    Anthony Watts / 9 hours ago October 2, 2014 From the National Post Is it volcano season? From Japan to Iceland, scientists probe the reasons why there are so many eruptions latelyEruptions caused by climate changeIn recent decades, it has become apparent that the consequences of planetary ice loss might not end with rising sea levels. Evidence has been building that in the past, periods of severe loss of glaciers were followed by a significant spike in volcanic activity.Around 19,000 years ago, glaciation was at a peak. Much of Europe and North America was under ice. Then the climate...

    Deep down in the earth, there is magma, but the magma is not what’s moving, Shelly said. The earthquakes are usually triggered when water and carbon dioxide above the magma move up into higher layers of the earth’s crust and into the cracks of the small faults. The increase in fluid pressure sets off the movements.

    By Michael Snyder, on September 16th, 2014Volcanic Eruption The number of volcanoes that are erupting continues to rise, and scientists cannot seem to explain why this is happening. In 2013, we witnessed the most volcanic eruptions worldwide that we have ever seen in a single year, and this increased activity has carried over into 2014. In recent months, we have seen major volcanoes roar to life in Russia, Peru, Hawaii, Reunion Island, Indonesia, and all over Alaska. It is highly unusual for so many volcanoes to all be erupting at the same time. According to Volcano Discovery, a whopping 34...

    Mauna Loa, the world's largest active volcano, has rumbled back to life in Hawaii over the past 13 months with more seismic activity than at any time since its last eruption, scientists say, while calling it too soon to predict another blast. The volcano, which last erupted in 1975 and 1984, has been rattled since March 2013 by earthquakes of the same type and in the same location as the temblors that preceded those explosions, said Wes Thelen, a seismologist for the US Geological Survey's Hawaiian Volcano Observatory.

Dense ash plumes rising from the summit crater can be seen on this morning's satellite images, and a MODIS hot spot is visible on the latest satellite data, suggesting fresh magma continues to arrive at the volcano's summit crater. In the meanwhile, the ash and SO2 plume has drifted and spread over more than 3000 km to the E and SE, covering a vast area that includes parts of northern and eastern Australia.

It is now recognized to be a single volcano - instead of a volcano complex with multiple vents. Tamu Massif has a footprint that covers more area than any other volcano - about 120,000 square miles (310,800 square kilometers) - an area about the size of New Mexico. It also has a larger mass than any other known single volcano on Earth. How could this enormous volcano have...

    Antarctica is a land of ice. But dive below the West Antarctic Ice Sheet, and you'll find fire as well, in the form of subglacial volcanoes. Now, a new study finds that these subglacial volcanoes and other geothermal "hotspots" are contributing to the melting of Thwaites Glacier, a major river of ice that flows into Antarctica's Pine Island Bay. Areas of the glacier that sit near geologic features thought to be volcanic are melting faster than regions farther away from hotspots, said Dustin Schroeder, the study's lead author and a geophysicist at the University of Texas at Austin. This melting...

    Some worrying developments are taking place at the Super Volcano located beneath Yellowstone National Park; the kind of developments that were seen shortly before other volcanoes erupted. Not only was there a sudden rise in the elevation of the ground, and development of new cracks, but a gas called Helium-4, a very rare type of Helium, has begun coming out of the surface. It is the presence of this gas that has scientists quite concerned. If the Yellowstone Super Volcano were to erupt, it would be 2,000 times bigger than the eruption of Mount St. Helens in the 1980′s.

  • The Ashfall Story

    05/10/2010 4:23:15 PM PDT · by SunkenCiv · 35 replies · 760+ views
    About 12 million years ago, a volcano in southwest Idaho spread a blanket of ash over a very large area. One or two feet of this powdered glass covered the flat savannah-like grasslands of northeastern Nebraska. Most of the animals which lived here survived the actual ashfall, but as they continued to graze on the ash covered grasses, their lungs began to fill up with the abrasive powder. Soon their lungs became severely damaged and they began to die. The smaller animals died first (smaller lung capacities) and finally, after perhaps three to five weeks, the last of the rhinos...

    Eyjafjallajökull began erupting on March 20, but few people other than volcanologists and Icelanders took notice at first. For weeks, all it did was spurt lava gently out of an exposed ridge. On April 14, though, the eruption suddenly shifted a few kilometers west -- no longer on open land, but beneath an ice cap. Just as happened at Sveifluháls, magma met ice and turned it to steam, throwing ash into the stratosphere. European airline flights shut down for days over worries about how the ash might affect jet engines. What a difference a little ice makes. Had the second...

The mainstream explanation was that the development in Asia (China and India, essentially) – where the industrial sulfur dioxide emissions increased 60 percent from 2000 to 2010, mainly driven by coal burning – was behind the cooling of Earth. According to the study by Ryan Neely which helped cement the mainstream view, small amounts of sulfur dioxide emissions from Earth's surface...

Now they have been astonished by a more explosive explanation – a cataclysmic volcano that had erupted a century earlier, thousands of miles away in the tropics, and wrought havoc on medieval Britons. Scientific evidence – including radiocarbon dating of the bones and geological data from across the globe – shows for the first time that mass fatalities in the 13th century were caused by one...

    Should anyone ever decide to make a show called "CSI: Geology," a group of scientists studying a mysterious and rapidly inflating South American volcano have got the perfect storyline. Several universities are essentially working as geological detectives, using a suite of tools to piece together the restive peak's past in order to understand what it is doing now, and better diagnose what may lie ahead. It's a mystery they've yet to solve. Uturuncu is a nearly 20,000-foot-high (6,000 meters) volcano in southwest Bolivia. Scientists recently discovered the volcano is inflating with astonishing speed. "I call this 'volcano forensics,' because we're...

    A string of a dozen volcanoes, at least several of them active, has been found beneath the frigid seas near Antarctica, the first such discovery in that region. Some of the peaks tower nearly 10,000 feet (3,000 meters) above the ocean floor — nearly tall enough to break the water's surface. "That's a big volcano. That's a very big volcano. If that was on land it would be quite remarkable," said Philip Leat, a vulcanologist with the British Antarctic Survey who led a seafloor mapping expedition to the region in 2007 and 2010. The group of 12 underwater mountains lies...

    Explosive volcanic eruptions might be attention grabbing, but a new review of research finds that their environmental impact pales in comparison to human activities. According to the research, humans put out the same amount of carbon dioxide in three to five days that all of the volcanoes on Earth put out in one year. "Anthropogenic carbon dioxide emissions dwarf global volcanic carbon dioxide emissions," study researcher Terrance Gerlach, of the U.S. Geological Survey, said in a statement. Carbon dioxide, or CO2, is the main greenhouse gas responsible for climate change. Gerlach crunched the carbon dioxide numbers from earlier studies of...

    Tens of thousands of passengers in Australia and New Zealand were stranded when airlines suspended flights Sunday as an ash cloud from an erupting volcano in southern Chile spread, threatening to damage engines. Australia's national carrier, Qantas Airways, said all the airline's flights in and out of the southeastern city of Melbourne would be grounded. Other carriers including Virgin Australia and discount airlines Jetstar and Tiger similarly suspended flights. Up to 30,000 passengers in New Zealand and Australia found themselves stuck, according to airlines' estimates. Sunday afternoon, frustrated travelers lined up in airports and looked for last-minute accommodation. Hotels near...

    As good a read as it is throughout, Lawrence Joseph's book, Apocalypse 2012: An Investigation into Civilization's End devotes a spine-tingling chapter to two ticking bombs in our own backyard — Yellowstone National Park and California's Long Valley Caldera. Both locations are home to massive supervolcanoes. Geologists say these submerged magma chambers fill up over the course of several hundred thousand years, then shoot their wads skyward in climate-changing events. And both are due for their periodic eruption. The last supervolcano to erupt on the planet was Mount Toba in Sumatra — 74,000 years ago. Incredibly, both Yellowstone and Long...

    Update: It's possible that a meltdown may already have occurred at one nuclear power plant. As AP wrote 4 minutes ago: An official with Japan's nuclear safety commission says that a meltdown at nuclear power plant affected by the country's massive earthquake is possible. Ryohei Shiomi said Saturday that officials were checking whether a meltdown had taken place at the Fukushima Dai-ichi power plant, which had lost cooling ability in the aftermath of Friday's powerful earthquake. Reuters reports: Japanese nuclear authorities said that there was a high possibility that nuclear fuel rods at a reactor at Tokyo Electric Power's Daiichi...

    Scientists in Iceland are warning that another volcano looks set to erupt and threatening to spew-out a pall of dust that would dwarf last year's event.... Geologists detected the high risk of a new eruption after evaluating an increased swarm of earthquakes around the island's second largest volcano. Pall Einarsson, a professor of geophysics at the University of Iceland, says the area around Bárdarbunga is showing signs of increased activity, which provides "good reason to worry". He told the country's national TV station that a low number of seismometer measuring devices in the area is making it more difficult to...

    Iceland's Eyjafjallajokull wreaked havoc on European air travel, but it could have been worse. Much, much, much worse The eruption of Iceland's Eyjafjallajokull caused billions of dollars in economic damage, and left millions of travelers stranded. But on the Volcanic Explosivity Index — volcanologists’ tool for rating the severity of an eruption — the event rated only a two out of a possible eight. More severe eruptions cause “death and destruction” on a planetary basis, points out Simon Winchester in The Guardian. “They can darken skies and cause devastating changes in the weather. They can and do bring about the...
