Chapter 5 . Tsunami. Tsunami is a “harbor wave”. Waves rise highest where focused in bays or harbors. Tsunami have many causes. S. udden displacement of large volume of water . Earthquake. Volcanic eruptions. The name ‘tsunami’ is Japanese. . It means harbor wave. . Tsunamis used to be called tidal waves, but they actually have nothing to do with the tides.. The sudden displacement of huge amounts of water causes tsunamis. . Tsunami Mathematics. Mathematically there are three different but related factors involved in . relation . to a Tsunami.. These are SPEED, HEIGHT, and ENERGY POWER. . Tsunami Mathematics - SPEED. In the open Ocean the speed of a Tsunami is approximately: . Results from Portland State University Marine Research.
