Redeoubt volcano is part of a volcanic arc that is partially an island arc and partially a continental arc.
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
This is called a volcanic island arc.
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.

The Aleutian Island Arc is a chain of volcanic islands located in the Northern Pacific Ocean, stretching from Alaska to Russia. It is formed by the subduction of the Pacific Plate beneath the North American Plate, resulting in volcanic activity and frequent earthquakes along the arc. The Aleutian Islands are part of the larger Ring of Fire, known for its seismic and volcanic activity.
