The trenches form as the subducting oceanic plate is bent downward and plunges beneath the overriding plate. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. Island arc formation island arcs form on the crest of curved crustal ridges bounded on one side by deep oceanic trenches. Terrestrial island arcs or volcanic arcs are regions up to 100 km wide of subaerial and submarine volcanoes whose trenchward limit is ~120 km above the subducting plate. Examples of island arcs are the japanese islands, the kuril islands, and the aleutian islands of alaska, shown here.

Some island arcs have distributed volcanic series as can be seen in the japanese island arc. The volcanic arc represents a convergent boundary where the eurasian tectonic plates underneath indonesia converge with the australian and indian plates. The miocene volcanic complex of the takashibiyama formation consists largely of subalkali, subaqueous basalt to andesite lavas and andesite to dacite subaqueous volcaniclastic flow deposits. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. Hotspot volcanoes are considered to have a fundamentally different origin from island arc volcanoes.
