    Volcanoes beneath the Sea A Fiery Birth Last May, amazed scientists watched as lava and ash blasted through the surface of the Pacific Ocean and high into the air. They were getting a rare glimpse of a live eruption from an undersea volcano. How do these submarine volcanoes work? "Fiery birth of a new Pacific island!" read the May 24 announcement from the Australian Commonwealth Scientific and Industrial Organization (CSIRO). CSIRO had sent a team of researchers to study the dormant undersea Kavachi volcano in the Solomon Islands east of Australia. They discovered that the volcano was not dormant at...
  • Overdue Supervolcanoes 'May Erupt Soon'

    SUPERVOLCANOES WARNING Slumbering supervolcanoes powerful enough to wipe out much of the planet may awaken much sooner than it had previously been thought. Experts believed it would take hundreds of thousands of years for reservoirs of molton rock, or magma, beneath a supervolcano to build for an eruption. But a new study indicates the time between super-eruptions can actually be tens of thousands of years - and many are already long overdue. A blast from a supervolcano would be strong enough cause mass extinction and change the world's climate. The findings, published in the Journal of Petrology, are bad...
  • Volcanic Warming Eyed in 'Great Dying'

    WASHINGTON - An ancient version of global warming may have been to blame for the greatest mass extinction in Earth's history. In an event known as the "Great Dying," some 250 million years ago, 90 percent of all marine life and nearly three-quarters of land-based plants and animals went extinct. Scientists have long debated the cause of this calamity — which occurred before the era of dinosaurs — with possibilities including such disasters as meteor impacts. Researchers led by Peter Ward of the University of Washington now think the answer is global warming caused by volcanic activity. Their findings are...

  • One or Two Quakes a Minute at in Wash. (Mt. St. Helens)

    Small earthquakes rattled Mount St. Helens at the rate of one or two a minute Monday, and seismologists were working to determine the significance of some of the most intense seismic activity in nearly 20 years. Carbon dioxide and sulfur gas samples collected above the volcano - which erupted to devastating effect in 1980 - will help scientists figure out what is going on beneath the 925-foot-high dome of hardened lava within the mountain's gaping crater. They want to know whether the quakes are the result of water seeping into the mountain or magma moving under its crater. In either...

    One picture and several links. Note that on the Volcano LiveCams page, you can also see volcano cams around the world. Due to the report about Mt. St. Helens that happened over the weekend, I checked the St. Helens cam; and according to the picture on that page, it's supposed to be up on "Monday, September 28, 2004". Somebody did NOT realize that this was a leap year, apparently. So maybe it will be up by tomorrow in case St. Helens burps. Pic first, then links: Wild spattering from a collapsing Hornito (there are so many thoughts...) Lava flows in...

    Our first feature is the image of the Etna eruption. As of September 10, the eruption is continuing with a new effusive site opening. The lava flows are near the summit and aren't threatening any structures or villages. Click the picture to see it full-size. For more, click the article link at top and choose "Septembre 2004" at left. Our second feature is at the link below; six QTVR panoramas of the just-ended Piton de la Fournaise eruption. Stunning! If you have the bandwidth to handle it, look at the big ones. The aerial view is mind-boggling (though grainy in...

    Scientists exploring the deep sea in the Gulf of Mexico have discovered seeps that resemble a paved road. Seeps are places where oil and other hydrocarbons bubble up from under the seabed. But these seeps, discovered by researchers with Texas A&M University at Corpus Christi, are covered in asphalt. The seeps were found along salt domes that lie about two miles down in the southern Gulf of Mexico. Deep sea cameras revealed about 20 salt domes that had collapsed or broken apart. Along the edges were large patches of asphalt, or hardened tar. Scientists photographed them and took samples;...

    Source: University Of North Carolina At Chapel Hill Date: 2004-04-26 Classic View Wrong, Scientists Say, Huge Pots Of Magma Not Brewing Under Most Volcanoes CHAPEL HILL -- About 75,000 years ago, some scientists say, the last truly colossal volcanic eruption on Earth came close to wiping out all the primates, including humans. That eruption occurred when the Toba volcano in Indonesia exploded in an almost unbelievably shattering display. Other people with a flare for the dramatic warn that a supervolcano underlying Yellowstone National Park could erupt in the not-so-distant future and push humanity to the verge of extinction.

    (CBS) For years, CBS News Correspondent Sandra Hughes reports, scientists have tried to understand the dynamic nature of Yellowstone National Park. "It's beautiful up here, everybody should see this at one time or another," says one appreciative observer. Scientist Lisa Morgan may have unlocked one piece in the puzzle, deep below the park's biggest lake. "It is kind of the last unmapped frontier in Yellowstone National Park," says Morgan. What she found looks more like the surface of the moon. Using sonar she's identified a massive bulging dome the size of seven football fields. The only other underwater dome in...
