Abstract:

Three microseismic stations were operated by the U. S. Army Engineer Waterways Experiment Station WES during the Pre-GONDOLA I cratering calibration series at Fort Peck, Montana. The seismic stations, located in the center of the dam, the Gate Control Structure No. 3, and on the spillway, were monitored for the purpose of determining structure response resulting from the 20-ton charges detonated approximately 12 miles from the dam. Particle velocity data were recorded simultaneously on oscillographs and magnetic tape. Oscillograms were analyzed for maximum transient zero to peak particle velocities, and the tape was subjected to linear and power spectral density analysis from 0.5 to 20 Hz over a period of 160 sec.
