How they form by Felice Shoshan
How they form
The Oceanic plate and Continental plate push together. Then the oceanic plate goes under the continental plate. The earthquake pushes some of the floor up and pushes some down.The piece of the floor that is high the water goes over and makes a big wave. Then gravity evens out the water. It looks like there is no waves but there is waves under the water. They can't keep going straight because the land is in it's way. So it gets together and becomes a giant wave that wrecks everything.
How to stay safe
If you are at the beach and you see a big wave coming you should run to find high ground and get far away from the beach so you won't get hurt.
Tsunami is 2 Japanese words tsu that means harbor and nami that means wave. Tsunamis are very destructive.
