Seismic Studies for Improved Yield Determination
Abstract
The main objective of this contract is to examine the parameters that affect the seismic signals from underground explosions. Results are presented from research in five areas: (1) Theoretical teleseismic magnitudes (M sub s and m sub b) were determined for a series of nuclear explosion cratering calculations; (2) The relative frequency content of signals from U.S.S.R. and U.S. explosions were studied by comparing the periods of the first few cycles of recordings from several stations at teleseismic ranges; (3) Some improved techniques were developed for computing the equivalent point source representation for explosions in highly porous materials; (4) The dependence of body wave magnitude on yield for underground explosions in salt was studied and compared to that for explosions in granite; and (5) Small scale experiments were carried out in which underground explosions were modeled by 0.25 gram charges embedded in concrete.
