This publication presents probabilistic earthquake forecasts developed by the Working Group on Utah Earthquake Probabilities which developed 30,50, and 100 year forecasts that include combined time dependent probabilities of large earthquakes for the five central segments of the Wasatch Fault Zone.

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.

This report consolidates and synthesizes information on Quaternary faulting, folding, and volcanism in Utah and characterizes recent tectonic activity throughout the state. The primary purpose is to provide a comprehensive reference on fault-specific seismic sources and surface rupture to facilitate the evaluation of earthquake hazards in Utah. Two 1:500,000-scale maps show Quaternary tectonic features categorized according to probable ages of most recent surface deformation and ages of volcanic rocks. Two appendix tables summarize significant data on the activity of mapped features, including ages of surface displacements and volcanism, slip rates, recurrence intervals, displacement amounts, and lengths of surface ruptures. Good age control and quantitative activity data are available for relatively few tectonic features in Utah and detailed work is needed in many areas of the state. 157 pages + 2 plates

The Rapid Visual Screening (RVS) handbook can be used by trained personnel to identify, inventory, and screen buildings that are potentially seismically vulnerable. The RVS procedure comprises a method and several forms that help users to quickly identify, inventory, and score buildings according to their risk of collapse if hit by major earthquakes. The RVS handbook describes how to identify the structural type and key weakness characteristics, how to complete the screening forms, and how to manage a successful RVS program.

A journey around the United States in search of the truth about the threat of earthquakes leads to spine-tingling discoveries, unnerving experts, and ultimately the kind of preparations that will actually help guide us through disasters. It’s a road trip full of surprises. Earthquakes. You need to worry about them only if you’re in San Francisco, right? Wrong. We have been making enormous changes to subterranean America, and Mother Earth, as always, has been making some of her own. . . . The consequences for our real estate, our civil engineering, and our communities will be huge because they will include earthquakes most of us do not expect and cannot imagine—at least not without reading Quakeland. Kathryn Miles descends into mines in the Northwest, dissects Mississippi levee engineering studies, uncovers the horrific risks of an earthquake in the Northeast, and interviews the seismologists, structual engineers, and emergency managers around the country who are addressing this ground shaking threat. As Miles relates, the era of human-induced earthquakes began in 1962 in Colorado after millions of gallons of chemical-weapon waste was pumped underground in the Rockies. More than 1,500 quakes over the following seven years resulted. The Department of Energy plans to dump spent nuclear rods in the same way. Evidence of fracking’s seismological impact continues to mount. . . . Humans as well as fault lines built our “quakeland”. What will happen when Memphis, home of FedEx's 1.5-million-packages-a-day hub, goes offline as a result of an earthquake along the unstable Reelfoot Fault? FEMA has estimated that a modest 7.0 magnitude quake (twenty of these happen per year around the world) along the Wasatch Fault under Salt Lake City would put a $33 billion dent in our economy. When the Fukushima reactor melted down, tens of thousands were displaced. If New York’s Indian Point nuclear power plant blows, ten million people will be displaced. How would that evacuation even begin? Kathryn Miles’ tour of our land is as fascinating and frightening as it is irresistibly compelling.

Published by the American Geophysical Union as part of the Maurice Ewing Series, Volume 4. From May 12 to May 16, 1980, eighty-eight scientists from eleven countries attended a Symposium on Earthquake Prediction at Mohonk Mountain House, Mohonk, New York. This was the third in a biennial series honoring Maurice Ewing, first director of Lamont-Doherty Geological Observatory. The Symposium was one of several events that were held in 1980 to celebrate the 100th anniversary of the Graduate School of Arts and Sciences at Columbia University. The two earlier Ewing Symposia, on island arcs and deep sea drilling, reflected Ewing's lifelong interest in the structure and evolution of the ocean floor. In the Third Ewing Symposium we touch another area—earthquake seismology—that played an important part in Ewing's career. Work on surface waves and long-period seismology under Ewing's direction during the 1950's and 1960's, along with his exploration of the earth beneath the oceans, provided much of the framework on which current ideas on earthquake generation and plate tectonics are based.

The destructive force of earthquakes has stimulated human inquiry since ancient times, yet the scientific study of earthquakes is a surprisingly recent endeavor. Instrumental recordings of earthquakes were not made until the second half of the 19th century, and the primary mechanism for generating seismic waves was not identified until the beginning of the 20th century. From this recent start, a range of laboratory, field, and theoretical investigations have developed into a vigorous new discipline: the science of earthquakes. As a basic science, it provides a comprehensive understanding of earthquake behavior and related phenomena in the Earth and other terrestrial planets. As an applied science, it provides a knowledge base of great practical value for a global society whose infrastructure is built on the Earth's active crust. This book describes the growth and origins of earthquake science and identifies research and data collection efforts that will strengthen the scientific and social contributions of this exciting new discipline.
