<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Utah Geological Survey Quaternary Fault and Fold Database and Map of Utah is a compilation of existing information on faults and fault-related folds considered to be potential earthquake sources (i.e., “active” faults and folds). The faults and folds contained in the database are those considered to have been sources of large earthquakes (about magnitude 6.5 or greater) during the Quaternary Period (past 2.6 million years); these geologic structures are the most likely sources of large earthquakes in the future. The database is intended to be a comprehensive source of the most current information available for characterizing active faults and folds in Utah for seismic-hazard analysis. This version of the database incorporates fault data from geologic maps and other documents formally published through 2020, along with several additional faults. More information on faults and earthquake hazards in Utah is available at http://geology.utah.gov/hazards/earthquakes-faults/utah-faults.</SPAN></P><P><SPAN>The database was compiled and attributed using ESRI ArcGIS geographic information system software. In general, the database attribute conventions follow those of the Quaternary Fault and Fold Database of the United States maintained by the U.S. Geological Survey (USGS).</SPAN></P></DIV></DIV></DIV>
To show the mapped Quaternary faults and folds in the State of Utah, April, 2021 release.

FaultClass
Class A – Tectonic faults with evidence of Quaternary deformation.
Class B – Faults with evidence of Quaternary deformation, but where the fault may not extend deep enough to be a potential earthquake source, or the currently available evidence is limited.
Class C - Geologic evidence is insufficient to demonstrate (1) the existence of tectonic fault, or (2) Quaternary slip or deformation associated with the feature.

FaultNum
Number assigned to the structure, within the range specified by the USGS for each state. Fault section numbers include a structure number and an alpha-numeric (a, b, etc.) section designation; for example, the Salt Lake City segment of the Wasatch fault zone is identified as number 2351f. For structures that cross the state border, numbers may be taken from the adjacent state.
