The earth's crust is cracked all over,forming a number of plates.these plates are continually moving against each other,very slowly.friction can cause plates to stick.eventually,the force building up overcomes the friction and the plates shudder,creating an earthquake.if this happens under the ocean it can create a tsunami.volcanic islands,erupting violently,can dump thousands of tons of rock into the ocean creating a tsunami.In the distance past large meteors landed in the ocean,creating massive tsunamis
