Maybe it will act as a safer relief valve for preventing a bigger one over at Yellowwtone National Park. Do these eruptions do that sort of thing?
Only if the underground plumbing is related.
Yellowstone is a hotspot, St Helens is related to descending plate melt.
Now, Iceland, Katla and a few other volcanic spots are related, and a pop at one usually signals another soon to go.
Only God knows.....................
Not even close. Yellowstone is over a hot spot, Helen is a subduction zone generated volcano ( and you know, Subduction leads to Orogeny!)...
