If the earthquake is powerful enough, the sudden movement of the ocean floor can cause the water above to surge upward, then fall back, resulting in a tsunami. Thrust earthquakes as opposed to strike slip are far more likely to generate tsunamis, but small tsunamis have occurred in a few cases from large i.

Similarly, because earthquake is not the only cause of a tsunami, it does not mean that when there is tsunami, there was earthquake before. A tsunami is a series of large ocean waves generated by either large earthquakes which deform the ocean floor, or landslides within or falling into the ocean. The movements cause vibrations to pass through and around the earth in wave form, just as ripples are generated when a pebble is dropped into water.
