Answer:
A tsunami is a natural disaster which is a series of fast-moving waves in the ocean caused by powerful earthquakes, volcanic eruptions, landslides[2], or simply an asteroid or a meteor crash inside the ocean. 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 earth's surface, though it is very rare. A tsunami normally occurs in the Pacific Ocean, especially in what is called the ring of fire, but can occur in any large body of water.
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.
Tsunamis are often called tidal waves because they usually rise and fall more slowly than ordinary ocean surface waves. This name is misleading, because tsunamis are not related to tides; they merely rise slowly is a series of fast-moving waves in the ocean caused by powerful earthquakes or volcanic eruptions.

Explanation:
it very large wave in the sea which destroys things when it reaches the land, and is often caused by movements under the surface of the earth (an earthquake)
The effects of a tsunami on a coastline can range from unnoticeable to devastating. ... However, when tsunami waves become extremely large in height, they savagely attack coastlines, causing devastating property damage and loss of life
