Book excerpt: This Utah Geological Survey Miscellaneous Publication, Post-Provo Paleoearthquake Chronology of the Brigham City Segment, Wasatch Fault Zone, Utah, is the eleventh report in the Paleoseismology of Utah series. This series makes the results of paleoseismic investigations in Utah available to geoscientists, engineers, planners, public officials, and the general public. These studies provide critical information on paleoearthquake parameters such as timing, recurrence, displacement, slip rate, and fault geometry which can be used to characterize potential seismic sources and evaluate the long-term seismic hazard presented by Utah’s Quaternary faults. This report presents the results of the most extensive single paleoseismic-trenching project yet conducted on the Wasatch fault zone. The purpose of the study was to lengthen the paleoseismic chronology for the Brigham City segment of the Wasatch fault zone beyond the 6,000-year record previously available, and to resolve questions regarding the irregular pattern of paleoearthquakes reported by earlier workers for the Brigham City segment. This study makes extensive use of radiocarbon, thermoluminescence, and infrared stimulated luminescence dating techniques to develop a real-time chronology of past surface-faulting earthquakes.
