2. How do they occur? Tsunamis occur when the sea floor is shaken from an earthquake. There must be some vertical movement along the fault and it must be able of displacing huge amounts of water causing waves. The earthquake must occur near or in the ocean and be large.

Landslides can make tsunamis by the way they collapse and displace huge amounts of water and this makes waves.

3. Where do tsunamis occur? - Tsunamis occur in all oceanic regions in the world. But they mainly occur in the pacific ocean. This is because the ring of fire is in the pacific ocean. The ring of fire is a huge chain of underwater mountains, trenches, and volcanoes. All these things can cause tsunamis.

4. How fast do they move? In the deep ocean they move very fast, they go 600 miles per hour, the speed of a jet. But when they reach shallow water they slow down. On the shore it does a rapidly moving tide going at 70 miles per hour. In the deep ocean they move very fast, they go 600 miles per hour, the speed of a jet.

6. Risk to humans Tsunamis have a huge risk on humans. They could kill you if you get to close. People die by drowning and the impact of the wave. Tsunamis have a huge risk on humans.
