The U. S. Geological Survey monitored three highexplosive test shots at the Gnome site during the PreGnome experiments and monitored routine blasting in the potash mine of the Duval Sulphur and Potash Company. The motion in the potash mines near Carlsbad from a shot of 9 kt of TNT at the Gnome site, 46,000 feet from the nearest potash mine, is given. These particle velocities and accelerations are less than those recorded at a distance of 90 feet from a routine 75-pound dynamite blast in a potash mine. (auth
