Detailed consideration is given to utilization of earthquake-nuclear explosion seismological discrimination experience in a national operational verification procedure, but it is emphasized that such consideration in relation to clandestine underground nuclear explosions, or evasion tactics in general, is futile until all natural seismic activity can be identified down to the equivalent explosion yield. Thus the operational procedure becomes an earthquake screening process that can be simulation tested in advance of a Test Ban Treaty. The seismic region chosen is a major part of Eurasia and the monitoring nation is assumed to be Canada, although with the data exchange procedures inherent in the scheme it could be any nation. The seismic events considered are taken from the MIT Lincoln Laboratory bulletin, and these are subjected to three types of earthquake screening: (1) those with epicentres at sea, (2) those with focal depths greater than the maximum feasible drilling depth, and (3) those that are earthquake-like by wave discrimination criteria. In order to screen events using discrimination criteria a formal two-group discrimination analysis is used. (UK)
