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 ...

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.
The quake, which had a center near Ferrelview and the Kansas City International Airport, was reported around 1:45 p.m. March 15. Magnitude 3.5 earthquake near KCI was caused by mine collapse: USGS ...
The earthquake struck about 1:45 p.m. just over a half mile northeast of the village, near where Interstates 29 and 435 intersect east of Kansas City International Airport, according to the USGS.

One study of seismic vulnerability of bridges in the Seattle – Tacoma area [4] estimated that an M 7 earthquake on the Seattle or Tacoma faults would cause nearly as much damage as a M 9 subduction earthquake. Because the Seattle and Tacoma faults run directly under the biggest concentration of population and development in the region, more ...
