If it is a single island, it is simply known as a volcanic island! If however it is a chain or string of separate islands then it may be a volcanic island arc (these form parallel to trenches at subduction zones) or a volcanic island chain (these form where a mantle plume creates a hotspot and may be in the centre of a tectonic plate. A good example would be the Hawaiian island chain). They can also form a cluster of islands (an archipelago) such as the Canary Islands (again formed by hotspot volcanism) in the Atlantic of the coast of Morocco.
The Canary Islands which are situated in the Atlantic off the western coast of southern Morocco.
Volcanic action. The island is called Surtsey.
Surtsey is a volcanic island off the southern coast of Iceland. It is the southernmost point of the island country.
If you mean the eastern shore of the U.S., yes. There is a volcanic island off Africa's Atlantic coast called Cumbre Vieja. There is some concern that in a future volcanic eruption the western flank of the island could slide into the ocean, triggering a massive tsunami that could potentially devastate the U.S. east coast.
off the southern coast of Iceland, formed by volcanic eruption in 1963
Constructive
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 small island off the south coast is called "Sandy Cove Island."
