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 ...

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Last week, about 60 miles off the coast near Ferndale, California, the tectonic plates shifted under the Pacific Ocean, sending seismic waves through the ocean floor that radiated onto land and were ...

The Pacific Northwest sits atop one of the most dangerous fault systems on Earth, yet daily life from Seattle to Portland ...

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 Cascadia Subduction Zone has been quiet for more than three centuries, yet its silence is exactly what alarms the scientists who study it. Along a 600 mile fault off the Pacific Northwest coast, ...
