The cause of Mt. St. Helens' volcanism is due to the subduction melting of the Pacific Plate as it subducts under the North American Plate, located along a convergent plate boundary or fault.
No, Mount Saint Helens is not on a hot spot, nor is it on a fault. Mount Saint Helens is part island arc volcanic chain (the Casade Mountaind) due to the subduction of the Pacific Plate under the North American Craton.
NOTE: The Farallon Plate is no longer here; it ceased to exist with the end of the Laramide Orogeny some 30 million years ago. The remnants of the Farallon Plate are the Juan de Fuca Plate of British Columbia and northwestern Washington state, and the Cocos Plate of southwestern Mexico. Neither of these microplates has any effect on Mount Saint Helens, which is in southwestern Washington.

What type of tectonic plates does mount st helens have?
On a continental plate. Mount Saint Helens is on a convergent plate boundary. The Juan de Fuca plate is being pushed under the North American Plate.
What plate boundary does the volcano Mount St Helen in the US sit on?
Mt. St. Helens is located on a convergent boundary between the Juan de Fuca and North American plates.Mount st. Helens is on a convergent boundary.
What divergent boundary convergent boundary or hot spot is Mount Fuji over?
It is not on a plate boundary. Therefore it may be on hotspot.
What plate boundary is mt rainier on?
Mount Rainier, Washington, isn't located on a divergent plate boundary but a convergent one. The Juan de Fuca Plate off the coast is pushing under the northern US and Canada, creating volcanism (such as Mt St Helens).

What divergent boundary convergent boundary or hot spot is Mount Fuji over?
It is not on a plate boundary. Therefore it may be on hotspot.
What plate boundary does mount saint helens sit on?
Destructive plate margins, we know this because it erupts rarely yet violently and earthquakes can happen there too.
What plate boundary is mt rainier on?
Mount Rainier, Washington, isn't located on a divergent plate boundary but a convergent one. The Juan de Fuca Plate off the coast is pushing under the northern US and Canada, creating volcanism (such as Mt St Helens).
Is mount kilauea convergent?
No. Kilauea is not associated with a plate boundary. It is caused by a hot spot.
