Neotectonics of Bear Lake Valley, Utah and Idaho by James McCalpin Pdf

This report presents the results of a preliminary evaluation of the East Bear Lake (EBF) and West Bear Lake (WBF) fault zones, which bound the east and west sides, respectively, of the Bear Lake Valley. The Bear Lake Valley straddles the Utah/Idaho border northeast of Logan, Utah. The results of this study show that both the EBF and the WBF have experienced surface-faulting earthquakes in the recent geologic past and therefore represent an ongoing seismic hazard to northeastern Utah and southeastern Idaho.

Paleoenvironments of Bear Lake, Utah and Idaho, and Its Catchment by Joseph G. Rosenbaum,Darrell S. Kaufman Pdf

Bear Lake is located 100 km northeast of Salt Lake City and lies along the course of the Bear River, the largest river in the Great Basin. The lake, which is one of the oldest extant lakes in North America, occupies a tectonically active half-graben and contains hundreds of meters of Quaternary sediment. This volume is the culmination of more than a decade of coordinated investigations aimed at a holistic understanding of this long-lived alkaline lake in the semiarid western United States. Its 14 chapters, with 20 contributing authors, contain geological, mineralogical, geochemical, paleontological, and limnological studies extending from the drainage basin to the depocenter. The studies span both modern and paleoenvironments, including a 120-m-long sediment core that captures a continuous record of the last two glacial-interglacial cycles.

Consensus Preferred Recurrence-interval and Vertical Slip-rate Estimates by William R. Lund Pdf

This report presents the results of the Utah Quaternary Fault Parameters Working Group (hereafter referred to as the Working Group) review and evaluation of Utah’s Quaternary fault paleoseismic-trenching data. The purpose of the review was to (1) critically evaluate the accuracy and completeness of the paleoseismictrenching data, particularly regarding earthquake timing and displacement, (2) where the data permit, assign consensus, preferred recurrence-interval (RI) and vertical slip-rate (VSR) estimates with appropriate confidence limits to the faults/fault sections under review, and (3) identify critical gaps in the paleoseismic data and recommend where and what kinds of additional paleoseismic studies should be performed to ensure that Utah’s earthquake hazard is adequately documented and understood. It is important to note that, with the exception of the Great Salt Lake fault zone, the Working Group’s review was limited to faults/fault sections having paleoseismic-trenching data. Most Quaternary faults/fault sections in Utah have not been trenched, but many have RI and VSR estimates based on tectonic geomorphology or other non-trench-derived studies. Black and others compiled the RI and VSR data for Utah’s Quaternary faults, both those with and without trenches.

History of Late Holocene Earthquakes at the Willow Creek Site and on the Nephi Segment, Wasatch Fault Zone, Utah by Anthony J. Crone,Stephen F. Personius,Christopher B. DuRoss,Michael N. Machette,Shannon A. Mahan Pdf

This 43-page report presents new data from the Willow Creek site that provides well-defined and narrow bounds on the times of the three youngest earthquakes on the southern strand of the Nephi segment, Wasatch Fault zone, and refines the time of the youngest earthquake to about 200 years ago. This is the youngest surface rupture on the entire Wasatch fault zone, which occurred about a century or less before European settles arrived in Utah. Two trenches at the Willow Creek site exposed three scarp-derived colluvial wedges that are evidence of three paleoearthquakes. OxCal modeling of ages from Willow Creek indicate that paleoearthquake WC1 occurred at 0.2 ± 0.1 ka, WC2 occurred at 1.2 ± 0.1 ka, and WC3 occurred at 1.9 ± 0.6 ka. Stratigraphic constraints on the time of paleoearthquake WC4 are extremely poor, so OxCal modeling only yields a broadly constrained age of 4.7 ± 1.8 ka. Results from the Willow Creek site significantly refine the times of late Holocene earthquakes on the Southern strand of the Nephi segment, and this result, when combined with a reanalysis of the stratigraphic and chronologic information from previous investigations at North Creek and Red Canyon, yield a stronger basis of correlating individual earthquakes between all three sites.
