  • Abstract:
    The purpose of this project was to install a downhole array of force-balance accelerometers (FBA’s) at a free-field site near large bridge structures in the interchange between I-15, I-80, and Highway 201 in Salt Lake City, Utah. The street address for this site is near 600 West and 2200 South. The array includes four downhole FBA’s installed at depths of 25 ft, 60 ft, 160 ft, and 390 ft (7.6 m, 18.3 m, 48.8 m, and 119 m), respectively. A surface FBA was previously installed near the downhole array. The downhole array was completed on April 18, 2003 and has been operational since that date. Seismic ground motions monitored by the downhole array are collected, processed and distributed by the University of Utah Seismograph Stations (UUSS). Maintenance for the array is provided under a UDOT interagency agreement with the US Geological Survey (USGS).
