Contents include: boundary conditions for arbitrary polygonal topography in a 2-d elastic finite-difference scheme for seismogram generation; teleseismic spectral and temporal m/sub 0/ and psi/sub infinity/ estimates for four French explosions in southern Sahara; scattering from near-source topography: teleseismic observations and numerical 2-d explosive line-source simulations; effects of local geologic structure on Yucca Flats, NTS, explosion waveforms: 2-dimensional linear finite-difference simulations; and finite-difference simulations of Rayleigh-wave scattering by 2-d rough topography.
