The movement of the tectonic plates causes earthquakes. Nearly all of the convergent plate boundaries on the planet are located in the oceans, because the bending of oceanic plates into subduction zones causes the surface of the crust to be pulled down to several miles (several km) depth. most of the largest earthquakes occur along convergent plate boundaries when large amounts of crust move at one time. The sudden movement of the seafloor must move huge volumes of water, and this displacement of water is what causes many tsunamis.
