Q. How do Tsunamis form?
A. Most tsunamis occur when two parts of Earth’s crust-tectonic plates-move below the seabed. They jolt or go underneath each other. Tsunamis can also be formed by huge rock slides or asteroids falling into the sea.
A tsunami is a train, or series, of waves. The average height above sea level of a tsunami wave as it hits a coast is 10 feet, but can be much higher. Waves from tsunamis look square when they are seen from the side. Hurricane waves are curved.
