How Does Biggest Tsunami Waves This Planet Ever Saw Work?

The biggest tsunami waves ever seen were caused by something moving really fast under the ocean, like when you suddenly drop a big rock into a puddle.

Tsunamis are like giant, fast-moving waves that come from the sea. They start with a big shake, like an earthquake or a volcanic eruption. Imagine standing on the beach and someone drops a huge boulder right in front of you, the water would splash up really high and rush toward the shore.

When the big shake happens under the ocean, it pushes the water upward. That starts a wave that moves super fast, like a train on tracks. As this wave travels across the ocean, it gets bigger and bigger, just like when you push your friend on a swing.

When the wave finally reaches the shore, it doesn’t just look big, it feels huge! The water crashes onto land like a giant wall, knocking everything in its path. It can flood cities and even destroy buildings, kind of like what happens when you spill a whole bucket of water on the floor.

Sometimes these waves are so strong that they change the shape of the coast, just like how your footprints might change the sand at the beach.
