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

Abstract

Eleven earthquakes with low reported M sub s for their m sub b from the Northern Pamirs were examined in a seismic discrimination context. Seismograms from ALPA, LASA, NORSAR, 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 Parmir events can be identified as earthquakes when their characteristics are compared to those of Kazakh explosions. P-waves to NORSAR from these earthquakes exhibit very high frequency, and their spectral corner frequencies are not distinctly different from those of explosions.
