Volcanic islands are formed by volcanic activity on the seabed, often near the boundaries of the tectonic plates that form Earthâs crust.Where two plates pull apart, lava erupts to form an undersea ridge. Layers of lava build up until a ridge breaks the seaâs surface to form an island.olcanic islands are formed by volcanic activity on the seabed, often near the boundaries of the tectonic plates that form Earthâs crust.
1 oceanic arcs form when oceanic crust subducts beneath other oceanic crust on an adjacent plate, creating a volcanic island arc. (Not all island arcs are volcanic island arcs.). 2  continental arcs form when oceanic crust subducts beneath continental crust on an adjacent plate, creating an arc-shaped mountain belt.The term volcanic arc is often confused with the term  island arc . The former is a series of volcanoes, but not necessarily offshore. The latter is a series of islands, not necessarily composed solely of volcanoes.). Volcanoes are present in almost any mountain belt, but this does not make it a volcanic arc.
