The objective of this project was to measure and analyze ground shock in the outrunning region produced by the 500-ton Dial Pack detonation. Motions and stresses were measured at 645- and 840-foot ground ranges at depths of 1.5, 5, 10, and 20 feet. Thirty-one of thirty-two gages produced good records; time histories are included in Appendixes A and B, and frequency response spectra are presented in Appendix C. (Modified author abstract).

The objectives of this study were to measure and to analyze the earth motions and stresses produced by the Dial Pack 500-ton TNT detonation. Particle acceleration, particle velocity, and soil stress gages were installed to measure the ground motions and stresses in the 1,500- to 50-psi predicted air-blast overpressure region (83 to 540 feet from ground zero) at depths below the ground surface of 1.5 to 30 feet. Time histories of all successful measurements are included in Appendixes A and B. Ground shock arrival time data indicated the occurrence of outrunning ground motion at the ground surface at a distance of about 600 feet from ground zero, or the 35-psi pressure level.
