Evaluation of the RSTN (Regional Seismic Test Network) Network and Further Improvement to Automatic Association.
Abstract
The Regional Seismic Test Network (RSTN) is a 5-station seismic network designed to monitor regional seismicity on the scale of a large continental shield. The RSTN serves as a prototype for a network that could be deployed for test ban treaty verification. Both regional and teleseismic signals are digitally recorded for three components of earth motion in three overlapping frequency bands covering 0.02 to 10 Hz. The approach of this study was to select 9 events recorded by the network and manually analyze the recordings using available software at the CSS. Various phases were identified and picked as well as possible, back azimuths were estimated, and signal-to-noise ratios were determined. Finally, detection thresholds as a function of distance were estimated for P, Lg and L sub R phases using the signal-to-noise ratios of the 9 events. Several existing CSS software packages were tested using the RSTN evaluation data.
