[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 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 ...
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.
On December 5, 2024, a M w 7.0 earthquake struck off the coast of Humboldt County, California, at 10:44 a.m. PST. It was felt in the state's northern regions and in the Central Valley. [2] The earthquake prompted the National Weather Service to issue a tsunami warning which was canceled soon after.
The University of Oregon's earthquake research center will bring together 16 institutions to research earthquakes and the Cascadia subduction zone.
Three types of earthquake are observed in the area: rare megathrust events, such as the 1700 Cascadia earthquake, shallow events within the North American plate and deeper intraslab events within the Juan de Fuca plate as it sinks into the mantle. The third type of earthquake is the one that has led to the greatest amount of damage.
Cascadia subduction zone, Vancouver Island. In 1996, a team of researchers linked the orphaned 1700 tsunami in Japan with a magnitude 9 earthquake and tsunami in North America in a Trans-Pacific reunion. [7]: 94–95 [8] [9] Scientists "dated the earthquake to the evening of January 26, 1700" and approximated its size as magnitude 9.
