Scientists say that the Cascadia subduction zone off the coast of the Pacific Northwest has the potential to spark a magnitude-9.0+ earthquake, plus a subsequent tsunami. That scenario last ...
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.
[7] [4] [5] Seafloor core evidence indicates that there have been forty-one subduction zone earthquakes on the Cascadia subduction zone in the past 10,000 years, suggesting a general average earthquake recurrence interval of only 243 years. [2] Of these 41, nineteen have produced a "full margin rupture", wherein the entire fault opens up. [7]
Jun. 15—If humans could see the future, the West Coast would likely be spending every moment from now until its arrival preparing for the impending 9.0 Cascadia Subduction Zone earthquake. Off ...
[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 ...
The 2015 Uniform California Earthquake Rupture Forecast, Version 3, or UCERF3, is the latest official earthquake rupture forecast (ERF) for the state of California, superseding UCERF2. It provides authoritative estimates of the likelihood and severity of potentially damaging earthquake ruptures in the long- and near-term.
Nov. 15—OLYMPIA — The big one. The 9.0 magnitude Cascadia earthquake that experts say will change the West Coast forever. No one knows when, but scientists are pretty certain it will hit.
The 1700 Cascadia earthquake occurred along the Cascadia subduction zone on January 26, 1700, with an estimated moment magnitude of 8.7–9.2. The megathrust earthquake involved the Juan de Fuca plate from mid-Vancouver Island, south along the Pacific Northwest coast as far as northern California. The plate slipped an average of 20 meters (66 ...
