Just off the coast of the Pacific Northwest is the Cascadia Subduction Zone, a complex collection of earthquake faults ...

When an earthquake rips along the Cascadia Subduction Zone fault, much of the U.S. Pacific Northwest fault zone could trigger a catastrophic 5-minute quake, new research warns Skip to main content ...

The last time this Cascadia subduction zone shook off a major earthquake was in 1700. Since then, the coastline has been rising by 0.04 to 0.12 inch (1 to 3 millimeters) a year, slightly outpacing ...

But they can’t say exactly when the Pacific Northwest’s “Big One” could strike. The last great earthquake along the Cascadia Subduction Zone occurred in January 1700, and big events are ...
