Formation of Tsunamis
Geography: KS3, topic 11.4.1
Tsunamis
Tsunamis are huge waves that form when tectonic activity happens on the seabed.
How do tsunamis happen?
- Tectonic activity causes water to be displaced.
- A wave starts from where the water was displaced before moving outwards.
What are the consequences of tsunamis?
- Tsunami waves do not ebb and flow like normal waves - they travel far inland before retreating.
- Tsunamis can surge up to 30 m high and cause devastation when they hit land.
