Geologists have discovered a second magma chamber beneath volcano They believe this feeds the smaller chamber directly below the mountain Earthquakes in the area may be a sign of magma pumping between them Geologists still consider Mount St Helens to be of high risk of erupting
Its scarred and jagged crater is a reminder of the terrible devastation that Mount St Helens wrought over the Washington countryside 35 years ago.
Now a new study of the volcanic plumbing lurking beneath the 8,363ft (2,459 metre) summit suggests the volcano could yet again blow its top in an explosive eruption.
Geologists studying the volcano, which is responsible for the most deadly eruption in US history, have discovered a second enormous magma chamber buried far beneath the surface.
This giant pool of molten rock, which lies between seven to 25 miles (40km) below the surface, is connected to a slightly smaller chamber that lies directly beneath the mountain.

Ohhh... That would work. If anyone could spill it, EPA could. Of course they would deny there is a spill until half a state is covered in lava. Then they would blame a consultant or a contractor.
Then again, they’d find a way to actually cause the super volcano.
In the photo sequence at post 14 you can see at the beginning of the sequence the huge landslide is half-way down the mountain, and was like taking out the cork of a champagne bottle.
The mountain was covered with glaciers (dark and covered with soot in the photos), but the instant heating of all that snow and ice created the huge mudflows (Lahars) that reached the Columbia River carrying homes and bridges with it.
They are still busy building new housing developments on the former mudflow deposits of Mt. Rainier. Crazy!
At this stage of my life, I'm pretty sure that's the only way I could ever get metric to mentally stick. I'd have to have some daily activity that required me to compute with that system.
My only working shortcut is to think, 'yards', whenever I hear the term, 'meters'. Close enough, I think.
Yes, a ticking time bomb.
Just multiply or divide by 6.
2 kilometers = 1.2 miles
60 mph = 100 kilometers per hour
Well, St Helens is in Washington to begin with. Portland might view that as a problem.
I heard St. Helens explode. I was on a boat in the Inside Passage. Frankly, I thought it was cannon.
Yep. You're right. I'm wrong.
Let Washington pay. Portlandia can just toke up.
The pictures are impressive. We lived here when the mountain blew. We watched all the TV reports and seen the newspapers. Did not go to see it in person.
A couple of years later my sister and husband came for a visit. She asked us to take them to see St. Helens. We were glad they did.
We thought we had seen everything. Pictures do not do it justice. Until you you stand in front of it, you have nothing to put size in true prospective.
We advise all to see it in person if they can.
BVB
Well if he was there that day, he would have been torn apart....and it wouldn't have been by love.
Thanks, but no thanks. I was born and bred in a country that speaks the English language, and which uses the standard English system of measurement.
Frankly, I'm sick and tired of bending over for the rest of the planet and their considerations, both good and bad. I'm perfectly happy with my America, the way it was originally constituted. If some folks have a problem with that, then let so be it. I'm done with bending to the will of the 'global community'.
Yeah. I have seen things that made my heart beat quicker, but...to make your knees buckle involuntarily...that has to be pure awe at the incredible force.
You must see something like that, and realize what ants we are compared to the power of nature.
