Abstract : This report summarizes work accomplished by the Air Force Weapons Laboratory during the period May 1981 to April 1982. The purpose of this work has been to focus on seismic source characterizations of explosive sources. Specifically, we have investigated the usefulness of the moment tensor representation in modeling near-field recordings of contained nuclear explosions. Extension of the source representation to surface explosions utilizing the zeroth order moment has also been accomplished. In an attempt to investigate the possibility of using small scale high-explosive tests in studying source characterization problems, a 256-pound fully contained chemical explosion was instrumented and detonated. A preliminary data report. is included while data analysis is ongoing. Further studies of small scale surface and buried chemical explosions are outlined in. Reflectivity modeling of the observational data was attempted.
