Abstract
In this study further evidence of relative abundance of PcP (core reflected P) energy in explosion seismic records is gathered. It is based on the analysis of temporal and spectral characteristics of P and PcP digital seismograms of twenty-three underground nuclear explosions in Eastern Kazakh and Southern Russia recorded at Eskdalemuir (EKA) and Yellowkinfe (YKA) arrays. The results are compared with those obtained earlier using Gauribidanur array (GBA) data. It is found that seismic sources in Southwestern Russia give consistently large values of the PcP identifier when both EKA and YKA data are used thus corroborating authors` earlier finding with regard to this Soviet region of typical Q-structure inferred from GBA data. As regards relative levels of PcP energy in explosion generated seismic waves, it is found to be substantially large at GBA, moderate at YKA and least at EKA. (author). 8 figs., 3 tabs.
