TSUNAMI

A tsunami is a very large sea wave that is generated by a disturbance along the ocean floor; this disturbance can be an earthquake, a landslide, or a volcanic eruption. A tsunami is undetectable far out in the ocean, but once it reached shallow water, this fast traveling wave grows very large.
Tsunamis occur when a major fault under the ocean floor suddenly slips. The displaced rock pushed water above it like a giant paddle, producing powerful water waves at the ocean surface. The ocean waves spread out from the vicinity of the earthquake source and move across the ocean until they reach the coastline, where their height increases as they reach the continental shelf, the part of the earth’s crust that slopes, or rises, from the ocean floor up to the land.



Tsunami wash ashore with of ten disastrous effects such as severe flooding, loss of lives dues to drowning, and damage to property.
