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 else can I help you with?
What volcano is located next to a plate boundary?
Mount St. Helens in the United States is located next to a convergent plate boundary, where the Juan de Fuca Plate is subducting beneath the North American Plate. This subduction zone creates the conditions for volcanic activity to occur at Mount St. Helens.
What plate boundary does the volcano Mount St Helen in the US sit on?
Mount St. Helens sits on the Cascadia Subduction Zone, which is a convergent plate boundary where the Juan de Fuca Plate is subducting beneath the North American Plate. This subduction zone is responsible for the volcanic activity in the region.
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 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 sort of plate margin was Mount St Helens?
Mount St. Helens is located at a convergent plate boundary where the Juan de Fuca Plate is being subducted beneath the North American Plate. This subduction creates a volcanic arc in the Cascade Range.
Is the volcano of mount st Helens wa along a fault or a plate boundary?
Yes. Mount St Helens is near the boundary between the North American Plate and the Juan de Fuca Plate.
What type of plate boundary is Mount St. Helens?
subduction
Is mount st. Helen a boundary or a hot spot?
Mount St Helens is on a convergent plate boundary.
What plate boundary formed the land features of Mount Saint Helens?
Convergent

Mount St. Helens is located at a convergent plate boundary where the Juan de Fuca Plate is being subducted beneath the North American Plate. This subduction creates a volcanic arc in the Cascade Range.
What is the classification of mount st Helens?
Mount St. Helens is classified as an active stratovolcano in the Cascade Range in Washington state, USA. It is part of the Pacific Ring of Fire due to its location along the boundary of the Juan de Fuca Plate and the North American Plate.
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 plate tectonic is Mt St. Helens located on?
Mount St. Helens is located on the convergent boundary between the Juan de Fuca Plate and the North American Plate. The subduction of the Juan de Fuca Plate beneath the North American Plate is responsible for the volcanic activity in the region. This tectonic activity leads to the formation of stratovolcanoes like Mount St. Helens, which famously erupted in 1980.
