Mount St. Helens was formed along a subduction zone, where the Juan de Fuca Plate plate dives under (subducts) the North American plate.
Mt. St. Helens is in a subduction zone, the subduction of the Pacific Plate under the North American Plate.
No. Mount Tambora formed along a subduction zone.
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
Mount Saint Helens in Washington USA is at a convergent boundary
Mount Saint Helens is part of the Cascade Range.
Harry Randall Truman (not to be confused Harry S. Truman) was an elderly man who lived in a lodge near the foot of Mount St. Helens. He became something of a celebrity when he refused to leave despite warnings from scientists. Truman died along with 56 other people when Mount St. Helens erupted on May 18, 1980.
No. Mount Tambora formed along a subduction zone.

They are both found along the Cascadia subduction zone
Yes. Mount St Helens is near the boundary between the North American Plate and the Juan de Fuca Plate.
Indications that a mountain range was not formed by subduction include the absence of deep oceanic trenches, lack of volcanic activity, and the presence of diverse rock types that are not associated with subduction zones. Additionally, the orientation of the mountain range may not align with the typical pattern of subduction-related mountain building.
there are no volcanoes it is not along an ocean coastline

Mount Merapi was formed by two converging plates. Subduction causes slabs of oceanic crust to sink through a deep-ocean trench into the mantle. The crust melts and forms magma, which then rises back toward the surface. It is located along the Sunda, or Java trench. When the magma from the melted crust erupts as lava, volcanoes are formed. Mount Merapi is located along an island arc.
It is not along an ocean coastline. There are no volcanoes.
