Multiple Seismic Events

Abstract

The report deals with an investigation of multiple seismic events and first zone discriminants. Spectral analyses were made for several nuclear shots and an earthquake that had the same general transmission paths between source region and recording stations. The results of these studies showed that the mean slope of the nuclear event spectra in the frequency range from 1.0 to 0.135 Hz is negative, while the mean slope for the earthquake over the same frequency range is zero. Cross-correlation studies were initiated between different nuclear shots recorded at the same stations and between an earthquake and nuclear shots for the same stations. The study of secondary arrivals by use of Cepstrum analyses was continued during this report period.
