The 1993 Scotts Mills earthquake, also known as the "Spring break quake", occurred in the U.S. state of Oregon on March 25 at 5:34 AM Pacific Standard Time. With a moment magnitude of 5.6 and a maximum perceived intensity of VII ( Very strong ) on the Mercalli intensity scale , it was the largest earthquake in the Pacific Northwest since the ...
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 ...
Logo of the ANSS. The Advanced National Seismic System (ANSS) is a collaboration of the United States Geological Survey (USGS) and regional, state, and academic partners that collects and analyzes data on significant earthquakes to provide near real-time (generally within 10 to 30 minutes [1]) information to emergency responders and officials, the news media, and the public.

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 ...
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.
Organized by the Oregon Department of Emergency Management, the drill promotes earthquake preparedness. At the designated time, participants "drop, cover, and hold on" for at least one minute.
