    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...

    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...

    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;...

    (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...

    It's bad enough when, every few million years, an asteroid rocks our planet. It's worse if the impact triggers regional or global volcanic activity, which is not only hazardous to nearby plants and animals but can choke Earth's atmosphere with deadly gases for months or years. But there's also a possible bright side, like the birth of nice places like Hawaii. For more than three decades, scientists have explored the question of whether an asteroid impact could cause significant volcanic eruptions, hot spots that spring up out of nowhere and create new landforms or rearrange old ones. The process might...

The eruption column reached a height of =25 km. Most of the ensuing deaths were caused by the many tsunamis that thundered along the coastline from late afternoon August 26th, to midday on the 27th August. The 40 m high tsunamis generated ravaged the shores of the Sunda Straits and caused 36,000 deaths in 295 coastal fishing villages, whilst...

    Findings reported from the first ever detailed exploration of the Gakkel Ridge—the northernmost segment of the worldwide mid-ocean ridge system that snakes for 1,100 miles (1,800 kilometers) beneath the Arctic Ocean—underscore the waiting discoveries on the frontiers of Earth science. For decades scientists longingly eyed the Gakkel Ridge. But since it lies beneath a cover of sea ice, access to it has been limited. Apart from a single submarine study, much of what was known about the undersea region's geology was extrapolated from studies of other, more accessible, ocean ridges.

The temblor, measuring 4.3 on the Richter scale, sent residents running from homes and offices as Europe's highest volcano provided a grim backdrop to the panic, spewing lava and ash for a third consecutive day.

    Mexican Volcanoes About to Blow 24-May-2002 A small explosion at Mexico's Popocatepetl volcano caused a light fall of ash on Wednesday. The 17,886-foot Popocatepetl volcano has been erupting off and on since December 1994. Scientist have recorded low-level tremors within the volcano, which is 40 miles southeast of Mexico City, and several clouds of gas have escaped from its crater, according to Mexico's National Center for the Prevention of Disasters. Mexico's Volcano of Fire is spewing large amounts of lava and ash and officials warn an eruption is imminent. On Wednesday, the volcano in Mexico's western state of Colima lit...
