Abstract : The primary purpose of Project DRIBBLE is to test the theory that exploding a charge at the center of a spherical cavity of proper size will muffle the explosion to such an extent that little of its energy will be converted into seismic waves. This is called the 'decoupling theory' and the proposed test program includes three explosions: SALMON, TAR, AND SAND. The SALMON event, a coupled 5-kiloton explosion, was to provide data on the fully tamped case and to allow observation of effects of propagation of seismic waves from the salt dome to large distances. The direct decoupling measurements are to be obtained from the detonation of two 100-ton devices, one fully tamped (TAR) and one in a cavity of the appropriate size (SAND). Both of these events still require final approval. Measurements from these two events will allow a direct determination of the decoupling effect and scaling of the data from SALMON and TAR (the fully tamped events) will allow an estimate of the decoupling expected for a 5-kiloton explosion detonated in a cavity.
