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.
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 ...
Goulet said the USGS analysis suggests there is about a 5% chance that an earthquake greater than magnitude 6.0 could rupture in the area within the next week. “Following a 7, there could be ...
1979 Imperial Valley earthquake – magnitude 6.4 earthquake with an epicenter less than 1 km inside Mexico – significant damage and injuries on both sides of the border (60 in the US) 2010 Baja California earthquake (Mexico near S California) – magnitude 7.2 earthquake, 4 fatalities and 100 injuries, none in the United States
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 ...
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.
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 ...
