Plate Tectonic Setting off the Coast of Washington
Detailed Description
Map showing the plate tectonic setting off the coast of Washington. The Juan de Fuca plate is slowly moving toward and subducting underneath the North American plate. The red line with triangles represents the Cascadia Subduction Zone, where one plate subducts under the other and where it can generate an earthquake and trigger a tsunami. Credit: Eric Geist, USGS
