Abstract:

The report summarizes the results of the second three months of research on a contract whose main objective is to examine the parameters that effect the seismic signals from underground nuclear explosions. Results were presented on research in five areas 1. Data pertinent to regional bias in M sub b and M sub S in the United States and central Asia were summarized 2. Signals simulating those from multiple explosions were decomposed and scaled by narrow-band filtering methods 3. Numerical simulations of contained explosions were compared with previous laboratory simulations 4. Laboratory experiments of cratering explosions were completed using 0.25 gram charges embedded in concrete and 5. The primary factors controlling amplitude-yield scaling at regional distances were investigated.
