Two agencies in Utah share the principal responsibility for the study of and scientific response to earthquakes in the state. The University of Utah Seismograph Stations operates the seismic monitoring network and determines the earthquake's location, magnitude, and focal mechanism. The Utah Geological Survey evaluates geologic effects through field reconnaissance immediately following the earthquake. In addition, the Utah Division of Comprehensive Emergency Management helps coordinate the emergency response and, for damaging earthquakes, documents losses. Following each significant earthquake in Utah for which geologic and seismologic studies are undertaken, the Utah Geological Survey will publish a summary report. This is the first such report.
The report is a compilation of papers regarding the March 16, 1992 ML 4.2 Western Traverse Mountains earthquake in the southern Salt Lake Valley. In the first paper, Christenson and Olig give an overview of the earthquake and summarize some of the more detailed information in papers that follow. Next, Pechmann discusses the focal mechanism and seismotectonic aspects of the earthquake. Olig and Mulvey report on investigations after the earthquake for geologic effects, and Harty discusses in more detail the evidence for possible earthquake-induced liquefaction at one locality. Individual papers have been formatted with some minor editing for inclusion in this report. An accelerograph record from a site at the north end of the Oquirrh Mountains was provided by Kennecott Utah Copper and is included in the appendix
