MOUNT ST. HELENS, Wash. - Mount St. Helens made its most significant emission in months, sending a gritty ash cloud drifting slowly to the northeast.

Mount St. Helens bursting with ash Last Updated Tue, 08 Mar 2005 21:51:46 EST CBC News SPOKANE, WASHINGTON - Mount St. Helens in Washington state has erupted, sending a plume of steam and ash 7,600 metres into the air. Government scientists say they measured an earthquake of magnitude 2.0 beneath the mountain when the first plume of smoke went up Tuesday. The volcano has been active in previous months. A minor eruption lasted 24 minutes last October, sending up 3,000 metres of steam and ash. The U.S. Geological Survey detected magma moving below the surface, along with the increased presence...

SEATTLE (AP) — Growth of the new lava dome inside the crater of Mount St. Helens has gradually slowed and become less steady since it began in early October, scientists from the Cascade Volcano Observatory said Tuesday. "The rate of dome growth has slowed since early October and the area in the crater that was deforming was (changing) much faster in early October than it is now," U.S. Geological Survey research hydrologist Jon Major said in a telephone conference update. Molten rock has been oozing out from the surface of the volcano's crater since October, building a new lava dome...

KING 5 news is reporting that the instruments on Mt. St. Helens have ceased transmitting data. They say it could be due to a steam eruption, or a rock slide, some kind of major event. Indications are that right before they stopped, the lava dome was growing at a very rapid pace.

SAN FRANCISCO -- An unusually smooth and swiftly growing lava dome within the crater of Washington state's Mount St. Helens volcano is an extraordinary and perplexing event with an unknown outcome, geologists said Tuesday. When Mount St. Helens blew its top in 1980, it left a mile-wide crater. Over the next six years, a dome of lava built up in the middle of the crater. Then the volcano went quiet. The dome became partly buried by a glacier that's more than 600 feet deep in places. Read rest at : http://www.livescience.com/forcesofnature/041215_msh_update.html

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 firm TransAlta. The plant churned out 200 tons a day of sulfur dioxide until regulators demanded $250 million...

Environmentalists hooted when Ronald Reagan claimed — wrongly — that trees produce more pollution than cars. But right now, the biggest single source of air pollution in Washington isn't a power plant, pulp mill or anything else created by man. It's a volcano. Since Mount St. Helens started erupting in early October, it has been pumping out between 50 and 250 tons a day of sulfur dioxide, the lung-stinging gas that causes acid rain and contributes to haze. Those emissions are so high that if the volcano was a new factory, it probably couldn't get a permit to operate, said...

AN FRANCISCO, Nov 27 (Reuters) - A minor 3.1 magnitude earthquake split the lava dome in the crater of Mount St. Helens on Saturday, continuing a series of minor earthquakes rattling the site since October, the U.S. Geological Survey (USGS) said. The mountain -- which in 1980 blew up with the eruption of a huge and deadly volcano -- has been spewing ash and steam since early October in a process of building a new lava dome, according to a USGS report. The historic mountain has been closed to all climbers and visitors because of the emissions. "Steam and gas...

YAKIMA, Wash. -- That whaddyacallit that's growing on Mount St. Helens - what DO you call it? Even Shakespeare himself might have trouble figuring out what's in a name. It's been called the "blister," "wart," "thing" and "lobe" since it appeared last month in the crater of the reanimated Mount St. Helens volcano. One researcher referred to it as "an uplift," before most everyone in the know agreed it must be a dome. Naming the dome - now about the size of an aircraft carrier - could be another matter altogether. In one meeting, a scientist threw out a suggestion:...

MOUNT SAINT HELENS, Wash. - The new lava dome inside the crater of Mount Saint Helens 50 miles north of Portland has grown a protrusion the size of a 30-story building that glows red at night. Scientists from the U.S. Geological Survey released dramatic new video of that growth. Night video shows the hot lava dome glowing red. Scientists say it is the result of rising magma, or molten lava. The lobe began building up last month and has grown to the size of an aircraft carrier. One section has risen 330 feet in the past ten days. Scientists still...

The new lava lobe inside Mount St. Helens' crater has sprouted a piston-like protrusion the size of a 30-story building glowing red at night. "The magma is pushing the plug upward. It's going high in the sky," said hydrologist Carolyn Driedger of the U.S. Geological Survey at the Cascades Volcano Observatory in Vancouver, about 50 miles from the southwestern Washington mountain. One section of the new lobe has risen by 330 feet in the past nine days, Driedger said Friday. Exact dimensions are not yet known but will be determined from photos taken Thursday. "It seems like every time you...

I just took a peek at Mount St. Helens Volcano Cam and was surpised by an image of steaming or smoke coming out. I have been unable to get a clear view for several days now because the image was all fogged up. There were no news reports that I could find posted yet today. Take a peek if you are curious. Volcano CamWhat ever. Oh, well . . .

10/26/2004, 3:37 a.m. PT The Associated Press KALAMA, Wash. (AP) — Along the Kalama River, locals say they know something the volcanologists don't, that when the water turns milky white it means Mount St. Helens may be about to blow. Elwin Bottorff, 76, a retired lumber mill manager, says he has been reading the river that runs past his front yard for 40 years and knew what it meant the last time he saw the change. "The first thing I said was, 'That goddamn mountain is screwing around again,'" Bottorff said. "Then, sure enough, about a week later, here it...
