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 ...

An international research collaboration has harnessed supercomputing power to better understand how massive slabs of ancient ocean floors are shaped as they sink hundreds of kilometers below Earth's ...

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 ...

Off the coasts of southern British Columbia, Washington, Oregon and northern California lies a 600 mile-long strip where the Pacific Ocean floor is slowly diving eastward under North America. This ...

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 ...

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 ...

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 ...
