Abstract
Taking the Qingyuan MS4.3 earthquake in Guangdong on June 23,2025 as an example,the coseismic response data recorded by VP vertical pendulum and JQY-1 vertical pendulum in the Guangdong region were analyzed,and the coseismic response characteristics of the two were compared and analyzed.The results show that the maximum response amplitude,initial movement time,response duration,and coseismic morphology recorded by the two types of vertical pendulum inclinometers have certain regularity and differences.The spectral dynamic evolution process of the entire coseismic period was studied using the S-transform method.The results show that the frequency band of the JQY-1 vertical pendulum coseismic wave is between 0.01 and 0.03 Hz,and the energy is concentrated around 0.02 Hz.The VP vertical pendulum is located at 0.01-0.03 Hz and 0.35-0.45 Hz,with energy concentrated around 0.02 Hz and 0.4 Hz,and the frequency domain is wider than the former.关键词
