Fatigue Damage Analysis of Seismic Vibration Signals Associated with 2001 MS 8.1 Western Kunlunshan Pass Earthquake
Abstract The high precision and sampling acquisition rate observing system of broadband digital seismometer shows that broadband digital signal contains rich crustal movement and damage information. However, the information remains to be further excavated. The broadband digital data of WMQ, LSA, ENH, KMI and XAN stations are analyzed based on fatigue damage theory, for a few days before the November 14, 2001 earthquake at western Kunlunshan pass. The results show that the relative stress of the stations increases significantly in the days before the earthquake.
Key words ：
