Abstract : Preliminary modeling and experimental studies have been conducted to determine the source discrimination capabilities of joint seismic and electromagnetic observations for application to nuclear test monitoring. The proposed source discriminant is based on the premise that the seismic to atmospheric acoustic pulse ratio is a measurable parameter sensitive to the source mechanism. In particular, it is suggested that underground nuclear explosions have a proportionately greater seismic to acoustic pulse ratio than do relatively shallow industrial noise sources such as conventional mining and quarry explosions.
