FREE-FIELD GROUND MOTION STUDIES IN GRANITE

Abstract

Ground motion was observed at six stations between 256- and 784-foot range along a horizontal radius from the Hard Hat nuclear explosion in granite. Primary instrumentation comprised accelerometers oriented to respond to radial motion. Velocity and displacement gages backed up the accelerometers at five stations. At the two most remote stations, accelerometers and velocity gages were installed to respond to three orthogonal components of motion, radial, vertical, and tangential, the latter two directions being transverse to wave propagation.
