What are tsunami hazards?

A tsunami is like a really big wave that can come crashing onto land and cause lots of trouble.

Tsunamis usually happen when something really shakes the ocean, like an earthquake under the sea or a volcano erupting. It’s kind of like when you drop a rock into a pond, and it makes ripples that spread out, but with tsunamis, the "rock" is super big, so the waves are super strong.

When the wave reaches the shore, it can flood the land like water from a really fast and really high tide. It can knock down trees, wash away houses, and even carry cars out to sea, just like when you're playing in the bathtub and the water suddenly goes over the edge.

Sometimes tsunamis come in waves, one big wave might be followed by smaller ones that keep coming back, like a surprise attack from the ocean. That’s why it's important to stay safe and listen to warnings if there's a chance of a tsunami!
