Abstract:

Five seismograph systems that are routinely operated at the Uinta Basin Seismological Observatory were evaluated to determine their relative capabilities in detecting teleseismic P-wave arrivals. This evaluation includes a detailed analysis of microseismic background noise, signal characteristics, and signal-to-noise ratios, as recorded on a single element of the surface array of seismographs, both the filtered and unfiltered summation of the outputs of the elements of the surface array, the shallow-hole, and the deep-hole seismograph systems. In addition, system magnitude residuals relative to magnitudes reported by the USC and GS as well as apparent arrival time residuals are presented.
