St. Helens Lava Dome: The Size Of The Carl Vinson... Almost October 21, 2004 By KOMO Staff & News Services Tools Email This Story Printer-friendly Version VANCOUVER, WASH. - The new lobe on the lava dome at Mount St. Helens has grown to about the size of an aircraft carrier. After getting a good look in the crater of the volcano in Wednesday's clear weather, the U.S. Geological Survey says the new extrusion is about 900 feet long, 250 feet wide and 230 feet high. (For comparison, the USS Carl Vinson is about 1,100 feet long, 200 feet tall and...

MOUNT ST. HELENS, Wash. -- Volcanic rock has flowed to the surface of Mount St. Helens' crater, creating a new lava dome after weeks of seismic activity, a geologist said today. Scientists had known for days that magma or molten rock was nearing the surface, as a bulge grew on the south side of the existing 1,000-foot lava dome and the increasingly hot rock gave off steam as it met water and ice in the crater. The bulge is now considered a new lava dome, the scientists said. "Now that we have new lava at the surface, we're comfortable saying"...

MOUNT ST. HELENS, Wash. (AP) - While earthquakes, steam and magma are getting all the attention on Mount St. Helens these days, the volcano's most unique feature could be the icy epitome of slow motion that has sprouted on its flanks in the last two decades: its glacier. The 1980 eruption that blew the top off Mount St. Helens also destroyed its 13 glaciers, but by 1982, the crater floor had cooled enough to allow snow to begin to stick. Now, even as the volcano stirs to life, the nation's newest glacier is growing between the lava dome and the...

MOUNT ST. HELENS, Wash. (AP) — Mount St. Helens vented more steam yesterday as new thermal images revealed that parts of the lava dome in its crater are piping hot, a sign that magma continues to rise within the volcano. Scientists said an area on the south side of the old dome, where a large uplift of rock has been growing, now appears perforated as if magma has been hammering at the surface. "The magma is not just pushing up but pushing out," John Pallister, a U.S. Geological Survey geologist, said yesterday. He said scientists believe the magma is less...

Infrared cameras surveying Mt. St. Helens have revealed a large uplifting of new magma into the crater floor. For all intents and purposes, it is now erupting. Radar may reveal any ash clouds that come out, the IR video on the local channel is quite spectacular.

Mount St. Helens in Washington state let off some more steam Monday. And new thermal images reveal that parts of the lava dome in its crater are piping hot -- a sign that magma continues to rise within the volcano. Scientists aren't sure how close to the surface the magma is. The high temperatures detected Sunday suggest the magma could be right beneath the surface or much farther down, with the heat rising because of steam spewing up from below. Heat from parts of the lava dome was so high, it exceeded scientists' instruments. Geologist Willie Scott said temperatures in...

MOUNT ST. HELENS, Wash. - Mount St. Helens vented a new column of steam Sunday, a lazy plume that rose out of the crater of the snow-dusted volcano. The billow of steam rose from an area where a large upwelling or bulge of rock has been growing on the dome-shaped formation of rock in the crater. The plume rose several hundred feet above the 8,364-foot volcano, and light wind slowly blew it toward the south and southeast. The venting reminded scientists of the volcano's activity 20 years ago, when it built the dome following its catastrophic 1980 eruption. "It's a...

Mount St Helens seems to be starting up again.

(AP) - Geologist David Johnston wouldn't have died on Mount St. Helens today. New equipment developed since the 1980 eruption of the volcano has made it possible for volcanologists to take better measurements without hiking up the volatile mountain, a requirement 24 years ago that cost...

"The Loaf" in Mount St. Helens' crater continues to cook, rising 10 to 30 feet in the preceding 24 hours, geologists said yesterday. The top of the new bulge is now slightly higher than the lava dome built up by a series of eruptions in the mid-1980s, said Jake Lowenstern, a U.S. Geological Survey (USGS) volcanologist. Magma is the driving force that has uplifted the area nicknamed "the Loaf" nearly 300 feet in the past week. But two weeks after the volcano rumbled back to life, experts remain uncertain when and how that molten rock will reach the surface. They're...

MOUNT ST. HELENS, Wash. -- Scientists said the earthquakes and explosions at Mount St. Helens could lead to an eruption as powerful as the one in 1980, KIRO 7 Eyewitness News reported. The volcano reportedly spewed more steam overnight, but earthquakes continued to be fairly light, striking about once a minute and registering about magnitude one. Meanwhile, the speculation continued about what exactly is happening underneath the mountain. Scientists said part of the lava dome in the volcano's crater has risen 50 to 100 feet since Tuesday, a sign -- along with mild earthquake activity -- that molten rock may...

Mount St. Helens' daily throes have muscled TV's disaster watch away from Florida's hurricanes and gotten the nation wondering if another monster eruption like the killer of 1980 is in store. Scientists wonder, too. But they're also keeping an eye on 13 other major active volcanoes in the Cascade Range of the Pacific Northwest, aware that Mount St. Helens isn't even the most fearsome rock on the block. That distinction goes to Mount Rainier, a 14,410-foot giant towering from 80 miles away over Seattle and its 3 million metro area residents. A year-round playground for hikers and skiers, Rainier hasn't...

Mount St. Helens Volcanic Eruptions: 1980 vs. Now Stefan Lovgren for National Geographic News October 7, 2004 It was 8:32 a.m. on May 18, 1980, in southwestern Washington State. Jim Nieland was just backing out of his driveway when a neighbor yelled, "The mountain is erupting." Nieland, a U.S. Forest Service official, sped out on the highway and looked up at Mount St. Helens. A dark cloud was forming over the volcano. Halfway to the makeshift visitors center Nieland had been running for the past two months, he pulled over at a vista point. From there he watched a...

News Home - Help Mount St. Helens' Crater Floor Rising 1 hour, 21 minutes ago By GENE JOHNSON, Associated Press Writer MOUNT ST. HELENS, Wash. - Part of Mount St. Helens' crater floor has risen 50 to 100 feet since Tuesday while earthquake rates have been low, signs that magma is moving upward without much resistance, scientists said Thursday. AP Photo   "The skids are greased," Jake Lowenstern, a U.S. Geological Survey (news - web sites) volcanologist, said at a news conference at the Cascades Volcano Observatory in Vancouver, Wash. With the latest rising, an area of the crater...

The United States Geological Service has lowered the alert level on Mt. St. Helens from a 3 to a 2. http://vulcan.wr.usgs.gov/Volcanoes/Cascades/CurrentActivity/current_updates.html For a description of the alert levels and schemes, http://volcanoes.usgs.gov/Products/Warn/WarnSchemes.html Alert level has been lowered because quake activity has dropped off.
