Wasn't much compared to '80. Let one know something was happening.
At least that's so far.
As I understand it from these boards, the last time when the moisture in the earth turned to steam, the weight slid off allowing for a tremendous erruption.
There's nothing like that there. The dome, while impressive, is very small compared to the pre-'80 mass. Unless something is suddenly released from the bowels of the earth for some reason, it's hard to see how it could come up with anything like '80.
And I know sqaut about volcanoes. Been up to the top of St. Helens 10 or 12 times, but not in the last couple of years.
