...

    REYKJAVIK (Reuters) – A volcanic eruption in Iceland, which has thrown up a 6-km (3.7 mile) high plume of ash and disrupted air traffic across northern Europe, has grown more intense, an expert said on Thursday. The eruption under the Eyjafjallajokull glacier continued to spew large amounts of ash and smoke into the air and showed no signs of abating after 40 hours of activity, said Pall Einarsson, a geophysicist at the University of Iceland. "The seismographs are showing that since this morning the intensity of the eruption seems to be growing," he said. Hot fumes had melted up to...

    NASA's STEREO-B spacecraft is tracking four active regions strung across the eastern hemisphere of the sun. Click on the image below to set the scene in motion--and keep an eye on number 4. The movie shows an eruption of unstable magnetic loops. The blast occured around 0130 UT on February 5th and it appears to have hurled some material in the general direction of Earth. Images from the Solar and Heliospheric Observatory (SOHO) are not yet available to evaluate that possibility. Stay tuned for updates in a few hours.

    December 18, 2009 Deep-sea volcano erupts 4,000ft under the Pacific Sophie Tedmanson in Sydney Scientists have filmed a volcanic eruption 4,000ft (1,220m) under the sea causing molten lava to flow across the deep ocean floor. The incredible footage, recorded by a submersible robot, shows the exact moment that a deep-sea volcano erupts from the ocean floor, sending an explosion of bright red lava bubbles and plumes of smoke-like sulphur through the water. The eruption of the West Mata volcano was filmed by US scientists in May during an underwater expedition south of Samoa. It is the deepest erupting volcano to...
  • Supervolcano eruption -- in Sumatra -- deforested India 73,000 years ago

    CHAMPAIGN, Ill. — A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report. The volcano ejected an estimated 800 cubic kilometers of ash into the atmosphere, leaving a crater (now the world's largest volcanic lake) that is 100 kilometers long and 35 kilometers wide. Ash from the event has been found in India, the Indian Ocean, the Bay of Bengal and the South China Sea. The bright ash reflected sunlight off the landscape, and volcanic sulfur...

    A vast pool of molten rock in the continental crust that underlies southwestern Washington state could supply magma to three active volcanoes in the Cascade Mountains -- Mount St. Helens , Mount Rainier and Mount Adams... Other scientists dismiss the existence... Rather than magma heated to 1,300 to 1,400 degrees, some think it could be water...

    The site was found by accident when the Suez Canal was being constructed in 1860. Workers quarrying Santorini's volcanic ash discovered the ruins, but serious excavations at the site didn't begin until 1967. An unfortunate collapse of the roof in 2005, which killed a British tourist, caused the site to be closed. It's scheduled to be reopened sometime after 2010. Greek bureaucracy has brought the repairs of the building to a halt, which has caused Santorini's tourist trade to suffer. Akrotiri is referred to by some as the "Minoan Pompeii" because of the similarities of the destruction by volcano and...

    NASA's Earth Observatory inspires a couple of different views this week. First of all, there's this: Fogo, Cape Verde Islandswhich in part notes that there are villages inside the caldera which holds the volcanic peak of Fogo (actually Pico do Fogo, if you're wondering why it's labeled Pico in the picture). I wouldn't think that's exactly prime real estate! In the picture below you can see the villages as small white dots, and the road to them through the caldera. The other images are a few I found that the two villages from various perspectives. View from the 1995 eruption...
