MOUNT ST. HELENS NATIONAL MONUMENT, Wash. (AP) -- The four, their lungs filled with ash, were found inside their car after Mount St. Helens erupted on May 18, 1980, with the force of a hydrogen bomb. Rescuers also discovered a cassette recorded by Ron and Barbara Seibold's children, ages 7 and 9, as the family drove toward the volcano. "They were goofing around - asking whether or not they would see lava coming out of the mountain," said Jim Thomas, an emergency worker at the time. "One...

ORTING, Wash. (AP) -- In the shadow of Mount Rainier in Washington, people go about their lives - going to shop, going to school, going to work. One day, though, the routine will be broken by a rumble that sounds like a thousand freight trains. If all works accordingly, sirens will alert the 4,400 residents that they have less than 45 minutes to evacuate - or be buried by an avalanche of mud and debris tumbling off the flank of the 14,411-foot volcano. Scientists know Mount Rainier will...

YELLOWSTONE NATIONAL PARK, Wyo. (AP) -- The Yellowstone caldera has been classified a high threat for volcanic eruption, according to a report from the U.S. Geological Survey. Yellowstone ranks 21st most dangerous of the 169 volcano centers in the United States, according to the Geological Survey's first-ever comprehensive review of the nation's volcanoes. Kilauea in Hawaii received the highest overall threat score followed by Mount St. Helens and Mount Rainer in Washington, Mount Hood in...

MOUNT ST. HELENS NATIONAL MONUMENT, Wash. (AP) -- Johnston Ridge Observatory reopened to the public Friday, seven months after it was closed because of new activity at Mount St. Helens. From the observatory, visitors can look five miles into the crater of Mount St. Helens where a steaming lava dome has been growing since October. On Friday, however, clouds obscured the view. It may be a couple of days before the weather clears enough for visitors at the observatory to get a better view of...

WASHINGTON (AP) -- While Mount St. Helens and Kilauea generate the most attention, many other volcanoes in the United States have little or no regular monitoring and need to be watched for potential eruptions, a new report warns. The U.S. Geological Survey said Friday that monitoring gaps exist for volcanoes in Alaska, California, Washington, Oregon, Hawaii, Wyoming and the Northern Mariana Islands that could pose a hazard both on the ground and to aviation. The report reviews the hazard of...

MOUNT ST. HELENS, Wash. (AP) -- Surging seismic activity at Mount St. Helens has changed the whale-back shape of the volcano's emerging new dome, leaving it more like the back of a stegosaurus - a dinosaur with bony plates of armor along its spine. The outer edge of the jagged, plate-like protrusions matches the smooth old whale-back profile, so it appears the new look reflects a sinking away of some segments of the dome, said David Sherrod at the U.S. Geological Survey's Cascades Volcano...

VANCOUVER, Wash. (AP) -- Scientists at the U.S. Geological Survey's volcano observatory here were getting ready to head home when the squiggly line on the computer that tracks seismic activity at Mount St. Helens suddenly turned a solid black. "It just kept on going and going and going," said research hydrologist Jon Major, describing the seismic line that registered Tuesday's earthquake measuring a magnitude of 2.0. Outside the building, the mountain located some 50 miles away was belching...

SEATTLE (AP) -- Growth of the new lava dome inside the crater of Mount St. Helens has gradually slowed since the mountain reawakened in October, scientists said Tuesday. Molten rock has been oozing out from the surface of the volcano's crater since the fall, building a new lava dome that now has a total volume of 44 million cubic yards. That is big enough to contain 134 buildings the size of the basketball arena where the Portland Trailblazers play. Scientists provided an update on Mount...

SEATTLE (AP) -- Washington state's top polluter isn't a pulp mill, a power plant or refinery. It's the newly awakened Mount St. Helens. Since the volcano began erupting in early October, it has been pumping out 50 to 250 tons a day of sulfur dioxide, the lung-stinging gas that causes acid rain and contributes to haze. At peak, that's more than double the amount from all the state's industries combined. Normally, the state's No. 1 polluter is a coal-fired power plant owned by the Canadian...

MOUNT St. HELENS (AP) -- A 3.1-magnitude earthquake shook the crater at Mount St. Helens on Saturday, the strongest quake at the volcano since mid-October. U.S. Geological Survey scientists said they did not believe a major eruption was imminent - just a continuation of the minor ash and steam eruptions that have been occurring since the mountain reawakened this fall. Saturday's earthquake appeared to be a larger version of the small earthquakes scientists have registered about once a...

Socompa is a complex stratovolcano that can be found at the border of Chile and Argentina, reaching an elevation of 19,852 feet. This volcano is best known for its avalanche debris deposit, which have formed the Monturaqui Basin on its west side, the most noted example of this type of deposit in the world. It is a difficult volcano to visit, taking at least a day by vehicle traveling from the north or the west. Socompa is also known for the microbial ecosystems that occur near grasses at its...
