Just off the coast of the Pacific Northwest is the Cascadia Subduction Zone, a complex collection of earthquake faults ...

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 ...

The geology of the Cascadia subduction zone has largely staved off climate-related sea-level rise in the Pacific Northwest, but that could reverse in an instant.

But they can’t say exactly when the Pacific Northwest’s “Big One” could strike. The last great earthquake along the Cascadia Subduction Zone occurred in January 1700, and big events are ...

When the Cascadia Subduction Zone ruptures, it is likely to create a massive earthquake that will be felt across the Pacific Northwest. But it will also create something just as dangerous.

The Pacific Northwest is being taken for a ride. At the Cascadia Subduction Zone—a 700-mile fault that runs all the way from California to British Columbia—two giant tectonic plates are locked ...

The Cascadia Subduction Zone is a megathrust fault or the meeting of two tectonic plates. The sheer size of the fault means it is capable of producing some of the strongest earthquakes in the world.

New Cascadia Subduction Zone research suggests the tsunami risk for some coastal communities in the Pacific Northwest may not be quite as acute as originally thought.

When the Cascadia Subduction Zone ruptures, it is likely to create a massive earthquake that will be felt across the Pacific Northwest. But it will also create something just as dangerous.
