Tsunamis are like giant ocean waves that happen when something big moves underwater. Imagine dropping a stone into a pond, ripples spread out, and if the stone is really big, it can make a wave that travels all the way to the shore. Scientists use special tools, like sensors on the seafloor, to know when these waves are coming so people can get ready.
Examples
- A big earthquake under the sea sends a wave that hits a beach, causing flooding.
- A landslide drops into the ocean and creates a huge wave that travels across the sea.
