Hurricane Ivan created largest waves ever recorded.
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.
Underwater microphones designed to listen for nuclear explosions picked up the hiss and rumble from the tsunami-causing quake.
Uplift from the devastating 2004 quake left a detectable gash on Earth's gravity field, scientists predict.
The warning system covering the Pacific Ocean might save many lives. But nothing can stop the destruction.
Predicting major earthquakes, at least the type that produce tsunamis, may get a little easier with knowledge gleaned from a new study of past events.
Potential for devastation high based on fresh analysis of historical data since the arrival of Columbus.
The toll from the Indian Ocean earthquake and tsunami remains uncertain, with up to 142,000 still missing.
Almost all the apparent land fragmentation reported earlier is likely due to temporary flooding, experts say.
Global warming, blame for much, now is said to possibly increase the threat of a catastrophic tsunami.
