An ocean earthquake commonly occurs between 200 and 1,000 years. As the pressure of floating plates bouncing against a continental plate rises, the continental plate starts pushing back. This causes an ocean floor island to recede underwater until the pressure is too great.
Water in the sinking plate eventually leaves the crust and rises into the wedge of the mantle above it. As a result the mantle practically melts. The magma that forms as a result rises up. This magma can break through the ocean floor, causing an island arc. The curve of the island arc imitates that of a mid-ocean trench. Also where oceanic plate is subducted under continental.
