Abstract

Three separate pulses were recognized on seismograms of ground motion resulting from explosions measured at distances ranging from 10 to 1,172 ft from the shotpoint. It is believed that the first pulse represents primarily body waves, the second pulse coupled waves, and the third pulse Rayleigh and Love waves arriving simultaneously. The ratios of the energies of the various pulses are given for several distances. The rates of attenuation of the three pulses are expressed as exponential functions and also as inverse power functions.
