Tsunamis are a series of massive waves that ripple out from the earthquake, volcanic eruption, landslide or underwater detonation that caused them. These huge waves can travel thousands of miles across ocean basins. While out at sea, wave heights are small, but as a tsunami approaches shore, the rise of the continental slope means water levels are shallower, and the wave begins to narrow and become higher. Read below for the latest news on tsunamis and tsunami research.
A powerful 8.2-magnitude earthquake that rocked Chile Tuesday night (April 1) originated at a rupture in the Earth's crust that has produced some of the world's strongest earthquakes in history.
