Most composite volcanoes have a crater at the summit which contains a central vent or a clustered group of vents.

A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in a volcanic island arc.Generally they result from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.olcanic arcs do not generally exhibit such a simple age pattern. There are two types of volcanic arcs: 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.).
