Teleseismic ground motion predictions for the recent Pahute Mesa explosion, MAST, were quite successful in terms of both amplitude and waveform matching. The predicted short-period body wave amplitudes were within 30 to 50 percent of the observed amplitudes at most of the SDCS stations. In addition, the general character of the first few seconds of the P-wave trains at the various SDCS stations were matched in reasonable detail. A tension failure model that describes the development of a region of enhanced tension failure (cracking) produced during stress release behind the interacting shock fronts from closely spaced explosions was developed. Calculations for a multiple explosion scenario (three closely spaced explosions detonated simultaneously) were carried out into the elastic region using the two-dimensional CRAM code with the new material failure model included.
