How A Tsunami Is Formed
The way a tsunami is formed from tectonic plates sliding, volcanic eruptions and underwater landslides. Then that pulls gravity up and the water goes with it above the normal sea level then crashes down with waves under water and hits the shore with a huge wave that make the tsunami. Tsunamis are very deadly as the wave get to over 100 ft high (over 30 m) and can have speeds of up to over 500 mph (over 800 kmh). There is also a trough and a crest in the waves. The trough is the lower part of a wave and the crest is the higher part. Tsunamis can go very far in shore so it would be safe to run as far and fast as possible. In some places they put walls or safety barriers.
