| Abstract: | Based on the observation data of ground resistivity at Wujiahe Seismic Station from 2015 to 2018, the abnormal changes of the data are analyzed. Combined with the observation environment and field investigation, the factors affecting rainfall, thunder and lightning, metal pipelines, farmland irrigation and equipment leakage are found. The characteristics of various interference curves, variation range, influence time and interference frequency are analyzed and summarized in order to correctly recognize and eliminate them. Ground resistivity interference is helpful for identifying seismic anomaly information. |
