PACIFIC NORTHWEST EARTHQUAKE - Magnitude 6.8 February 28, 2001 At 10:54 a.m. on February 28, 2001, a magnitude 6.8 earthquake shook the Pacific Northwest. Fifteen minutes after the earthquake, Shannon & Wilson dispatched a team of geotechnical earthquake engineers and geologists to investigate the geotechnical aspects of the event. The team initially focused on sites that had shown historical evidence of ground failure during 1949 (magnitude 7.1) and 1965 (magnitude 6.5) events. Most of the damage observed was located in Olympia and Tumwater and in artificial fill areas in and around Seattle. No liquefaction evidence was found in Puyallup where significant liquefaction had occurred in previous earthquake events. Pictures from Shannon and Wilson Website: http://www.shannonwilson.com/
