A tsunami is a very large ocean wave caused by an earthquake under the sea.

Tsunamis are formed when an earthquake happens under the ocean, and the energy from the earthquake creates big waves.

I can describe what a tsunami is and how it is formed.

1
Tsunamis are often more devastating than earthquakes because the waves can travel up to 16 kilometers on land.
2
Tsunamis are caused when an earthquake's seismic waves have a repercussion on the water.
3
Tsunamis usually have a wave train, where four or five waves may occur after the initial wave hits.
