Book Synopsis Paleoseismic Investigation at Rock Canyon, Provo Segment, Wasatch Fault Zone, Utah County, Utah by : William R. Lund
Download or read book Paleoseismic Investigation at Rock Canyon, Provo Segment, Wasatch Fault Zone, Utah County, Utah written by William R. Lund and published by Utah Geological Survey. This book was released on 1998 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field work for this paleoseismic investigation at Rock Canyon was performed in 1988. It was one of three studies conducted in the late 1980s and early 1990s to determine if the Provo segment of the Wasatch fault zone should be subdivided into three smaller segments as tentatively proposed by Machette and others on the basis of their geologic mapping. This investigation was the last of the three studies performed. Those results, combined with the results of paleoseismic investigations at American Fork Canyon and Mapleton, showed that the Wasatch fault where it passes through Utah Valley probably consists of a single, almost 70-kilometer-Iong fault segment (Machette and others, 1992). Publication of the details of the Rock Canyon study has been delayed for several years, chiefly due to the press of new job duties on the part of the investigators. The information remains important and is presented here for the use of those individuals interested in earthquake hazards and seismic-source characteristics of the Wasatch fault in Utah Valley. 21 pages + 2 plates
Book Synopsis Consensus Preferred Recurrence-interval and Vertical Slip-rate Estimates by : William R. Lund
Download or read book Consensus Preferred Recurrence-interval and Vertical Slip-rate Estimates written by William R. Lund and published by Utah Geological Survey. This book was released on 2005-06-30 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Paleoseismic Investigation of the Clarkston, Junction Hills, and Wellsville Faults, West Cache Fault Zone, Cache County, Utah by : Bill D. Black
Download or read book Paleoseismic Investigation of the Clarkston, Junction Hills, and Wellsville Faults, West Cache Fault Zone, Cache County, Utah written by Bill D. Black and published by Utah Geological Survey. This book was released on 2000 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field work for this paleoseismic investigation was performed in 1997 at three sites (Winter Canyon, Roundy Farm, and Deep Canyon) on the Clarkston, Junction Hills, and Wellsville faults. These faults, along with several lesser associated faults nearby, comprise the West Cache fault zone on the west side of Cache Valley. No previous paleoseismic studies had been conducted on these faults. The information reported here on the size, timing, and recurrence of surface-faulting earthquakes on the West Cache fault zone is critical to public officials, planners, and others making decisions regarding earthquake-hazard mitigation in Cache Valley and the northern Wasatch front. 23 pages + 1 plate
Book Synopsis History of Late Holocene Earthquakes at the Willow Creek Site and on the Nephi Segment, Wasatch Fault Zone, Utah by : Anthony J. Crone
Download or read book History of Late Holocene Earthquakes at the Willow Creek Site and on the Nephi Segment, Wasatch Fault Zone, Utah written by Anthony J. Crone and published by Utah Geological Survey. This book was released on 2014-09-15 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Post-Provo Paleoearthquake Chronology of the Brigham City Segment, Wasatch Fault Zone, Utah by : James McCalpin
Download or read book Post-Provo Paleoearthquake Chronology of the Brigham City Segment, Wasatch Fault Zone, Utah written by James McCalpin and published by Utah Geological Survey. This book was released on 2002 with total page 53 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Paleoseismic Investigation on the Salt Lake City Segment of the Wasatch Fault Zone at the South Fork Dry Creek and Dry Gulch Sites, Salt Lake County, Utah by : Bill D. Black
Download or read book Paleoseismic Investigation on the Salt Lake City Segment of the Wasatch Fault Zone at the South Fork Dry Creek and Dry Gulch Sites, Salt Lake County, Utah written by Bill D. Black and published by Utah Geological Survey. This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The South Fork Dry Creek and Dry Gulch sites lie within a few hundred meters of each other in the southeastern part of the Salt Lake Valley, and together provide the only location on the heavily urbanized Salt Lake City segment of the Wasatch fault zone where it is possible to develop a complete surface-faulting chronology for the segment since middle Holocene time (the past 6,000 years). Investigations at the two sites took place intermittently between 1985 and 1995 as permission was obtained to trench more and more of the scarps within the broad fault zone. The new information reported here on the size, timing, and especially recurrence of surface-faulting earthquakes on the Salt Lake City segment shows that the earthquake hazard presented by this segment of the Wasatch fault is greater than previously thought. Such information is vital to public officials, planners, and others making decisions regarding earthquake-hazard mitigation. 22 pages + 1 plate

Book Synopsis 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH by : Steve D. Bowman
Download or read book 2016GUIDELINES FOR INVESTIGATING GEOLOGIC HAZARDS AND PREPARING ENGINEERING-GEOLOGY REPORTS, WITH A SUGGESTED APPROACH TO GEOLOGIC-HAZARD ORDINANCES IN UTAH written by Steve D. Bowman and published by Utah Geological Survey. This book was released on 2016-09-21 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of these guidelines for investigating geologic hazards and preparing engineering-geology reports, is to provide recommendations for appropriate, minimum investigative techniques, standards, and report content to ensure adequate geologic site characterization and geologic-hazard investigations to protect public safety and facilitate risk reduction. Such investigations provide important information on site geologic conditions that may affect or be affected by development, as well as the type and severity of geologic hazards at a site, and recommend solutions to mitigate the effects and the cost of the hazards, both at the time of construction and over the life of the development. The accompanying suggested approach to geologic-hazard ordinances and school-site investigation guidelines are intended as an aid for land-use planning and regulation by local Utah jurisdictions and school districts, respectively. Geologic hazards that are not accounted for in project planning and design often result in additional unforeseen construction and/or future maintenance costs, and possible injury or death.
