An example of abnormal interference of geoelectric resistivity observation

In this paper, based on the operation flow of the anomaly verification standard of electromagnetic subject, the anomaly verification of geoelectric resistivity anomaly events at Anqing Seismic Station is investigated using the principles and methods of electromagnetism. Combining with the characteristics of abnormal changes in data, the focus of investigation is carried out to identify interference sources, eliminate interference and restore normal data. Verification of anomaly of observation data is an important way to distinguish precursor anomaly and disturbance anomaly. The determination of the nature of anomaly data is of great significance to the study and judgment of earthquake situation.
