Study of Selected Events in the Caucasus in a Seismic Discrimination Context

Abstract

Eight earthquakes from the Caucasus occurring from 1971 to 1975 were examined in a seismic discrimination context. Seismograms from ALPA, LASA, NORSAR, and the HGLP and the WWSSN stations were studied for source mechanism, (M sub s - M sub b), corner frequency, pP, complexity, and spectral ratio. All the Caucasus events can be identified as earthquakes by means of pP and M sub s:M sub b when compared to Kazakh and southwest USSR explosions. However it seems plausible that these discriminants could be rendered ineffective for events in the Caucasus by means of a shot array.
