Even long-lived subduction zones eventually die, and scientists think they are witnessing the death of one in the northern ...

For generations, scientists believed that the West Coast’s two great earthquake engines — the Cascadia subduction zone and ...

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 ...

Newly-released research led by the University of Washington (UW) showed that a feature scientists hypothesized was present along the Cascadia Subduction Zone is missing in places. What does that mean ...

Researchers have discovered evidence of “partial synchronization” of two of the world’s most famous fault lines—the northern San Andreas Fault and Cascadia Subduction Zone. The relationship between ...

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 ...

PORTLAND, Ore. (KOIN) – A new study mapping the Cascadia Subduction Zone is giving scientists clues about the state of the fault line as the Pacific Northwest awaits a potentially catastrophic ...

The Pacific Northwest is known for its towering trees, beautiful landscapes and breathtaking coast. But what sits about 70 miles off that coast, and anywhere from 300 to 10,000 ft below the ocean's ...

A budding subduction zone offshore of Spain heralds the start of a new cycle that will one day pull the Atlantic Ocean seafloor into the bowels of the Earth, a new study suggests. Understanding how ...

The big one is coming. We all know that. We also know the big one might turn out to be the very big one. The 700-mile-long Cascadia subduction zone that's just off the coast of California, Oregon and ...
