Analysis of interference factors of extensometer observations at Ulanhot Seismic Monitoring Center Station
Based on the extensometer data from 2015 to 2022 at Ulanhot Seismic Monitoring Center Station,the interference factors of the natural environment,human factors,and site environment on the observation data are analyzed,in which the interference characteristics are mainly manifested as missing records,data jumps,steps,rough curves,increased burrs,solid tide distortion,and so on.The research results can provide a reference for the interference identification of extensometer observation data and the analysis of earthquake anomaly characteristics.
