How deep is the Cascadia fault?
The Cascadia subduction zone is a 960 km (600 mi) fault at a convergent plate boundary, about 110–160 km (70–100 mi) off the Pacific coast, that stretches from northern Vancouver Island in Canada to Northern California in the United States. It is capable of producing 9.0+ magnitude earthquakes and tsunamis that could reach 30 m (98 ft).
Oct 23, 2017 · A UW research project explores how a magnitude-9.0 earthquake on the Cascadia subduction zone could affect Seattle and other coastal areas. The results show that the intensity of shaking can vary by a factor of 10 depending on the epicenter, the rupture extent and the sticky points of the fault.
Jul 13, 2015 · Just north of the San Andreas, however, lies another fault line. Known as the Cascadia subduction zone, it runs for seven hundred miles off the coast of the Pacific Northwest, beginning near...
Aug 5, 2018 · The Cascadia Fault is a subduction zone where two tectonic plates collide, capable of producing massive earthquakes. Scientists have found that the fault is more active in the north and south, where the mantle is hotter and slower, than in the central part, where it is cooler and faster.
Learn about the 1,000 km long fault that separates the Juan de Fuca and North America plates and produces great megathrust earthquakes every 400 to 600 years. Find out the history, science and hazards of the Cascadia Subduction Zone from PNW earthquake sources.
Aug 14, 2020 · Topo-bathymetric map of the Cascadia subduction zone. Cascadia megathrust fault (white line); approximate shelf break along 200-m isobath (yellow line); MTJ, Mendocino triple junction.
Learn about the geologic features, hazards, and research of the Cascadia subduction zone, where the Juan de Fuca plate dives beneath the North American plate. Find data, maps, animations, and publications on earthquakes, tsunamis, volcanoes, and more.
