Tsunami are natural disaster it usally happens after an earthquake. Tsunami are like in beach a whole water waves from he beach. It can be 30 meters TALL it is huge water.Tsunamis causes huge floods. To know when a tsunami comes uou have to be at the beach. Than when the water goes away from you. I recomend people should not investigate.

I would recomend run away from the beach because it will be on the way. To know how big it is gonna be. It depends on how fast the earthquake was because that everything shakes when there is an earthquake. So than under the water it starts to shake so it is getting bigger and bigger. So I think all kids and adult or old people should not go near one.

Look at the picture before this page. This is what it looks like off it getting bigger.

It can be 75 persont tall. thats it all about tsunami
