The Seattle Fault was first identified in 1965 [108] but not documented as an active fault until 1992 with a set of five articles establishing that about 1100 years ago (AD 900–930) an earthquake of magnitude 7+ uplifted Restoration Point and Alki Point, dropped West Point (the three white triangles in the Seattle Basin on the map), caused ...
Over the past century, scientists have only observed five magnitude-9.0 or higher earthquakes — all megathrust temblors like the one predicted for the Cascadia Subduction Zone.
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 ...
Multiple earthquakes of magnitude 3.0 and higher struck off the west coast in the Pacific Ocean in the early morning hours of Friday, Oct. 18., according to the Pacific Northwest Seismic Center.
There have been just under 40 earthquakes of magnitude 6.0 or larger in the past century within 150 miles of Thursday’s earthquake, which was the most powerful to rattle the state since a 7.1 ...
The 1949 Olympia earthquake was a damaging magnitude 6.7 intraslab earthquake that occurred at 52 km depth and caused eight deaths. 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]
