- Underground nuclear explosions—Detection—Congresses;
This article deals with the effects of high-explosive and nuclear explosions in rock masses. We first highlight the strong influence of geological discontinuities, such as joints and faults, on ground motion characteristics, using two examples. Then, we briefly introduce the Discrete Element method, as a new technique for numerical simulations. It is shown to be far superior to continuum-based approaches, when dealing with the dynamics of discontinuous media such as jointed rocks. Finally, we present a two-dimensional simulation of the ground effects from a generic contained nuclear explosion, which bears some similarity to the SHOAL event in granite. This calculation is intended to emphasize the influence of the near-source geology on the distribution of energy, and on the motion at various azimuths in the medium. These results are relevant to questions arising in the context of Treaty Verification by seismic means.
