A new study published in Science Advances has revealed the first detailed images of a newly developing subduction zone off ...

New Cascadia Subduction Zone research suggests the tsunami risk for some coastal communities in the Pacific Northwest may not be quite as acute as originally thought.

One such fault, the Cascadia Subduction Zone off the U.S. Pacific Northwest, has not shown signs of slow slip at its tsunami-generating end—raising concerns that it may be more tightly locked ...

A study in Geology presents evidence that subduction can spread like a contagion, jumping from one oceanic plate to another — a hypothesis previously difficult to prove.

Tectonic Plates Can ‘Infect’ One Another with Earth-Shaking Subduction Zones Evidence from Earth’s deep past suggests dramatic subduction zones can spread like a contagion ...

Landslides, earthquakes, and subduction faults could generate 1,000-foot mega-tsunamis, wiping coastal communities off the map.

California's continuous temblor risk coincides with a huge earthquake brewing along the Cascadia Subduction Zone off the coast of the Pacific Northwest.

There is a sleeping giant off the coast of the Pacific Northwest that could cause chaos to North America when it eventually wakes up. Known as the Cascadia Subduction Zone, this 1,130-kilometer ...

The Cascadia Subduction Zone, stretching from northern California to British Columbia, is one of the most dangerous seismic hotspots in North America, capable of producing a massive 9.0 magnitude ...

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.
