Simulation of the detection and location capability of regional seismic networks in the Soviet Union. Final report, 1 Jan 89-31 Dec 90
The main objective of this two-year project is to assess the treaty monitoring capability of existing and proposed seismic networks in the Soviet Union. We estimate the number of in-country single stations or arrays that are required to monitor nuclear explosion testing to a threshold of 1 kt. This corresponds to an approximate magnitude of 2.5 if the explosion is fully-decoupled. We estimate that 10 internal NORESS-type arrays or 30 internal IRIS-type single stations are required to achieve a 90% detection threshold of ML 2.5 throughout the Soviet Union. However, only 15 in-country single stations are needed to reach this threshold in regions of bedded or domed salt (e.g., regions for which full-decoupling is feasible). These estimates are based on detection of 3 phases involving at least 2 stations, which gives location uncertainties = or < 20 km at the 90% confidence level.
