The Oregon Department of Emergency Management estimates shaking would last 5–7 minutes along the coast, with strength and intensity decreasing further from the epicenter. [1] It is a very long, sloping subduction zone where the Explorer , Juan de Fuca , and Gorda plates move to the east and slide below the much larger mostly continental North ...
1834 Java earthquake (M 7.0) Brothers Fault Zone: Oregon, United States: Bulnay Fault: 370: Mongolia: Sinistral: Active: 1905 Bolnai (M8.3) Calaveras Fault: 120: San Francisco Bay Area, California, United States: Dextral: Active: 1911 Morgan Hill (M6.5), 1984 Morgan Hill (M6.2) Cascadia megathrust: 1000: West coast of United States – Oregon ...
The Blanco fracture zone between the Gorda Ridge and the Juan de Fuca Ridge. The Blanco fracture zone or Blanco transform fault zone (BTFZ) is a right lateral transform fault zone, which runs northwest off the coast of Oregon in the Pacific Northwest of the United States, extending from the Gorda Ridge in the south to the Juan de Fuca Ridge in the north.
A fault off the Pacific coast could devastate Washington, Oregon and Northern California with a major earthquake and tsunami. Researchers mapped it comprehensively for the first time.
An earthquake ruptured off California on Thursday morning, briefly triggering a tsunami warning for the coast of Northern California and southern Oregon. The earthquake, a magnitude-7.0 temblor ...
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen ...
A map of the Juan de Fuca plate with noted seismic incidents, including the 2001 Nisqually earthquake. The Juan de Fuca plate is bounded on the south by the Blanco fracture zone (running northwest off the coast of Oregon), on the north by the Nootka Fault (running southwest off Nootka Island, near Vancouver Island, British Columbia) and along the west by the Pacific plate (which covers most of ...
A hole in a 600-mile-long fault line has been discovered at the bottom of the Pacific ocean - and it could be the trigger of a magnitude-9 earthquake on the US coast. Just outside of Oregon ...
