The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

To investigate this puzzle, a team lead by Dr. David Hernández Uribe and Professor Tatsuki Tsujimori from the Department of Earth and Environmental Sciences at the University of Illinois Chicago and ...

The research, recently published in the prestigious journal Science Advances, produced the most detailed picture researchers have yet of the Cascadia Subduction Zone, an area spanning more than ...

The Pacific Ring of Fire is a zone of high seismic and volcanic activity. It is responsible for most of the world's ...

Huang says finding active areas of subduction zones where earthquakes tend to occur, and examining why earthquakes occur in these areas, can help researchers devise better earthquake warning systems.

Researchers recently discovered a huge chain of extinct volcanoes buried deep below South China that formed when two tectonic ...

The tsunami advisories from Tuesday are a good reminder for people in Western Washington to know their plan of when to ...

The model predicts that the extended subduction zone will form a new Atlantic subduction system – the so-called 'Ring of Fire', named after the Pacific Ocean version that already exists.

The Pacific Northwest is at risk for a mega-earthquake because of the Cascadia Subduction Zone. The region is primed for powerful quakes, with a particularly strong one called the Big One ...
