(a) Geological units and earthquake distribution of an oceanic subduction zone. The orange shadow beneath the volcanic arc represents partially molten areas and magma channels. (b) Thermal structure ...

Scientists have uncovered evidence that part of the planet’s crust is breaking apart in what they describe as a geological ...

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 ...

The Pacific Northwest is known for its towering trees, beautiful landscapes and breathtaking coast. But what sits about 70 miles off that coast, and anywhere from 300 to 10,000 ft below the ocean's ...

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.

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 ...

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 ...

A major earthquake along the Cascadia Subduction Zone could cause coastal land from to sink permanently, dramatically increasing the risk of flooding, according to a new study. The research, published ...

As you all know, there has been a flurry of seismic activity offshore of Sumatra the past few days, and with it a flurry of media reports. The reporting about basic stats such as location, time, ...

The supposed low viscosity of serpentine may strongly influence subduction-zone dynamics at all time scales, but until now its role could not be quantified because measurements relevant to ...
