Tsunamis

Some seismologists think Japan is still feeling the aftershocks of the 2011 Tohoku earthquake.

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.

A 7.8-magnitude earthquake struck off the coast of Sumatra, an island in western Indonesia, according to the U.S. Geological Survey (USGS).

There are many ways to go, but what are the odds, really?

Sometime in the past 8,000 years, a meteor may have hit the Indian Ocean, triggering a monster tsunami that struck Africa, a new study suggests.

A network of undersea faults off the coast of Southern California could produce huge quakes that could send tsunami waves crashing into Los Angeles, new research suggests.

Indian Ocean tsunamis destroyed one of the world's most important silk-route ports in the 15th century, new research finds.

The 2011 Japan tsunami released thousands of tons of ozone-destroying chemicals and greenhouse gases into the air.

A new simulation predicts that relatively small asteroids could cause big waves on the U.S. coastline, but not everyone thinks the threat is real.

Ten years ago we witnessed one of the worst natural disasters in history, when a huge earthquake off the coast of Sumatra triggered a devastating tsunami which swept across the Indian Ocean.

As the 10th anniversary of the Indian Ocean tsunami approaches on Dec. 26, greatly expanded networks of seismic monitors and ocean buoys are on alert for the next killer wave.

Small islands boost the power of tsunami waves, rather than absorbing their impact, a new study shows.
