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.
Extinct volcanoes on the ocean floor get squashed by tectonic plates and create tsunami earthquakes.
A team of scientists ventured to the depths of the Caribbean Sea on a three-month voyage to study fault zones and strange biological communities.
The Caribbean usually conjures images of white sandy beaches and sparkling turquoise water, but beneath the sea's tranquil surface, powerful forces are at work.
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.
A monster earthquake in Alaska could trigger 5-story-high tsunami waves that would inundate some of Hawaii's most iconic beaches and its critical power infrastructure, new research suggests.
Strong waves associated with a low-end derecho that hit the area in mid-June indicate a possible meteotsunami.
