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.
The eruption was the most powerful natural explosion in over a century, triggering a tsunami hundreds of feet high.
The powerful earthquake occurred at 8:28 a.m. local time near New Zealand's Kermadec Islands.
A tsunami warning has been issued for Fukushima after a powerful 7.3 magnitude earthquake struck the east coast of Japan, according to Japanese government officials.
Scientists argue that we need to build better monitoring systems to spot earthquakes of this type.
A tsunami triggered by the explosive eruption of the underwater Tonga volcano in the Pacific Ocean slammed the shoreline of the Pacific nation Saturday (Jan. 15).
Some ancient islands now submerged beneath the North Sea survived a devastating tsunami about 8,000 years ago and may have played a key part in Britain's human prehistory.
