SEISMIC AMPLITUDES AT AN INTERMEDIATE RANGE FROM EXPLOSIONS

Short-period seismic waves from the Nevada Test Site shots have been recorded by Sandia Laboratory's four-station seismic net during the past 2 1/2 years. Epicentral distances vary from 130 to 240 kilometers. Raw maximum wave amplitudes usually vary as the yield to the 0.8 to 1 power. The medium in which the detonation takes place influences the magnitude of the seismic signals. Shots in dry alluvium produce the smallest seismic signals, while those in granite give the largest signals observed. Both the P-phase amplitude and its ratio to the S-and-surface-phase amplitude vary notably with travel path.
