How Giant Tsunamis Work?

A giant tsunami is like when you drop a huge rock into a calm pool and splash everyone around, but on a super big scale.

Imagine the ocean as a giant bathtub full of water. When something really big, like an earthquake under the sea or a volcano erupting, shakes it up, that's like dropping that rock in. The water gets pushed up into a tall wave, this is the tsunami.

Once the tsunami starts moving, it’s like a really fast runner. It can go across the whole ocean, sometimes taking hours or even days to reach faraway shores.

When it finally reaches the shore, it’s like when you pour water from a tall glass into a shallow one, the wave grows taller and wider, crashing onto land with a lot of force. That's why buildings can get swept away, and people might be surprised by how high the water comes.

Sometimes, tsunamis even come in waves, one after another, like when you drop multiple rocks into the bathtub, each one causing more splash!
