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. The subduction results in the creation of undersea volcanoes which then rise above sea level. The resulting volcanoes create a string of islands called an island arc. The curve of an island arc echoes the curve of its deep-ocean trench.

What is the differences between volcanic island arcs and volcanic arcs?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.

What three major island arcs?
Island arcs are also called oceanic arcs. Many volcanoes form near converging plate boundaries where subduction occurs. Subduction causes slabs of oceanic crust to sink beneath a deep-ocean trench into the mantle. The crust melts and forms magma, which then rises back toward the surface. Volcanoes form when the magma erupts as lava. At the boundary where two oceanic plates collide, volcanoes can create a string of islands called an island arc. There are many island arcs. The main ones that we read of most often include Japan, New Zealand, Indonesia, Caribbean Islands, Philippines, and the Aleutians.
