Deismic event detection over extended bandwidths and the definition of the DSVS (Deployable Seismic Verification System) receiver. [Deployable Seismic Verification System]
Prior to 1985 seismic stations installed on a long term basis to evaluate underground nuclear test ban monitoring concepts had been limited to observations beneath 16 Hz. In early winter of 1985 the installation of a simple three component station having a seismometer handwidth extending between 3 and 53 Hz has afforded a unique opportunity to evaluate the characteristics and utility of seismic observations over an extended bandwidth for an extended period. The station is located in the center of the NORESS array in southeastern Norway. Subsequent studies of observations from this high frequency (hf) station had revealed the characteristics and potential of extended bandwidths to the seismic monitoring problem. The work reported here empirically and theoretically demonstrates how the receiver bandwidth, configuration, and response affect the performance of a simple monitoring station. The results are directly applicable to specifying the receiver characteristics for the Deployable Seismic Verification System (DSVS) and to demonstrating the detection performance capability of simple DSVS stations. 9 refs., 33 figs., 2 tabs.
