What is a Tsunami

a tsunami is a huge series of waves that rise up at sea and crash down on land.

They can basicaly get past anything. When an average sized tsunami reaches the shore it can get up to 20 meters tall! Tsunamis can speed across the ocean at 100 km/h- as fast as a jet plane. The tallest tsunami in modern times was 85 metres high as tall as the statue of liberty in new york city harbor.
