In any negotiations between the United States and the USSR regarding possible new test ban treaties, the utility of in-country seismic monitoring stations for treaty verification will be a topic of considerable interest. At the request of the Treaty Monitoring Program at Lawrence Livermore National Laboratory (LLNL) has conducted a new evaluation to determine as accurately as possible the seismic activity rates and distributions of seismicity, magnitude, and depth for various geographic and geologic regions in the Soviet Union. This report describes the means used to develop this best estimate and the results of the analyses. In our determination of seismicity rates, we have made use of the best available seismicity catalogs. The seismic source zones to be used in the later seismicity analyses were then outlined, based on the locations of the Soviet regional networks and then compared with geologic and tectonic maps. In this report we will describe, in detail, the derivation of seismicity rates for each of these zones from seismicity catalogs using methods based on the empirical relation between earthquake magnitude and recurrence. 6 refs., 100 figs., 3 tabs.
