List of Tsunamis: When the Ocean Roars!

Imagine a wave so big it's taller than a playground slide, or even a school bus! That's a tsunami. These aren't like normal waves you see at the beach. Tsunamis are like a huge wall of water that rushes onto land. They can happen in oceans, but also in big lakes if something big falls in, like a giant rock or a huge chunk of ice!

People have known about these giant waves for a very, very long time. The oldest story we have is from almost 2,500 years ago! A giant wave helped a Greek army win a battle. Long before that, around 3,600 years ago, a huge underwater volcano probably made a giant wave that changed everything for people living nearby.

Most of the time, tsunamis are caused by earthquakes deep under the ocean. When the ground shakes, it pushes the water up, making a giant wave. Think of it like dropping a big stone into a bathtub – it makes ripples! But when the ocean floor shakes, the ripples are HUGE and travel super fast across the water.

One of the most famous tsunamis happened in 2004. It was so big it traveled across the whole Indian Ocean! Another happened in 2011 in Japan, and the wave was so powerful it carried cars and buildings like toys. These waves remind us how strong our planet can be!
