Tsunamis are usually caused by earthquakes at tectonic plate boundaries. If an oceanic plate is subducted (dragged underneath) a continental plate (a land plate) it causes friction to develop which causes the plates to stick and potential energy develops. When this energy gets too large the plates snap back in position causing sudden movement which causes water to thrust and a large wave (tsunami) to form.
