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, which is a 600-mile-wide fault system extending from Northern California to Vancouver Island, Canada, is the epicenter of a potentially disastrous seismic event. A ...

S. population is "somewhat likely" to experience a damaging earthquake in the coming decades, according to recently published seismic hazard models. Let's be real, most Americans think earthquakes ...

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.

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 ...

When Washingtonians talk about the possibility of a major earthquake in the Cascadia Subduction Zone, the conversation typically focuses on the immediate impacts: the threat of casualties, building ...

"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 ...

“If we don’t understand the underlying tectonic processes, it’s hard to predict the seismic hazard,” said co-author Amanda Thomas, professor of earth and planetary sciences at UC Davis. Three of the ...
