The Formation of Seismic Waves in the Ground near the Surface during an Explosion,
Abstract
Laboratory experiments have been made on movements of a medium near the charge during explosions at ground surface. Movements were measured at the edge of the crater and immediately next to this on the surface and within the mass. All experimental results confirm the opinion that it is impossible to represent an explosion near the free surface as a spherical symmetrical center of expansion. Particle trajectories were measured in modeling clay, pressed between two thick steel plates, one of which had a plastic window. This placing of the charge led to almost complete release of energy toward the clay. Trajectories for individual points at the edge of the crater and beyond are shown for a charge of 0.4 g and charge depth of 40mm. (Author)
