DECOUPLING ESTIMATES FOR UNDERGROUND EXPLOSIONS.
Abstract
There is a considerable body of data, including all the direct P-Wave data from Project Cowboy, which indicates a decoupling factor of the order of two for a salt cavity compared to tamped alluvium or valley tuff. Cavities in soft rock probably do not decouple at all but increase the seismic signal. An increase in decoupling due to high frequency absorption appears unlikely, but should such an effect exist, decoupling factors would probably still be less than ten. Cavity decoupling may actually increase detectability because of the lower background noise at the higher frequencies produced by the cavity. (Author)
