TSUNAMIS AND HOW THEY HAPPEN

Tsunami (pronounced soo-nahm-ee) is a series of huge waves that happen after an undersea disturbance, such as an earhquake or volcano eruption. (Tsunami is from the Japanese word for harbor wave.) The waves travel in all directions from the area of disturbance, much like the ripples that happen after throwing a rock in the water. The waves travel as fast as 450 miles per hour. As the huge waves approach the shallow water along the coast thay grow to a astonishing height and then smash with rage into the shore. They can reach a hieght of up to 100 feet. They are sometimes called tidal waves but tsunamis have nothing at all to do with the tides.
