Best Answer

Most tsunamis are generated from earthquakes at subduction zones, where one tectonic plate slide under another.

During an earthquake at such a location, the subducting plate slips forward and part of it is thrust upwards, displacing the column of water above it. This displacement of water is what becomes the tsunami.

What happens to sea waves when an earthquake is generated?

Sometimes a tsunami can occur after an earthquake has taken place. You can know when a tsunami will occur by the way the water reacts at a beach near the ocean. The water will start to pull away from the beach faster than a tide will. When this happens, the tsunami is about to strike.
