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.

Along the ringâs edges, giant slabs of the earthâs crust, called tectonic plates, grind together. Sometimes the plates get stuck, and pressure builds.
