Ocean waves are created when energy disturbs the water. Most water waves are caused by wind blowing across the water’s surface. Tsunami waves are not like most water waves, however. The energy that creates tsunamis is a disturbance in the Earth-an earthquake. The shaking energy of an earthquake pushes the water. Tsunami waves can be more powerful than ordinary water waves, too. Tsunami waves in deep ocean waters can be huge. They can be miles long and lift up the water by about 3 feet. These waves move with the speed of a jet plane until they approach land. Then they slow down and grow taller. Scientists study tsunamis in order to be able to warn people. They use tools that measure seismic waves (地震波).

They tell how much energy is in an earthquake. Tsunamis do not happen very often, but they can be very dangerous. For your safety, know if there you live or travel is in a tsunami zone. If there is an earthquake, a tsunami could follow. So listen to a radio or watch TV for instructions. The important thing is to get to higher ground and go as far inland as you can.
