[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 University of Oregon's earthquake research center will bring together 16 institutions to research earthquakes and the Cascadia subduction zone.
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.
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 ...
The last known great earthquake in the northwest was the 1700 Cascadia earthquake, 324 years ago. Geological evidence indicates that great earthquakes (> magnitude 8.0) may have occurred sporadically at least seven times in the last 3,500 years, suggesting a return time of about 500 years.
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).
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.
A major achievement of UCERF3 is use of a new methodology that can model multifault ruptures such as have been observed in recent earthquakes. [5] This allows seismicity to be distributed in a more realistic manner, which has corrected a problem with prior studies that overpredicted earthquakes of moderate size (between magnitude 6.5 and 7.0).
