Webb15 apr. 2024 · A volcanic arc is a chain of volcanoes, hundreds to thousands of miles long, that forms above a subduction zone. An island volcanic arc forms in an ocean basin via … Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. They are the principal way by which continental growth is achieved.

What is the difference between island arc and volcanic arc?

WebbEarthquakes occur in the crust or upper mantle, which ranges from the earth's surface to about 800 kilometers deep (about 500 miles).
