In negotiation of a nuclear test ban treaty, signatory parties must have confidence clandestine nuclear testing can be detected. Seismic arrays offer promise in providing the detection coverage needed to monitor a large country such as the Soviet Union while using a small number of ''stations.'' To test aspects of seismic array performance as potential treaty verification ''stations,'' an experiment was conducted with a seismic array in southeastern Kansas. The site was chosen on the basis of seven site selection criteria: geologic analog to Soviet Union geology, depth to bedrock, regional seismic sources, background seismic noise level, land accessibility, subsurface geologic features and other seismic stations in the vicinity. The array deployment consisted of thirteen three component stations located in a particular geometry over four square kilometers. All stations were mounted on bedrock and protected from water intrusion and wind noise. Data was digitized and telemetered to a central recording trailer. Data, shipped to LLNL, will be analyzed to test spatial stationary and scaling with respect to array performance measures such as array gain, spatial coherence, bearing estimation error, and phase velocity estimation error.
