We present a combined catalog of seismic and acoustic events within the vicinity of Utah in 2011. Focusing on the Bingham Copper Mine, an area with many mining blasts, we group seismoacoustic events. For events detected at multiple acoustic arrays, grouping was based on origin time and location. For events detected at only one acoustic array, grouping was based on trace velocity and backazimuth. Here we quantify differences in origin time and location, comparing these to event type and magnitude estimated from seismic data. Ul-timately, we show that the use of a combined seismoacoustic catalog leads to a better understanding of the nature of individual events.
