KLEBER, Emily, BOWMAN, Steve, CASTLETON, Jessica J., HISCOCK, Adam, ERICKSON, Ben and BEUKELMAN, Gregg S., Utah Geological Survey, Geologic Hazards Program, 1594 W North Temple, Salt Lake City, UT 84116,

The Wasatch Front is home to ~85% of Utah’s population, spectacular geology, and a host of geologic hazards. The Utah Geological Survey (UGS) has developed several web-based systems to collect and deliver pertinent geologic hazards data and information for use by the public, local governments, and others. The UGS GeoData Archive System contains over 17,000 resources including maps, field photographs, geotechnical reports, reconnaissance notes, and other published and unpublished items that are either approximately located or geolocated, text-searchable, and accessible online at Resources are from the extensive UGS holdings, along with those provided by local governments, consultants, and state and federal agencies. The Utah Aerial Imagery Collection ( contains over 95,000 aerial images from 1935 to present. The Utah Quaternary Fault and Fold Database ( contains the most recent Quaternary fault data and mapping available for Utah in an easily accessible web-map format. The Utah Landslide Inventory project locates and classifies landslides based on movement activity, source lithology, and boundary-mapping confidence. All mentioned resources are integral to the UGS Geologic Hazards Mapping Initiative which is focused on mapping geologic hazards in urban areas along the Wasatch Front and around the state. Limited exposure and accessibility in urban areas necessitates the use of data from a wide variety of sources to assess hazards such as landslides, surface fault rupture, liquefaction, problem soils, and radon. The collection and dissemination of these resources help the UGS fulfill its mission to provide timely scientific information about Utah's geologic environment, resources, and hazards. These resources can be directly used to reduce the risk from geologic hazards through awareness, implementing ordinances, and mitigation measures.
