A novel three-dimensional model of the fluid stored deep in Earth's crust along the Cascadia Subduction Zone provides new insight into how the accumulation and release of those fluids may influence ...

A budding subduction zone offshore of Spain heralds the start of a new cycle that will one day pull the Atlantic Ocean seafloor into the bowels of the Earth, a new study suggests. Understanding how ...

Scientists at Oregon State University say there's new evidence that two of the best-known earthquake fault lines on the West ...

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 ...

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 ...

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 tectonic plates that form the Earth's surface are like puzzle pieces that are in constant, very slow motion – on average, they move only up to around 10 centimeters a year. But these puzzle pieces ...

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 ...

SEATTLE — Friday marks the anniversary of the last major earthquake in the Pacific Northwest when the Cascadia Subduction Zone went off 324 years ago. Since then, Washington has seen smaller ...
