Abstract
In May 2006, the University of Utah Seismograph Stations, as part of a larger consortium, installed an infrasound array east of the Salt Lake Valley (NOQ). Infrasound can be thought of as seismology in the air focusing on subaudible acoustic signals in the frequency band from 0.01 to 20 Hz. Advantages of installing an infrasound array in northern Utah include a proximity to solid earth sources (mine blasts and earthquakes) and the possibility of incorporating the data into a regional seismic network. The primary application of infrasound is in identification of explosions detonated at or near the solid earth‐atmosphere boundary. However, to fully utilize the infrasonic data, better understanding of infrasonic source characteristics and propagation is needed. Goals of the infrasound installation at NOQ include (1) use of local ground truth information to assess the role of infrasound in source identification; (2) classifying properties of the infrasound signal by source type; (3) assessing the time varying...
