The Cascadia Subduction Zone off the coast of the Pacific Northwest has all the ingredients for making powerful earthquakes -- and according to the...

6,000-year-old skull could be from the world’s earliest known tsunami victim

Tsunamis spell calamity. These giant waves, caused by earthquakes, volcanic eruptions, and underwater landslides, are some of the deadliest natural disasters known; the 2004...

Risk of tsunamis in Mediterranean Sea has been overstated

A review of geological evidence for tsunamis during the past 4500 years in the Mediterranean Sea has revealed that as many as 90 per...

Geologists determine the breadth and depth of erosion from an ancient...

When you're investigating complex questions, you've often got to dig deep to find answers. A group of UC Santa Barbara geologists and their colleagues...

High Tsunami Danger Under Alaska according to Seafloor Images

Scientists probing under the seafloor off Alaska have mapped a geologic structure that they say signals potential for a major tsunami in an area...

Sea cave preserves 5,000-year snapshot of tsunamis
