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. I found this answer on answers.yahoo.com
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.
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.
It is not on a plate boundary. Therefore it may be on hotspot.

Yes. Mount St Helens is near the boundary between the North American Plate and the Juan de Fuca Plate.
subduction
Mount St Helens is on a convergent plate boundary.

Destructive plate margins, we know this because it erupts rarely yet violently and earthquakes can happen there too.
the plate boundary at the mount is a colliding plate boundary
eruasion plate
Mount Saint Helens is a product of the Juan de Fuca Plate subducting under the North American Plate.
