Project DANNY BOY. Earth-Motion Measurements
The objective of Danny Boy Project 1.2 was to measure ground motion resulting from an underground nuclear detonation in basalt. This report presents and analyzes the measurements obtained from 31 vertically and horizontally oriented accelerometers and 3 vertically oriented velocity meters. The accelerometers and velocity meters were placed in the region extending horizontally from 3 to 610 meters from Surface Zero (SZ). All were placed near the surface (i.e. at depths of about 1/3 meter) except the accelerometer at the 3-meter station which was buried 18.3 meters deep. Peak acceleration values were considerably less than anticipated. Because of low amplifier gain settings used in anticipation of higher signal levels, usable records were obtained on only 22 channels. However, because of the low acceleration levels, close-in measurements (i.e. close to SZ), which were of primary interest, were successfully made.
