Abstract
This study proposes a mathematical-statistical model for discrimination between earthquakes and nuclear explosions. The initial formulation defines the source parameters relating to geometry of the focus and of the source mechanism, the earth layering and heterogeneity parameters, and the principal types of waves that are propagated. A method of analysis of seismograms is proposed which can extract information from sources not ordinarily used, namely arrival times and amplitudes of secondary body phases. The principal problem areas relating to identification of phases and precision station calibration are discussed in detail. Finally, methods for probabil1ty evaluation of the discrimination procedures are discussed.
