Known as the Cascadia subduction zone, it runs for seven hundred miles off the coast of the Pacific Northwest, beginning near Cape Mendocino, California, continuing along Oregon and Washington, and terminating around Vancouver Island, Canada.
Could the Puget Sound have a tsunami?
New tsunami hazard maps published by the Washington Geological Survey and the Washington State Department of Natural Resources (DNR) show that a large earthquake on the Cascadia subduction zone (CSZ) off the Washington coast could cause a tsunami that will not only reach the Puget Sound and Hood Canal, but will leave …
Where is the Cascadia inundation zone?
The Cascadia Subduction Zone (CSZ) is a 1,000 kilometer fault where the Juan de Fuca and North American plates meet. Located off the Pacific Northwest coast, this plate runs from central Vancouver Island, B.C. to northern California.
