Mount St. Helens is a result of subduction as the Juan de Fuca Plate is pushed under the North American Plate.
The Yellowstone volcano is well withing the boundaries of the North American plate. It formed over a hot spot rather than a plate boundary.
Yellowstone is located on the North American plate, but it is nowhere the plate boundary. It is located over a geological "hot spot" and continues to have volcanic activity of one sort or another.
It is not on a plate boundary. Therefore it may be on hotspot.
It leaves an island arc or chain if the hot spot is in the ocean. A great example of this is the Hawaiian Island chain. There is another hot spot in the North American plate which now resides in Yellowstone National park. This hot spot simply leaves a chain of extinct volcanic areas as the continental plate moves over it.
Costa Rica is located on the caribian plate and it is a divergent plate boundry because it subducts under the north American
Mount St. Helens is a result of subduction as the Juan de Fuca Plate is pushed under 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.
Eyjafjallajökull is near the boundary between the North American Plate and the Eurasian Plate and is also on a hot spot.

The Hawaiian Islands are a part of the Pacific oceanic plate. Their creation is owed to a hot spot in the mantle below the crust not plate boundary volcanism.

There are several areas of concern. One is off the west coast running frm northern California to British Columbia where the Pacific Plate meets the North American Plate. Another zone is where the Pacific Plate meets the North American Plate south of Alaska and the Aleutian Islands. A third area of concern, which has triggered a tsunami recently, is near Japan, where the Okhotsk, Eurasian, Philippine, and Pacific Plates meet. Another potential tsunami may originate from a volcanic island associated with a hot spot under the African Plate.
Mount Katmai is located on a convergent plate boundary.
