But the Seattle and Tacoma faults are probably the most serious earthquake threat to the populous Seattle–Tacoma area. A 2002 study of bridge vulnerability estimated that a magnitude 7 earthquake on the Seattle Fault would damage approximately 80 bridges in the Seattle–Tacoma area, [ 30 ] whereas a magnitude 9 subduction event would damage ...
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 ...
Note: The inclusion criteria for adding events are based on WikiProject Earthquakes' notability guideline that was developed for stand-alone articles. The principles described also apply to lists. In summary, only damaging, injurious, or deadly events should be recorded.

Seismotectonics is the study of the relationship between the earthquakes, active tectonics and individual faults of a region. It seeks to understand which faults are responsible for seismic activity in an area by analysing a combination of regional tectonics, recent instrumentally recorded events, accounts of historical earthquakes and geomorphological evidence.
Scientists knew it wasn’t an earthquake, so they labeled the event a USO (unidentified seismic object) and began searching for a cause. The investigation (involving 68 scientists, 40 ...
Taylor Swift’s recent Eras Tour concerts had fans in Seattle, Washington shook, literally. Swifties have been passionately singing and dancing along during the 33-year-old singer’s U.S ...
(Excerpt from DGER Geological Map GM-52.) 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 ...
