2022年9月27日 · Map showing Quaternary faults in the western U.S. and Pacific Ocean. Note that most faults that can affect residents are either onshore or just offshore. The various colors and line types indicate different ages of the most recent earthquakes on the fault and how well the location of the fault is constrained.

WHAT ARE FAULTS AND EARTHQUAKES? This map shows areas of seismic risk from high (red) to low (grayish-green). The map is from a 2007 report (click here to download) on seismic design categories in Washington. The map also shows potentially active faults from a separate 2014 report (click here to download).

Interactive fault map and comprehensive geologically based information on known or suspected active faults and folds in the United States. Also, generalized fault data used in the hazard maps.

Seattle Fault Peak Ground Acceleration; 7.2-Magnitude Scenario Shake Map Magnitude: 7.2 Depth: 10.0km Epicenter: N47.60 W122.57 Appx. 10mi W of Seattle, WA The Seattle fault is a zone of thrust or reverse faults that strikes through downtown Seattle in the densely populated Puget Lowland of western Washington. Analysis of seismic profiles extending

A new analysis of the Seattle area’s risk during a major earthquake has found new locations at higher potential for violent shaking. Highlighted in dark red, the Interbay area between Magnolia and Queen Anne along with northern Montlake and the University Village area are now considered at high risk for strong ground shaking in a quake.

Inundation maps show areas at risk of inundation by tsunamis that are generated from large earthquakes. These maps are based on model results from hypothetical earthquake scenarios on the Cascadia subduction zone, Seattle Fault, or Tacoma fault.

Puget Sound and Seattle Earthquake Fault Map. Southern Whidbey Island faults and Seattle fault sits over the heavily populated Seattle metropolitan area.

The Seattle Fault is a zone of multiple shallow east–west thrust faults that cross the Puget Sound Lowland and through Seattle (in the U.S. state of Washington) in the vicinity of Interstate Highway 90.

Scientists believe the cause of that big earthquake was a fault that lies right beneath our feet. The Seattle fault bisects the city west to east, from Alki Point in West Seattle, through...
