Technical Presentations. The following presentations were made on current paleoseismic research and related activities in Utah: • Paleoseismicity of the Salt Lake City segment―Results from the Penrose Drive trench investigation; Chris DuRoss, UGS • Update on fault trenching at the Baileys Lake site, West Valley fault zone; Mike Hylland, UGS • Searching for evidence of seismic events in lacustrine sediments in Utah Lake; Quincy Nickens, Brigham Young University • Hurricane Cliffs hydropower and Lake Powell pipeline preliminary Quaternary fault investigation; Dean Ostenaa, Fugro, Inc. • Blue Castle licensing project; Dean Ostenaa, Fugro, Inc. • Summary of preliminary investigations of the Paunsaugunt fault, Utah; Bob Kirkham, RJH Consultants (no Power Point, hard copy handout) • Utah Geological Survey Nephi segment trenching project, June 2012: Chris DuRoss, UGS • Characterizing the central Wasatch fault zone for the Working Group on Utah Earthquake Probabilities; Chris DuRoss, UGS • Comparison of moment rates from GPS observations and late Quaternary earthquakes on the Wasatch fault, Utah; Christine Puskas, UNAVCO • The Working Group on Utah Earthquake Probabilities (WGUEP)―Background, goals, and progress; Ivan Wong, URS Corporation • Basin and Range Province Earthquake Working Group II; Bill Lund, UGS • East Cache fault zone study; discussion leader Bill Lund, UGS A long-standing question exists regarding the status of the National Earthquake Hazard Reduction Program (NEHRP)-funded investigation titled Earthquake Timing on the Southern Segment of the East Cache Fault Zone, Utah by Utah State University (USU). Originally approved by NEHRP in 2007 as a one-year investigation, results of the study are not yet available to the public. Cache Valley is one of Utah’s most populous regions off the Wasatch Front, and as such, the results of the USU investigation are important to seismic-hazard reduction for that area.

In 2005, the UQFPWG recommended that 20 Quaternary faults/fault segments in Utah be investigated to “adequately characterize Utah’s earthquake hazard to a minimally acceptable level” (Lund, 2005). Since then, the Working Group has added an additional 11 faults/fault segments to the list: Chris DuRossfive in 2007, one in 2009, one in 2010, and four in 2011 (see table 1 below). No new faults were added to the list in 2013. The UQFPWG conducts an annual review of progress made toward investigating the faults/fault segments on their priority list. Based on that review, the Working Group establishes a short list of the highest priority faults/fault segments for future study. The list of highest priority faults/segments is published on the UGS • Characterizing web site, which is then referenced by the USGS in their annual NEHRP request for proposals. The Working Group’s highest priority list for 2013 includes: (1) Acquire new paleoseismic information for the five central segments of the Wasatch fault zone for to address data gaps – e.g., (a) the Working Group on Utah Earthquake Probabilities; Chris DuRoss, UGS • Comparison rupture extent of moment rates from GPS observations and late Quaternary earthquakes on the Wasatch faultBrigham City and Salt Lake City segments, Utah; Christine Puskas(b) long-term earthquake records for the northern Provo, UNAVCO • The Working Group on Utah Earthquake Probabilities (WGUEP)―Background, goalssouthern Weber, and progressSalt Lake City segments, and (c) the subsurface geometry and connection of the Warm Springs and East Bench faults on the Salt Lake City segment; Ivan Wong, URS Corporation • Basin (2) acquire long-term earthquake record for the West Valley fault zone – Taylorsville fault; and Range Province Earthquake Working Group II; Bill Lund, UGS • (3) improve the long-term earthquake record for Cache Valley (East and West Cache fault zone study; discussion leader Bill Lund, UGS A long-standing question exists regarding the status of the National Earthquake Hazard Reduction Program (NEHRP)-funded investigation titled Earthquake Timing on the Southern Segment of the East Cache Fault Zone, Utah by Utah State University (USUzones).

The Joes Valley fault zone and East Canyon faults are currently classified as Class A long-standing question exists regarding faults in the status Quaternary Fault and Fold Database of the National Earthquake Hazard Reduction Program United States. The Main Canyon (NEHRP)-funded investigation titled Earthquake Timing on the Southern Segment East of the East Cache Fault Zone, Utah by Utah State University (USU). Originally approved by NEHRP in 2007 Canyon) fault is classified as a one-year investigationClass B fault in the database. The definitions of Class A and B faults are as follows: Class A Geologic evidence demonstrates the existence of a Quaternary fault of tectonic origin, results whether the fault is exposed by mapping or inferred from liquefaction or other deformational features. Class B Geologic evidence demonstrates the existence of Quaternary deformation, but either (1) the study are fault might not yet extend deeply enough to be a potential source of significant earthquakes, or (2) the currently available geologic evidence is too strong to confidently assign the publicfeature to Class C, but not strong enough to assign it to Class A. A Class C fault is defined as: Class C Geologic evidence is insufficient to demonstrate (1) the existence of tectonic faulting, or (2) Quaternary slip or deformation associated with the feature. Cache Valley is one of Utah’s most populous regions off the Wasatch Front, and as such, The UQFPWG discussed the results of the USU investigation are important USBR paleoseismic and geologic investigations for the Joes Valley fault zone and East Canyon and Main Canyon faults, and whether or not the working group should make a recommendation to seismic-hazard reduction for the USGS to reclassify the Joes Valley fault zone and East Canyon fault as Class B faults and the Main Canyon fault as a Class A fault. Lucy Piety indicated that area.the USBR plans to continue studying the Joes Valley fault zone as funds and time permit (neither being presently available), because the USBR is not yet fully convinced that the fault zone is not seismogenic. Based on the USBR’s continued interest in the Joes Valley fault zone, the UQFPWG decided to withhold making a recommendation regarding fault reclassification pending the results of future USBR investigations. However, it should be noted that in 2004, the UQFPWG recommended to the USGS that they (1) combine all of the various groupings of the Joes Valley fault system into a single fault group, and
