The Cascadia Subduction Zone looks a little different than researchers thought. Here's what that means for "The Big One." ...

A subduction zone is created where two plates converge, with one sinking into the mantle. Dynamics along the plate interface create earthquakes, magma generated above the sinking slab leads to ...

The Cascadia Subduction Zone is a 620-mile-long fault that stretches from British Columbia to Northern California, and pressure is building daily.

Spectacular 3D seismic-reflection images of a subduction zone. ... This next one is a perspective block diagram beautifully showing both cross-sectional and map views of the accretionary wedge.

The Cascadia Subduction Zone just off the Pacific Coast of the US can trigger earthquakes greater than magnitude 8. For the first time, scientists have created a comprehensive map of its ...

Subduction zones are the most important sites of material exchange between the crust and mantle on Earth. They are also the locations where the largest deposits of strategic metals, such as copper, ...

A megasplay fault branches upward from the subduction zone, and in the event of "The Big One," would raise the seafloor, displacing a massive amount of water closer to the coast.
