The Impacts of the Cascadia Subduction Zone Earthquake on. Large megathrust earthquakes occur on average every 550 years on the northern Cascadia subduction zone, where the Juan de Fuca tectonic plate subducts underneath the North American plate off the coast of Washington State. Scientists had thought that major earthquakes were likely to occur only offshore, but a new analysis by Chapman and Melbourne (2009) shows that a giant earthquake could, In addition to the offshore Cascadia Subduction Zone, the Seattle Fault runs underneath the city of Seattle (Marked by pin) and could rupture in a M=7+ earthquake. All of these factors result in Seattle having a Temblor Hazard Rank of 21..

  • A megathrust earthquake is a very large earthquake that occurs in a subduction zone, a region where one of the earth's tectonic plates is thrust under another. The Cascadia subduction zone is located off the west coast of North America. From mid Vancouver Island to northern California the Juan de Fuca Plate is subducting beneath the North American Plate. The two plates are continually moving The oceanic lithosphere entering the Cascadia subduction zone in all segments is extremely young, less than 10 Ma. Of the other six zones around the Pacific where young (< 20 Ma) lithosphere is being subducted, five have had major thrust earthquakes (megathrust events) on the subduction interface in historic time.
