The Aleutian Trench, of the southern coast of Alaska and the Aleutian Islands, where the North American plate overrides the Pacific plate, has generated many major earthquakes throughout history, several of which generated Pacific-wide tsunamis, [22] including the 1964 Alaska earthquake; at magnitude 9.1–9.2, it remains the largest recorded ...
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.
A paleoseismic investigation using Lidar revealed that more than 16 feet (5 m) of slip has accumulated since the 1857 event on the southern SAF, which borders the Mojave Desert to the north and east of the Greater Los Angeles Area. Near the Transverse Ranges, reverse and thrust faults have produced damaging earthquakes in Santa Barbara and the ...
An earthquake ruptured off California on Thursday morning, briefly triggering a tsunami warning for the coast of Northern California and southern Oregon. 7.0 earthquake in Northern California ...
Having half a dozen earthquakes with a magnitude 2.5 or greater strike in a single week is not a common occurrence in Southern California.

A major earthquake struck near California's coast on Thursday, and aftershocks are still ongoing. The 7.0-magnitude earthquake struck at about 10:44 a.m. Pacific Time.
The 2021 Antelope Valley earthquake occurred in a rural area near the California–Nevada border. Due to the remoteness of the area, there were few sensor stations near the earthquake and this resulted in the M W 6.0 earthquake incorrectly being split into "phantom quakes" by the system – a M W 4.8 near Lee Vining , M W 4.8 near Stockton ...
