Tsunamis are destructive surges of water and not just a single wave, but series of ocean waves called a wave train that are caused by underwater earthquakes.

They can reach the height over one hundred feet onto land. These walls of water can cause widespread destruction when they crash ashore.

Tsunamis race across the sea at up to five hundred miles.

When reaching shore first, it produces a vacuum effect that sucks coastal water seaward.

Tsunamis is one of the most dangerous disasters caused from the ocean and can have far reaching consequences.

Tsunamis waves get stronger as they succeed and not usually the first hit is that impact as the succeeding ones.
