If its that high, then it was more than likely more than a VEI 4.
St Helens was said to be around 79 thousand feet.
Will see. I want to see the hole after the whole thing settles down.
BTW, the largest eruption in the 20th century was in Alaska. Novarupta, or some name like that.
I got the prelims today on that volcano.
Estimate 400 thousand tons of SO2. Blast topped out at 98 thousand feet. 400 thousand tons of SO2 is about 3% of Pinatubo.
And they are really arguing about the size of it. Some are at a 4 and some at a light 5.
Some are pissed that they cant get accurate SO2 sat images.
If it is settled at a 4, then its a hell of a 4 to send a shock wave round the earth like that. But then again it was a huge Pheartic explosion.
