Abstract:

The results of calculation of the cratering and ground motion for a 5-Mt nuclear surface burst over a layered geology are described. This calculation included a full description of the energy source and thus the direct-, cratering- and airblast-induced ground motion. The calculations was performed to a real time of 2.1 seconds, and the ground motion waveforms for scaled ranges as small as 6 x cube root of the volume exhibited a distinct Rayleigh wave.
