Mt. St. Helens

VANCOUVER, Wash. - Rockfall at Mount St. Helens kicked up a dust plume Tuesday that rose above the rim of the volcano's crater, drawing attention in the region.

 

 

"It's a nice sunny day and we're having the first couple of rockfalls that we've had in a while that are putting little dust plumes over the crater rim," said U.S. Geological Survey geologist Seth Moran at the agency's Cascade Volcano Observatory here, about 50 miles south of the mountain that erupted to deadly effect in May 1980.

 

Seismic activity has continued at low levels, Moran said.

 

The white plume floating above the peak was raising concerns locally.

 

"When rockfalls go down they kick up a dust plume and people can see it — especially from Portland," Moran said.

 

Overcast weather had hidden the mountain for weeks.

 

"Any time you go through a pause" during which the mountain is not visible, people notice activity more when the peak comes back into view, Moran said.

 

Mount St. Helens rumbled back to life in September 2004 after years of quiet. In October a flow of molten rock reached the surface, marking a renewal of domebuilding activity that had stoppped in 1986.

 

The 1980 eruption killed 57 people, flattens forests and sent a river of hot mud and ash down the Toutle River Valley.

 

USGS and the University of Washington continue to monitor the mountain.

 

Scientists say a more explosive eruption, possibly dropping ash within a 10-mile radius of the crater, is possible at any time.

Not good, then again they think the super volcano under the Yellowstone National Park is thought to be refilling!

 

But with most things in science if it happens once then itwill ahppen again, its just a matter of time....

I'm sorry that I did not see this post earlier because this is probably a more appropriate place to post this link. Here, you can see visual updates of Mt. Saint Helens from the perspective of the Johnston Ridge Obervatory. It's refreshed every five minutes and provided more vivid pictures of the dust coming out of the crater than I can get with my binoculars from Kansas.
