- Abstract:
- Taking the acceleration recording of Ludian MS6.5 earthquake on Aug.3,2014 in Yunnan province as the studying samples,we analyzed duration time and the crossing-zero rates on its three-component acceleration history of strong motion respectively.After studying the frequency characteristic differences of the three-component recordings,we summarized the duration dispersion characteristic of the relative peak value of the three-component strong motion recording of Ludian MS6.5 earthquake,and the trend variation of zero crossing rate with epicenter distance.Finally,we focus on analyzing the non-stationarity variation of the frequency of strong motion.
