what happens in the oceans after an earthquake?
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.
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.
