A procedure for directly inverting teleseismic ground motion data in order to obtain estimates of explosion yields was developed. The particular inversion scheme employs a deterministic modeling capability which predicts the teleseismic ground motion from a nuclear explosion. This procedure supplements expected data exchange packages that provide information on the near explosion source environment. Experiments involving computer simulation decomposition of multiple explosion scenarios were recently initiated. Application of narrow band filtering to synthesized multiple event seismograms has yielded accurate determinations of the relative amplitudes and time separations between individual explosions in the multiple explosion event examined. Preparations are nearing completion for a series of three-dimensional seismic modeling experiments. The intent of these experiments is to measure differences in signals between single and multiple sources and between near surface and deeply- buried sources. Theoretical explosion calculations will be compared to the experimental results.
