There is an observed variation in body wave magnitude of approximately or - 0.2 units for explosions in different areas of Yucca Flat, NV. The variation appears to correlate with the Cenozoic basin structure at Yucca Flat. The basin has been modeled geophysically by Ferguson unpublished manuscript. In this study it is hypothesized that the variation in m sub b is caused by scattering or resonance effects within the local geologic structure. This conjecture has been investigated by computation of synthetic teleseismic P-wave amplitude responses for the Yucca Flat geophysical mode. The tech. due to Aki and Larner was used. Good quantitative agreement with observations was found. Author
