Paleoseismology of Utah Volume 2: Paleoseismic analysis of the Wasatch fault zone at Brigham City trench site, Brigham City, Utah, and the Pole Patch trench Site, Pleasant View, Utah (SS-76)

By: S. F. Personius

This UGMS Special Studies, the second in the Paleoseismology of Utah Special Studies series, consists of two reports by Stephen F. Personius of the U.S. Geological Survey (USGS) on fault-trenching studies of the north-central part of the Wasatch fault zone. The studies were undertaken as part of the joint USGS/UGMS Wasatch Front Earthquake Hazard and Risk Assessment Program, a 5-year research effort conducted under the auspices of the National Earthquake Hazard Reduction Program to evaluate earthquake hazard and risk along Utah's heavily populated Wasatch Front.

Trenching studies such as those reported here provide information on earthquake timing and recurrence, fault displacement, and fault geometry that is used to characterize seismic-source zones and to evaluate the long-term earthquake potential of active faults. The UGMS is doubly pleased to publish this special study, first, because it makes important paleoseismic information available to those charged with mitigating earthquake risk on the Wasatch Front, and second, because it is tangible evidence of the close cooperation that exists at the State and Federal levels on an issue that affects the life, safety, and well being of the citizens of Utah.
