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

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 ...

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 ...

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

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 ...

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 ...

Subduction zones occur where one tectonic plate dives under another. New computer modeling by Magali Billen, professor of earth and planetary sciences at UC Davis, shows why earthquakes on these ...

About 50 miles off the coast of Newport, hot, mineral-laden seawater is seeping out of the ocean floor at an unprecedented rate. Researchers at the University of Washington say the liquid acts as a ...

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth's mantle: the plate becomes weak and thus more deformable when mineral grains ...

Several billion-year-old rocks tell the story of the planet’s transition from alien landscape to one of continents, oceans, and ultimately life A new study from scientists at Scripps Institution of ...
