Tsunamis

Still from an animation show how seafloor features influenced the March 11 japan tsunami.
An image from an animation using satellite observations of the March 11 tsunami that shows how the waves of the tsunami were influenced by seafloor features. Wave peaks appear in red-brown, depressions in blue-green and ocean floor topography is outlined in gray. (Image credit: NASA/Jesse Allen, using data provided by Tony Song (NASA/JPL))

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.
