What causes the sun's 11-year cycle of sunspot activity? According to two new studies, it could be literal tsunamis of plasma.
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.
More than 1,200 are estimated to be dead after a powerful earthquake and tsunami ravaged the Indonesian island of Sulawesi.
The corpses of these tiny creatures ooze out a slimy layer that may explain catastrophic undersea landslides and tsunamis.
A 7.9-magnitude earthquake struck off Kodiak, Alaska, this morning. A tsunami warning is in effect for parts of Alaska and British Columbia, Canada.
A 6,000-year-old skull found in what is now Papua New Guinea may be the first evidence of a tsunami victim.
A so-called seismic zone off the coast of Alaska could trigger deadly tsunamis like the one that caused the Fukushima nuclear disaster in Japan in 2011, a new study finds.
A complex computer simulation has modeled the impact of an asteroid in the ocean and the results may surprise you.
A magnitude-6.9 earthquake struck off the coast of Fukushima, Japan, today (Nov. 21), triggering a tsunami warning.
The quake's epicenter is northeast of Christchurch, but was felt as far as New Zealand's capital Wellington, located 120 miles (200km) away on the North Island.
The eruption of Thera did more than blow a hole into the island and trigger tsunamis and flooding, it also set off the decline of the Minoan culture.
