Where is the giant undersea earthquake zone known as the Cascadia Subduction Zone?
Quick Answer
The Cascadia Subduction Zone lies off the Pacific Northwest of North America. It stretches from northern California through Oregon and Washington to British Columbia.
The Full Story
The Cascadia Subduction Zone is offshore along the west coast of North America, where the Juan de Fuca Plate is descending beneath the North American Plate. It is capable of generating very large earthquakes and tsunamis. Geological evidence suggests it produced a magnitude 9-class event in 1700. Today, emergency planners in the region treat it as one of the continent’s major seismic hazards.
