Study of selected events in the Tien Shan region in a seismic discrimination context. Technical report

Technical Report ·
OSTI ID:7256713

Eleven earthquakes with low reported M(s) for their m(b) from the area near Lop Nor in the eastern Tien Shan were examined in a seismic discrimination context. Seismograms from ALPA, LASA, NORSAR, the HGLP and the WWSSN stations were studied for source mechanisms, M(s)-m(b), corner frequency, long-period body-wave excitation, pP, complexity, spectral ratio, and S/P excitation. All the events can be identified as earthquakes except the October 27, 1975 event which exhibits explosion characteristics. (Author)
