Abstract : This report presents a summary of the initial results of an on-going joint research program in which S-CUBED scientists are working with Russian scientists from the Institute for Dynamics of the Geospheres in an attempt to develop a better understanding of the effects of cavity decoupling on the seismic signals produced by underground nuclear explosions. This program includes analyses of seismic data recorded from a series of 10 tamped and 12 decoupled HE tests which were conducted in cavities of different sizes and shapes in Kirghizia in 1960, a theoretical evaluation of the influence of radiation diffusion effects on nuclear cavity decoupling efficiency and an analysis of data recorded from six small (0.01 to 0.50 kt) Russian nuclear tests conducted in a 32 % radius, water-filled cavity in salt at the Azgir test site.
