Question

What is Tsunami ???Explain

Answer 1

A Tsunami is a progression of expansive waves produced by an unexpected development on the sea depths that can result from a seismic tremor, a submerged avalanche, a volcanic ejection or - once in a while - a substantial shooting star strike. Be that as it may, incredible undersea seismic tremors are in charge of generally tidal waves.

Answer 2

A tsunami is a series of fast moving waves in the ocean caused by powerful earthquakes or volcanic eruptions. A tsunami has a very long wavelength. It can be hundreds of kilometers long. Usually, a tsunami starts suddenly. The waves travel at a great speed across an ocean with little energy loss. They can remove sand from beaches, destroy trees, toss and drag vehicles, houses and even destroy whole towns. Tsunamis can even be caused when a meteorite strikes the earths surface, though it is very rare.

The water often draws back from the seacoast half of the wave period prior to the wave getting to the coast. If the slope of the coast is not deep, the water may pull back for hundreds of meters. People who do not know of the danger often remain at the shore.

Tsunamis cannot be prevented. However, there are ways to help stop people dying from a tsunami. International and regional warning systems, especially for the Pacific Ocean, issue alerts before the big waves reach the shore. Because an earthquake that caused the tsunami can be felt before the wave gets to the shore, people can be warned to go somewhere safe.
