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.

What’s the number one cause of death in a tsunami?

The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern. Injuries such as broken limbs and head injuries are caused by the physical impact of people being washed into debris such as houses, trees, and other stationary items.
