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 magnitude-7.0 earthquake struck southern Japan today, less than two days after a 6.2-magnitude temblor rocked the same region, triggering tsunami advisories in the area. Why do so many earthquakes strike this part of the world?
The 300-foot tsunami, which was triggered by a volcanic collapse, engulfed an island off the west coast of Africa some 730,000 years ago. The finding suggests similar disasters might pose a major hazard for people living on islands and coasts.
Californians may be used to hearing about the threat of potentially deadly earthquakes, but a new study finds that quake-triggered tsunamis pose a greater risk to Southern California than previously thought.
