Minor earthquake shakes areas south of Issaquah
September 27, 2011
Seismologists recorded a magnitude-3.2 earthquake south of Issaquah last week, but the minor tremor did not cause any damage or injuries.
University of Washington seismologists said the minor earthquake occurred at 1:22 p.m. Sept. 22. Scientists pegged the earthquake’s epicenter near Lake Desire in rural King County, about eight miles southwest of downtown Issaquah.
King County Sheriff’s Office deputies did not respond to any calls related to earthquake-related problems or damage, spokesman Sgt. John Urquhart said.
Seismologists at the Pacific Northwest Seismic Network, based at the UW, said the temblor occurred about 15 miles beneath the surface.
September is National Preparedness Month, and the state Emergency Management Division conducted a statewide drop, cover and hold earthquake drill the day before the Lake Desire temblor.
The seismic activity came a month after seismologists recorded a minor earthquake beneath Mirrormont on Tiger Mountain. The magnitude-2.8 earthquake occurred just before 1 a.m. Aug. 18, about a mile beneath the surface.
Scientists said such small earthquakes occur often, and do not indicate a looming, larger earthquake.
