Earthquakes and a Tsunami

When a tsunami hits the land it can make terrible damage to the land and the people. it can sweep the house’s and people and the cars.A tsunami can not be stopped.Because we do not know how the tsunami starts it is so difficult for them to warn the people . Cities and towns can be destroyed by the power from the water .

When an earthquake happens under the water,the shock waves make the water move in big and strong waves.The waves spread out from the epicentre and travel over long distances. Near the coast the waves slow down and from  into  one huge wave. it is a tsunami.
