A tsunami is a series of waves caused by earthquakes or undersea volcanic eruptions. ... Out in the depths of the ocean, tsunami wavesdo not dramatically increase in height. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.
Most tsunamis are caused by earthquakes. An earthquake occurs when a large area of the Earth's crust suddenly moves. When this happens underwater, big gaps may appear on the ocean floor. When water moves in to fill this gap, a tsunami is born.
A tsunami is a series of ocean waves that sends surges of water, sometimes reaching heights of over 100 feet (30.5 meters), onto land. These walls of water can cause widespread destruction when they crash ashore.
How do tsunamis occur? Tsunami are actually waves caused by sudden movement of the ocean due to earthquakes, landslides on the sea floor, land slumping into the ocean, major volcanic eruptions or large meteorite impacts. ... the top of an underwater volcano may collapse downwards, so that the overlying water also drops.

What is the disaster of a tsunami?

A tsunami (pronounced su-nah-me) is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis.
