- Abstract:
- A major earthquake of MS5.0 and aftershock of MS5.0 occurred successively on August 13 and 14,2018,Tonghai County,Yunnan Province.There are 41 and 30 strong motion stations which located in this region have been fully triggered in the main and aftershock.213 records of three-component acceleration were obtained by NSMONS.In this paper,we first calculate the peak accelerations of the 213 strong motion records.The basic characteristics of amplitude in this earthquake were analyzed according to the acceleration time-series curves and contour line of PGAs.Then,the attenuation relationship of PGAs with different distance was analyzed by comparing the observed data with some commonly used GMPE(ground motion prediction equations).In order to summarize the characteristics of response spectrum,we compare the acceleration response spectra of some typical stations with the designed spectrum.The HVSR method has been used to analyze site effect and judge whether nonlinear response occur of 3 typical stations with main and multiple aftershocks records.
