Web30 mrt. 2024 · An island arc is a chain or group of islands that forms from volcanic activity along a subduction zone. Subduction occurs when oceanic lithosphere sinks underneath continental or oceanic lithosphere. The sinking rock melts into the magma in the asthenosphere and some comes to the surface, forming volcanoes.

The plate-tectonic concepts that developed rapidly in the late l960s made possible the understanding of island arcs. Before that time, mobilistic concepts evolved slowly, hindered, particularly in the United States, by an obstructionist geoscience establishment.
