Zusammenfassung:In this report, we describe specific research results in: (1) The theoretical basis for seismic event discrimination and for the inference of physical parameters describing seismic sources; (2) Observations of body wave magnitude residuals in the U.S. and Southern Canada and the implications for yield estimation at non-U.S. and/or U.S. test sites; (3) Inferences of magnitude-yield relationships for both U.S. and U.S.S.R. test areas, with applications of these relations to U.S. and Russian nuclear test observations, to obtain new yield estimates; (4) Studies of a variety of physical situations which would produce seismic observations for an earthquake making it appear anomalous (i.e., explosion-like) when viewed from the perspective of standard discrimination methods, and similarly physical situations were described for which explosions could appear earthquake-like, and which could also lead to large yield estimate errors.
