The Cascadia subduction zone is a 1,000 km (620 mi) long dipping fault that stretches from Northern Vancouver Island to Cape Mendocino in northern California. It separates the Juan de Fuca and North America plates. New Juan de Fuca plate is created offshore along the Juan de Fuca Ridge. [8] [9]
Over the past century, scientists have only observed five magnitude-9.0 or higher earthquakes — all megathrust temblors like the one predicted for the Cascadia Subduction Zone.
Back in North America, in 1700, a 9.0 earthquake and monster tsunami rocked the Cascadia region, an area that stretches along what would become Western Washington, Oregon and northern California ...
The University of Oregon's earthquake research center will bring together 16 institutions to research earthquakes and the Cascadia subduction zone. ... 2023 at 8:00 AM. ... Depending on location ...
Northern California has an estimated 12% chance over the same 30 years of an M ≥ 8 megathrust earthquake on the Cascadia subduction zone. [6] UCERF has also prepared "participation probability maps" [7] of the chance that any area will experience an earthquake above a certain magnitude from any source in the next 30 years (see figure).
Map showing the amount of advance warning time that might be available from ShakeAlert for several plausible future earthquake scenarios. [1]Initially the system has been developed to monitor and alert the West Coast of the United States, an area with significant seismic risk due to the San Andreas fault zone and the Cascadia subduction zone.
Diego Melgar Moctezuma, associate professor of earth sciences at the University of Oregon and the director of the new Cascadia Region Earthquake Science Center, poses in his office on Oct. 18, 2023.
[1] [2] The stated mission of the center [3] is to (i) carry out basic and applied science research on earthquake hazards at the Cascadia Subduction Zone, (ii) promote access to careers in the geosciences, especially amongst minoritized individuals, and (iii) form partnerships between researchers and organizations in charge of response and ...
