Abstract:

The ort is an empirical study of the effects of large seismic motions on crater slopes. Data were obtained from measurements of the effects of the seismic motions generated by the Handley Event on the Cabriolet and Schooner craters. Accelerometers recorded the ground motions aerial photographs and ground surveys documented the permanent ground displacements. The Handley Event was detonated on Pahute Mesa at the Nevada Test Site approximately 10,000 ft from the Cabriolet crater and 18,000 ft from the Schooner crater. The slopes at Cabriolet were subjected to the estimated peak radial horizontal acceleration of 0.74 g the slopes at Schooner, to 0.36 g. Material displacements at Cabriolet and Schooner craters were confined to the loose surface material and individual boulders. Author
