SEATTLE — 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 ...

A megathrust earthquake is coming for the Pacific Northwest. But new imaging of undersea faults and fractures has given scientists even more information about the tectonic plates that will cause that ...

Deep-sea landslides in the Pacific Northwest's Cascadia subduction zone hold a record of earthquakes dating back 7,500 years, and similar markers may be found in other tectonic plate boundaries ...

The Cascadia Subduction Zone is unusually quiet for a megathrust fault. Spanning more than 600 miles from Canada to California, the fault marks the convergence of the Juan de Fuca and North American ...

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.

The Cascade Subduction Zone affects where the ocean meets the land, and that land is rising in some parts of the Oregon Coast.

"What we looked at was kind of lesser though and lesser-known consequences of the next earthquake, which is the land subsidence, or the way the land is going to drop down," said Dr. Tina Dura, the ...

This map models locking at the Cascadia Subduction Zone, with red showing where the plates are tightly locked and orange/yellow indicating less locking. The study sites are marked with small red ...
