This formation of new land results from the ocean floor rising. What Happens When New Islands Form. Subduction earth movements is the cause of new underwater islands and results in a displacement of ocean water. It happens when an ocean plate slides beneath a continental plate.
Earthquakes are caused by shifts in the Earth's crust, and normally occur when rock layers move past each other along a boundary, or fault line. The surface of the land, or the sea floor, can move sideways, up, or down, and this displacement causes seismic waves to move outward, above and around the shift.
