  A tsunami is a series of ocean waves that send surges (汹涌）of water, sometimes reaching heights of over 100 feet, onto land. These walls of water can cause widespread destruction when they crash ashore.
  These fear inspiring waves are typically caused by large, undersea earthquakes at plate boundaries. When the ocean floor at a plate boundary rises or falls suddenly, it displaces the water above it and launches the rolling waves that will bee a tsunami.
  Tsunamis may also be caused by underwater landslides (山崩）or volcanic eruptions. I hey may even be launched，as they frequently were in Earth s ancient past, by the impact of a large meteorite(陨石) falling into an ocean.
  Tsunamis race across the sea at up to 500 miles an hour—about as fast as a jet airplane. At that pace they can cross the entire area of the Pacific Ocean in less than a day. And their long wavelengths mean they lose very little energy along the way.
  In deep oceans, tsunami waves may appear only a foot or so high. But as they approach the shoreline and enter shallower water they slow down and begin to grow in energy and height. The tops of the waves move faster than their bottoms do, which causes them to rise steeply.
  A tsunami is usually posed of a series of waves, called a wave train, so its destructive force may be increased as successive waves reach the shore. People experiencing a tsunami should remember that the danger may not have passed with the first wave and should await official word that it is safe to return to their locations.
  Some tsunamis do not appear on the shore as massive breaking waves but instead as a quickly surging tide that floods coastal areas.
  The best defense against any tsunami is early warning that allows people to look for higher ground.
