Abstract:The 2022-04-06 Xingwen MS5.1 earthquake triggered three seismic monitoring instruments laid on the shatter slope in Gongxian county, Yibin city, and the seismic wave propagation data was completely recorded. Through data filtering and baseline correction, we analyze the time history curve, Fourier spectrum and acceleration response spectrum. The results show that: 1) The holding time of this earthquake is short, the amplitude is small, and the S-wave holding time of the 2# and 3# monitoring points is 2-5 s longer than that of the 1# monitoring point. 2) Fourier spectrum shows low frequency attenuation, medium and high frequency amplification, and frequency band widening in the horizontal direction, but the change in the vertical direction is not obvious. 3) Take the 1# monitoring point as reference, the peak acceleration(PGA) amplification coefficient of 2# and 3# monitoring points is 1.17-3.05, the Arias intensity(AI) amplification coefficient is 4.43-7.59 in the EW and UD directions, and the NS direction of the 3# monitoring point can reach 18.86. 4) Compared with the monitoring profile of Renjia village(non-shatter slope) in Lushan, we believe that there is an amplification effect of the Gongxian shatter slope.
