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

One of the most dangerous faults in the United States, the Cascadia Subduction Zone, may be able to trigger an earthquake on the San Andreas Fault, a new study says. But some scientists want more ...

Two earthquakes struck off the Oregon coast on Tuesday, rattling communities along the Pacific Northwest shoreline.

On Wednesday morning, a 5.4 magnitude earthquake rattled the waters off the coast of Oregon, approximately west of Newport. The tremor occurred around 6 a.m. and was reported by the U.S. Geological ...

For the first time, scientists have seen a subduction zone actively breaking apart beneath the Pacific Northwest. Seismic ...

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 ...
