Stephen Palmer, Washington State Department of Natural Resources, Division of Geology and Earth Resources Open File Report 2004-20 Version 2.0 liquefaction_susceptibility These data contain polygons that provide information regarding the relative liquefaction potential for Washington State. This feature class is part of a geodatabase that contains statewide ground response data for Washington State. Other feature classes are seismic_design_class_d, seismic_design_site_class, and seismic_site_class. Liquefaction is a natural phenomenon in which saturated, sandy soils lose their strength and behave as liquid. Liquefaction is a caused by severe ground shaking during earthquake events. Polygons are classified as having 'very low' to 'high' relative liquefaction susceptibility. Areas underlain by bedrock or peat are mapped separately as these earth materials are not liquefiable, although peat deposits may be subject to permanent ground deformation caused by earthquake shaking and require site-specific analysis under the International Building Code. Water and ice are also separately designated. Liquefaction susceptibility is assigned based on criteria described in: Palmer, Stephen P.; Magsino, Sammantha L.; Bilderback, Eric L.; Poelstra, James L.; Folger, Derek S.; Niggemann, Rebecca A., 2007, Liquefaction susceptibility and site class maps of Washington State, by county: Washington Division of Geology and Earth Resources Open File Report 2004-20, 78 plates, with 45 p. text.

This report more fully explains the scientific methods used in producing these data and can be found at http://www.dnr.wa.gov/ResearchScience/Topics/GeologyPublicationsLibrary/Pages/pub_ofr04-20.aspx. The Washington State Department of Natural Resources, Division of Geology and Earth Resources received grant funding through the Hazard Mitigation Grant Program (HMGP) following the Nisqually earthquake of February 2001 (FEMA-1361-DRWA). This grant required the Division of Geology and Earth Resources to develop statewide liquefaction susceptibility and NEHRP (National Earthquake Hazards Reduction Program) site class maps. Regional earthquake hazard maps such as these support hazard mitigation, emergency planning and response, planning of local zoning ordinances, and building code enforcement. The primary reason for producing this series of earthquake hazard maps is to support revisions to the State Hazard Mitigation Plan required in the implementation of final rules 44CFR201.4 and 44CFR201.6. These Federal code regulations require both state and local agencies to describe the location and extent of earthquake hazards that affect their jurisdictions. Additionally, these maps will serve a great variety of end-users that are crucial partners in earthquake hazard mitigation.

Olympia Washington 98504-7007 360-902-1450 360-902-1785 geology@dnr.wa.gov This map is based solely on surficial geology published at a scale of 1:100,000 by the Washington State Department of Natural Resources, Division of Geology and Earth Resources (Washington Division of Geology and Earth Resources staff, 2001) for most of the state. Detailed maps have been incorporated into the liquefaction susceptibility maps for portions of King, Pierce, and Thurston Counties. Additionally, a detailed liquefaction susceptibility map was developed for Clark County using 1:24,000-scale geologic mapping and based on the analysis of a large database of geotechnical borings and incorporation of a shallow groundwater model. Each polygon was assigned a liquefaction susceptibility code and then dissolved on that code. The assigned susceptibility is a result of a complex process that took into account the measure of physical characteristics of a soil deposit, such as grain and texture, compaction, and depth of groundwater, that determine the propensity of the soil to liquefy during earthquake shaking. For a detailed description of this process (both nontechnical and technical) see the sections titled "Development of Liquefaction Susceptibility and Site Class Maps for Washington State and "Liquefaction Susceptibility Map Methodology" in the document Liquefaction Susceptibility and Site Class Maps of Washington State, By County in the document ofr04-20.pdf located at the following site: http://www.dnr.wa.gov/ResearchScience/Topics/GeologyPublicationsLibrary/Pages/pub_ofr04-20.aspx Version History Version 2.0 (June, 2010): This dataset was migrated from a shapefile to a feature class within a geodatabase.Feature class names and attribute names were changed, and metadata for the entire dataset was updated. Version 1.0 (October, 2008) Original data in shapefile format. This map is meant only as a general guide to delineate areas prone to liquefaction. Because the data used in the liquefaction susceptibility assessment have been sub-divided on the basis of regional geologic mapping, this map cannot be used to determine the presence or absence of liquefiable soils beneath any specific locality. This determination requires a site-specific geotechnical investigation performed by a qualified practitioner. A factor affecting map accuracy is the placement of contacts on the original geological mapping. Accuracy of these geologic contacts is influenced by a number of factors that include: - determination of geologic units and criteria used during field mapping, - correct identification of the geologic units, - accurate location of geologic contacts that can be observed and mapped in the field, - uncertainty in mapping of gradational contacts, and - inference of contact locations where they cannot be observed and mapped. Quantification of this source of map inaccuracy is difficult, if not impossible. For the purpose of this study the location of geologic contacts have been accepted at face value from their original sources and used as the basis for delineating areas of different liquefaction susceptibility. This hazard map is not intended to replace a site-specific investigation needed to determine if a particular locality is underlain by liquefiable soils. Therefore, it is strongly recommended that users of this map consider some level of site-specific investigation commensurate with their concern with mitigating the impact of earthquake-induced liquefaction. All polygons close. No duplicate features exist in the theme. Arc-node and polygon topology is maintained by ESRI ArcGIS software and is error free with respect to that software.

There are attributes describing the liquefaction susceptility in terms of high, medium, and low levels, and special categories such as water, ice and peat. The liquefaction susceptibility rating identifies the relative liquefaction potential for approximately 34,000 polygons from the geologic map of Washington State. Igneous and metamorphic rock are assumed to have no liquefaction potential and are designated as "bedrock". Water and ice are so designated and peat, which requires site-specific analysis in the International Building Code, is also separately designated. All other polygons are classified as having very low- to- high susceptibility rating, as described in Open-File Report 2004-20. Palmer, S. P.; Magsino, S. L.; Bilderback, E. L.; Poelstra, J.
