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.

Please disregard the first answer as it is complete and utter jank.

Why are volcanoes such as Mt St Helens on the North American plate?

Mt. St. Helens was formed when the North American Plate passed over a hot spot on the Earth's crust. A hot spot is a weak spot in the Earth's crust that magma can escape through. This hot spot is now the vent of Mt. St. Helens.
