The extrapolation equations formulated prior to the Rainier Shot predicted with reasonable accuracy lowfrequency displacements in potash mines and at points near the Pre-Gnome explosions (Carlsbad, New Mexico area). The equations did not predict high accelerations associated with high-frequency ground waves resulting from these explosions. Accelerations and displacements of ground motion were found to vary directly as the first power of the weight of the explosives. Both accelerations at the surface and ground amplitudes from blasts in a mine were found to attenuate as the square of the distance. Seismic wave speeds in the salt were observed to be about 14,000 fps. (C.J.G.)
