The Cascadia Subduction Zone may get most of the attention, but as Friday’s earthquakes north of Seattle show, the monster fault off the coast isn’t our only seismic threat. Western Washington is also ...

A major earthquake along a West Coast fault could have catastrophic consequences across coastal Washington, Oregon and northern California. Running offshore from northern California to British ...

It’s the 323rd anniversary of the last Cascadia Subduction Zone earthquake. We spend a fair amount of time thinking about the ‘Big One’ (and the ‘Really Big One’) in the Pacific Northwest. Today is ...

When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. west coast could shake violently for five minutes, and tsunami waves as tall as 100 feet could barrel toward shore.

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...
