How did plate movement cause the eruption of mt st Helens?

Actually, the North American Plate and the Pacific plate form a transform boundary. There is no volcanism related with a transform boundary. Mt. Saint Helens was created by the interactions of the North American plate and the Juan de Fuca plate. The Juan de Fuca plate is an oceanic plate, made of material which is more dense than continental plates, such as the North American plate. The Juan de Fuca plate and the North American plate are currently smashing into each other, and Juan de Fuca plate is subducting (sinking below) because it is denser. this allows for magma to come to the surface, and creates a volcano.

This allows for magma to come to the surface, and it creates a volcano.
