Web about five percent of all known volcanoes form in the middle of plates, not at their edges. Web the volcanoes produced by subduction zone volcanism are typically stratovolcanoes. These intraplate volcanoes are caused by hot spots, unusually hot areas deep within. A volcanic arc is a chain of volcanoes, hundreds to thousands of miles long, that forms above a subduction zone. Web island arcs are formed from the subduction and melting of oceanic crust as it descends into the mantle underneath a less dense oceanic crust at a convergent plate boundary.
