Seven of its volcanoes have erupted since the start of the 18th century. Our research cruise is happening along the continental margin behind the subduction zone itself. Close. **Our intentions are aimed towards a fairer, more transparent world and a better future for everyone. ** New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge.. A devastating earthquake and subsequent tsunami, dubbed "the really big one" in a New Yorker article of the same name, is destined to strike a fault … The Cascadia Subduction Zone is where the oceanic Juan de Fuca plate is diving underneath the North American plate. The Cascadia Subduction Zone, located in the U.S. Pacific Northwest and southwestern British Columbia, has hosted magnitude ≥8.0 megathrust earthquakes in the geologic past, a future earthquake is imminent, and the potential impacts could cripple the region. The undersea Cascadia thrust fault ruptured along a 1000 km length, from mid Vancouver Island to northern California in a great earthquake, producing tremendous shaking and a huge tsunami that swept across the Pacific. Abstract Southwest British Columbia has the potential to experience large‐magnitude earthquakes generated by the Cascadia Subduction Zone (CSZ). John F. Cassidy, Robert M. Ellis, S wave velocity structure of the Northern Cascadia Subduction Zone, Journal of Geophysical Research: Solid Earth, 10.1029/92JB02696, … https://www.newyorker.com/magazine/2015/07/20/the-really-big-one, https://pnsn.org/outreach/earthquakesources/csz. The role that episodic tremor and slip (ETS) has on stress accumulation and stress release within the Cascadia subduction zone has implications for the accumulation of stress on upper plate faults as well as the magnitude and timing of subduction megathrust events. I found this... http://www.zazzle.com/run+like+hell+gifts. Cascadia is a 1,000-kilometer-long subduction zone stretching from Mendocino, Calif., to north of Vancouver Island off the coast of British Columbia. The CSZ is different than most subduction zones in that it is "locked." Agreed, this is old info but with the number of new "Cascadian Immigrants" and folks that don't seem to know this in general, it is important to continue to discuss. Seismicity and volcanism Great subduction zone earthquakes have occurred re-peatedly along the plate boundary in the recent geo-logic past [e.g., Atwater and Hemphill-Haley, 1997], but Reminder: Cascadia Subduction Zone in the Pacific Northwest "Our operating assumption is that everything west of Interstate 5 will be toast." Evidence has been obtained for the accumulation of elastic strain across the northern Cascadia subduction zone that may be released in a future very large subduction thrust earthquake. Posted by. An earthquake on the Seattle Fault poses the greatest direct risk to the city of Seattle. It is a very long, sloping subduction zone that separates the Explorer, Juan de Fuca, and Gorda plates, on the one hand, and the North American Plate, on the other. Some might say it's 4.5 billion years in the making. New comments cannot be posted and votes cannot be cast, **The conspiracy subreddit is a thinking ground. The Cascadia subduction zone is a region where two tectonic plates are colliding. “Faults tend to be pretty good at this. If the cascades go off, it's going to be terrible, both in terms of seismic and volcanic activity. The connection not only confirmed that the Cascadia Subduction Zone is active; it placed it among the most powerful subduction zones in the world. Archived. Reddit; Wechat; Abstract. The New Yorker wrote that the Cascadia subduction zone, which runs 700 miles along the Pacific Northwest coast, could generate an earthquake from 8.0 and 8.6 magnitude if the southern portion of the zone gives way.
