King County and Seattle sit in one of the most seismically active regions of the continental US. The Seattle Fault runs directly beneath the city and is capable of a magnitude 7.0 earthquake. Mount Rainier — the most dangerous volcano in the US — looms 54 miles southeast, and a major eruption or lahar could send mudflows down river valleys into populated suburbs within hours.
