Oceanic waves tsunami

As a tsunami traverses the ocean, a network of sensitive recorders on the sea floor measures pressure changes in the overhead water, sending the information to sensors on buoys, which, in turn, relay the data to satellites for immediate transmission to warning centers.

Anyone with a calculator can predict its speed square root of 9. The risk for tsunamis is in some parts of the world higher than in others.

Tsunamis have been relatively rare in the Indian Ocean. A tsunami can travel hundreds of miles over the open sea and cause extensive damage when it encounters land. In general, the frequency and intensity of tsunamis in the Indian and Pacific Oceans and the Mediterranean Sea is much higher than in other regions of the world.

Tsunami waves are surface gravity waves that are formed as the displaced water mass moves under the influence of gravity and radiate across the ocean like ripples on a pond.
