Summary
We performed numerical simulations of three nuclear testing evasion scenarios. These calculations were done in two parts. The first part was done near source (within 10 km) with a non-linear weapons effects code. Particle velocity histories from the non-linear code were linked to an elastic linear finite-difference code for the second part. Seismic waveforms from the evasion scenario calculations were compared with the waveforms for a non-evasive explosion calculation at near regional distances. The results of this comparison suggest that it may be important to include realistic stratigraphy in such simulations: the overall wave amplitude in the present simulations is reduced by only a factor of 3-5 in contradiction to factors of 20-100 in {open_quotes}classical{close_quotes} decoupling analyses for ideal (i.e., unlayered) media. Two of the evasion scenarios simulated retain explosive waveform characteristics at near regional distances, while the third scenario indicates that certain source geometries might lead to more non-explosive (i.e., earthquake-like) seismic signals.
