PPT-Algebra 1. Tsunami In the open Ocean the speed of a Tsunami is approximately:

Speed 98 x Water Depth In the open ocean the water depth averages about 4000 m a What would be the speed of a tsunami The deepest part of the oceans is the Mariana Trench which is 11035m below sea level.

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: . Waves part 2. Tsunami. Tsunami terminology.
