Mt St.Hellens is going to BLOW !

No need to be afraid. Mt. St. Helens is still building up.

After its done nestling itself a new dome, it'll most likely go back to sleep for more than a century.
 
Someone mentioned something in reference to the Long Valley caldera. Tell me about it.
 
They've raised the threat level to 3, and evacutated people from the area.

They are also saying that on a scale where Friday's steam eruption rates a zero, and the 1980 eruption rates a 5, we could get something as large as a 3.

Not comforting considering that I live in Portland, only 55 miles from the mountain. It means that if the prevailing winds are right, we could get a dose of ash.

Not conforting for me either, cuz I have family in Gresham, Sandy, and Vancouver, WA - all roughly within the same 55-mile radius.
 
I can't believe there's enough magma beneath the mountain at this point to cause anything like the 1980 blast: and even if there were, it has far less of a mountain capping it off this time. The magma will escape without having to build up such a tremendous pressure, and therefore the eruption will not be as sudden or as explosive. More likely a series of smaller pyroclastic eruptions - still deadly in the immediate area, of course.

It would be a shame, seeing how rapidly and efficiently nature has reclaimed the area since the big blowout, if the new ecological succession were put back to square 1 so soon.

One hopes to visit the Mount St. Helens National Volcanic Monument in old age, and see it restored to the thriving primary forest it was before 1980.

Alas, that's the flow of life. Birth, Death, and Renewal. It's an endless, unstoppable cycle.

It depends, Though a blast of that magnitude is on the extreme end of likelyhood, we could still get ash eruptions large enough to spread ash over a considerable area. We got one such eruption just one week after the May 18th eruption. With the East wind on that day, we got an ash dusting all the way to the coast. And believe me, even a light dusting of volcanic ash can cause a lot of headaches.(For me it literally caused one big one!)
 
I may be stating the obvious, but earthquakes in such a region are not always the precusors to volcanic activity.

The zone of activity certainly would not stop at Washington State border, since the subducting Juan de Fuca plate extends much further north.
 
Actually we have some volcanoes here in B.C. and tonnes of underwater volcanoes as well!
There are Hot springs all over the palce here and a Big scalding hot one in Tofino!

Another venting today at St.Hellens. I am still waiting for Krakatowa!

Oh, you don't want Krakatau. One of the worst volcanoes EVER.
 
I'd like to have seen Thera explode back in Minoan times (the END of that civilization, actually!) From a safe distance, of course.
