Why is a tsunami so powerful?

The power of a tsunami comes from straightforward physics. An earthquake suddenly pushes part of the sea floor up or down. That changes the height of the water above it — what physicists call potential energy — and the potential energy quickly changes into the kinetic energy of the tsunami waves.

Why did 2004 tsunami kill so many?

According to USGS scientists, the sea floor near the earthquake was uplifted several meters. The displacement of water above the sea floor triggered the tsunami, which caused catastrophic levels of destruction in countries around the Indian Ocean basin, reaching as far as the east coast of Africa.

Can the force of a tsunami kill you?

Tsunamis are harmless for 95% of their life. The energy of the tsunami runs through the entire depth of the ocean. It only becomes deadly when the ocean floor becomes shallow, and all that energy compresses into a smaller amount of water. Tsunamis move at the speed of a commercial airliner (about 500mph).

Can a person survive a tsunami?
