What is the fault type and magnitude of mt saint helens?

Question

do you have any sites

Answer 1

You probably won't find many sites on the fault types of Mt. St. Helens.  Mt. St. Helens is a Stratovolcano and most faulting assoicated with the mountain is in response to eruptions.

Earthquakes associated with eruptions of volcanos are usually very locaized.  Naturally if a big stratovolcano blows its top most seismic recorders will easily pick that up.  Magnitudes will depend on the size of the eruption and can range from less than 2 to more than 7 on the Richter Scale depending on the size of the eruption.
