The vast quantity of volcanoes and earthquakes along the Pacific Ring of Fire exists largely thanks to the many subduction zones that lie along its path.

The 1980 eruption cycle made Mount St. Helens one of the most famous volcanoes in the Cascades. But it is far from the only volcano in the range.

SEATTLE — 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 ...

Scientists are sounding the alarm on a 'sleeping giant' off the coast of California, warning it could sink land in several states in just minutes.

Subduction is a feature of plate tectonics, so these widespread rocks show with certainty that plates were crashing into and sliding under one another.

ABSTRACT Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the ...

Some of the world’s largest earthquakes and tsunamis have originated from the Cascadia Subduction Zone, a 1,127-kilometer (700-mile) stretch that runs from northern California up to British ...
