Abstract：Regarding the synchronous decline in the two sets of geo-resistivity observation systems at Nanjing station on January 9,2023,we checked the condition of the observation system,investigated the natural and site environmental factors,as well as conducted multi-scale and multi-item joint analysis in time and space.The results show that this anomaly is affected by the construction of high-voltage transmission lines rather than earthquake precursor anomaly,and the explanation was provided for the abnormal mechanism.The process of analysis and determination of interference has a great reference value for verifying the causes of abnormal changes in geo-resistivity data,and also provides a train of thought for the analysis and interpretation of geo-resistivity abnormal data.
