Human-caused quakes a big problem, but not in Utah yet

fox13now.com

While geologists warn that human-caused earthquakes have become a real problem in some places, the greatest risk in Utah is still a natural quake along the Wasatch Front.

GEOLOGIC MAP OF THE CHARLESTON QUADRANGLE, WASATCH COUNTY, UTAH
Robert F. Biek and Mike Lowe

The Charleston quadrangle lies on the south edge of a structural and topographic saddle between the Wasatch Range and Uinta Mountains.  The quadrangle includes the southern part of Heber City and Heber Valley and the northern half of Round Valley, as well as parts of Deer Creek Reservoir and Wasatch Mountain State Park.  The quadrangle also straddles the north edge of the Charleston-Nebo thrust plate, and thus includes three distinct groups of rocks: (1) a nearly complete section of Pennsylvanian rocks of the Oquirrh Formation that comprises the Charleston thrust plate; (2) underlying, southeast-dipping Jurassic and Triassic strata below the Charleston thrust; and (3) Upper Proterozoic, Cambrian, and Mississippian strata that are exposed in a structurally complicated zone between the Charleston thrust and Deer Creek detachment faults.
A variety of late Tertiary and Quaternary deposits record the evolution of the present landscape.

This geologic map and report provide basic geologic information necessary to further evaluate geologic hazards and resources in the area, and to gain an understanding of the geology upon which this landscape developed.

OPEN-FILE REPORT 548

OFR-548COMPILATION OF 1970s WOODWARD-LUNDGREN & ASSOCIATES WASATCH FAULT INVESTIGATION REPORTS AND OBLIQUE AERIAL PHOTOGRAPHY, WASATCH FRONT AND CACHE VALLEY, UTAH AND IDAHO
Steve D. Bowman, Keith Beisner, and Corey Unger

This nine DVD set contains a descriptive 3-page report and digital files created from the Wasatch fault investigation project performed for the Utah Geological and Mineralogical Survey (now the Utah Geological Survey) and the U.S. Geological Survey by Woodward-Lundgren & Associates.  The project was performed to identify surface fault rupture hazard areas along the Wasatch fault and in Cache Valley.  This compilation contains digital scans of the three separate Wasatch fault reports, 47 fault maps, and 1326 oblique aerial photographs (frames).  The digital files include aerial photograph scans in TIFF format, fault maps in TIFF and Adobe PDF formats, and index maps in Google Earth KMZ, GIS shapefile and Adobe PDF formats.  Specialized software (not included) is required to utilize the Google Earth and GIS files, and can be downloaded from the Internet.

This compilation will be useful for professionals involved with paleoseismology investigations; geologic, geotechnical, and environmental assessment and investigation projects; land-use planning and management; government agencies; and the general public and others as an historical archive.  Oblique aerial photography was used to highlight certain topographic features, such as fault scarps and traces, for mapping purposes.
