Subduction zones, where one tectonic plate dives underneath another, drive the world's most devastating earthquakes and ...

It’s a daunting challenge with the highest possible stakes should an offshore earthquake unleash a wall of incoming seawater.

Landslides, earthquakes, and subduction faults could generate 1,000-foot mega-tsunamis, wiping coastal communities off the ...

History has a way of repeating itself. But unlike science, built on general principles and testable theories about the ...

Distant-source tsunami: More than 350 people could die or be injured along the Southern California coast if people wait to ...

This event in the Pacific Northwest could cause an unprecedented rise in sea levels that can displace land and water, sinking ...

One main goal of the exercise is to test how well they will work together to minimize loss of life and damages when a mega-quake rips along the Cascadia Subduction Zone and unleashes a killer tsunami.

The resulting sea level rise will lead to significant flood risks for huge areas of land, making recovery even harder.

The Cascadia Subduction Zone, dormant for over 300 years, poses a significant threat to the Pacific Northwest. A future ...

Adding to the threat, a major earthquake generated by the nearby Cascadia subduction zone could trigger one such tsunami that would arrive as quickly as 15-30 minutes. To address this risk ...

They emphasized that large-scale hazards — including frequent flooding in the Skagit Valley and the threat of a major earthquake along the Cascadia Subduction Zone — require federal ...

The reason is largely due to the Cascadia Subduction Zone, a massive fault running parallel to shore about 100 miles out into the ocean. There, the Juan de Fuca plate is being pushed under the ...
