I think its a chain of volcanoes form when oceanic crust subducts beneath other oceanic crust on an adjacent plate. Hope this helps (:
When it was formed by the movement of tectonic plates as a volcanic island.
Atolls are formed first as a reef that fringes a volcanic island. The two largest atolls are Suvadiva in the Maldives Island and Kwajalein in the Marshall Islands.
Mount Vesuvius is located on what is known as the Campanian Volcanic Arc. Mount Vesuvius erupted in 79 AD and caused the destruction of Pompeii.
Destructive because the water pulls the beach apart. At one point the beach was just rock but the ocean beat it up so now it's soft.

Redeoubt volcano is part of a volcanic arc that is partially an island arc and partially a continental arc.

This is called a volcanic island arc.

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.

A chain of volcanoes is called a volcanic 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.
The definition of the word island arc is " a curved chain of volcanic islands located at a tectonic plate margin, typically with a deep ocean trench on the convex side."
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.
