This research program is intended to provide a thorough assessment of the transportability of regional phase spectral ratios as discriminants between underground nuclear explosions and other source types. Although Lg spectral ratios appeared to offer considerable promise for distinguishing between nuclear explosions and nearby earthquakes based on experience from the vicinity of the Nevada Test Site, attempts to extend this spectral ratio discriminant into other geographic regions e.g. the vicinity of the SemipalatinskBalapan test site have not always proven to be successful. One of the main obstacles to demonstrating the value of regional phase spectral ratios as discriminants has been difficult in finding events of different source types with similar magnitudes and like propagation paths to enable direct comparisons of spectral ratio measurements.
