Tsunamis Fast Facts

Here is a look at tsunamis.

Tsunamis are formed by a displacement of water – a landslide, earthquake, volcanic eruption, or slippage of the boundary between two of the earth’s tectonic plates – slabs of rock 50 to 650 feet (15 to 200 meters) thick that carry the Earth’s continents and seas on an underground ocean of much hotter, semi-solid material.

Tsunamis can travel more than 500 mph (800 k/ph) at the deepest point of the water, but slow as they near the shore, eventually hitting the shore at 20 to 30 mph (32 to 48 k/ph). The energy of the wave’s speed is transferred to height and sheer force as it nears shore.
