District Type: Legislative Congressional. Liquefaction is the sudden loss of shear strength of a saturated sand or silt due to earthquake shaking. Seismic Soils & Liquefaction Risk B B-C C C-D Rock Very Dense Soil & Soft Rock Stiff Soil Soft Soil Requires Site-Specific Investigation Increasing Amplification of Ground Shaking D D-E E F Soil classification data provided by the Washington State Department of Natural Resources - Soil Classification Division of Geology & Earth Resources. In response to the Nisqually earthquake of 2001, the Survey was awarded a grant by FEMA and the Washington Emergency Management Division to develop two types of earthquake hazard maps for every county in the state—liquefaction susceptibility maps, which outline areas where water-saturated sandy soil loses strength during earthquake shaking, and NEHRP (National Earthquake Hazards Reduction Program) site class maps… Get directions, maps, and traffic for Washington. The shear strength is controlled by the degree of grain-to-grain contact (friction) in the sediment.
