VANCOUVER, Wash. - Mount St. Helens shot a steam and ash plume at least 16,000 feet into the air Monday after a large rockfall from the lava dome in the volcano's crater, scientists said.
Pilots reported the plume rose between 16,000 and 20,000 feet in the air, scientists at the Cascades Volcano Observatory said.
The rockfall coincided with a magnitude 3.1 earthquake shortly after 9 a.m. Monday at the mountain, scientists said. Such events are expected during growth of the lava dome, they said.
"There is no evidence of an explosion associated with this event," the observatory said in a statement.
Clouds obscured the crater at the time.
"We don't know how much steam and how much ash," Cynthia Gardner, scientist in charge at the observatory, told The Columbian. "These are very short-lived events."
Lava has continued to push into the crater most recently forming a sheer rock fin since the 8,364-foot mountain reawakened with a drumfire of low-level seismic activity in September 2004.
The crater was formed by the volcano's deadly May 18, 1980, eruption that killed 57 people and blasted about 1,300 feet off the then-9,677-foot peak.

Let's face it! Helen needs a large dose of peptobismal. She has to live on the west side of the state with those liberal leftist demoncRATS. No wonder she has constant stomach indigestion.
this must be the start of "the end of civilization"
How about a glacial outwash plain? Like Anchorage.

Thanks... I love that volcano, and being a horse onwer who depends on Eastern Washington hay, I'm very familiar with the downside of a local volcano. Still, I hope she doesn't fizzle out any time soon. It's too cool to watch her go. :~D
Here is a video of the growing "fin"

Well, maybe you could just make them an island... and charge them a fortune for the ferry toll :~D
wait a sec here...."machogirl" wants a warning.....LOL!!
Nice pics, Thanks!
yes, a "helen thomas" alert
The survivor.
Maybe something like this?
Pretty safe here in PHX, No water, no faults, no oceans, no giant forests, no tidal waves.
but it can flood a bit, and its hot and that causes problems
help me out anyone?????
"this must be the start of "the end of civilization""
Actually I think that started in about 1966 or thereabouts.
