Another notable intraslab earthquake in the Puget Sound region was the magnitude 6.8 2001 Nisqually earthquake. Intraslab earthquakes in Cascadia occur in areas where the subducting plate has high curvature. [13] Much of the seismicity that occurs off the coast of northern California is due to intraplate deformation within the Gorda plate.
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 ...
Damaging earthquakes are well known in the Pacific Northwest, including several larger than magnitude 7, most notably the M9 1700 Cascadia earthquake and the M7.0–7.3 earthquake in about 900AD on the Seattle Fault. The M6.5 1965 Puget Sound earthquake shook the Seattle, Washington, area, causing substantial damage and seven deaths. This event ...

A sizable 6.1 magnitude earthquake struck near the Oregon Coast Wednesday afternoon. The National Weather Service (NWS) first announced the earthquake on social media, saying it struck at around 1 ...
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.
An earthquake shook off the Oregon coast Wednesday afternoon. The earthquake struck in the Pacific Ocean, more than 170 miles west of Bandon, Oregon at 1:15 p.m. local time, according to the U.S ...
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.
