GEOLOGIC HAZARDS

Hazard Maps

Geologic hazard maps generally show areas that may be subject to the effects of earthquakes, landslides, debris flows, rock falls, poor soil conditions, radon, or floods.  The main purpose of geologic hazards maps is to identify where geologic hazards may be present and where additional evaluations are needed to assess hazards and recommend mitigation measures prior to development. This list of primarily UGS maps is not comprehensive for each region. Additional geologic-hazard publications are available at Geologic Hazard PublicationsPaleoseismology of Utah, New Maps and Publications, and the UGS Library.
