Why do tsunami waves get so big?

The tsunami was generated by a large earthquake in the Southern Pacific Ocean. Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea. But as the waves travel inland, they build up to higher and higher heights as the depth of the ocean decreases.

All that sloping water wants to run downhill, and so it is flooding onto the land. Major tsunamis are indeed huge, but they are huge not in wave height but in volume displaced. In mid-ocean a tsunami may be only a few feet tall, but that is spread out over miles and miles in every direction.

How do tsunamis work?

What’s happening in a tsunami is a principle called water displacement, where some other force or matter takes up the room the water was peacefully occupying and sends it racing off in different directions.

When a tsunami wave approaches shore and the water gets shallower the leading edge slows down, but the miles and miles of faster wave behind it keeps coming, so only one thing can happen: the water piles up and leading edge gets higher and higher because the push from the rear keeps on coming and coming.

A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. Gotta love questions like this one.
