Earthquakes commonly occur in the ocean and can range from small trembles to as high as 9.2 on the Richter scale. Strike-slip, dip-slip and subduction are the three types of earthquakes. Strike-slip eartquakes occur when the ocean floor moves back and forth. Dip-slip earthquakes happen when the ocean floor moves up and down. Subduction earthquakes form when plates of the earth's crust stack on top of one another.
