On 6 August 2007 a local magnitude 3.9 seismic event occurred at 08:48:40 UTC in central Utah. The epicenter is within the boundaries of the Crandall Canyon coal mine (cf. Pechmann et al. 2008, this issue of SRL). We performed a moment tensor analysis with complete, three-component seismic recordings from stations operated by the U.S. Geological Survey (USGS), the University of Utah, and EarthScope. The analysis method inverts the seismic records to retrieve the full seismic moment tensor, which allows for interpretation of both shearing (e.g., earthquakes) and volume-changing (e.g., explosions and...
