Description: This database contains maps of NEHRP seismic site class and liquefaction susceptibility for the portion of the Wood River containing the cities of Sun Valley, Ketchum, Hailey, and Bellevue. The NEHRP seismic site class map is based upon measurements at 51 sites of average shear wave velocity within 30 m (100 ft) of the surface (Vs30). These measurements were extrapolated throughout the map area using a surficial geologic map. The data used to construct the maps are provided in ESRI ArcMAP format version 10.1, and as Microsoft Excel spreadsheets of the Vs30 depth profiles. An Appendix provides details on how the site class maps were constructed. Liquefaction susceptibility was constructed using a model of depth to the regional water table and with an age-time-environment classification of surficial geologic units. Both maps contain further explanatory text.
