From 2017 to 2019,four moderate strong earthquakes occurred in the Songyuan area which is the most concerned earthquake hazard region in Northeast China. During that period,the apparent resistivity observation from Suihua station,about 220km away from Songyuan area,recorded some abnormal changes. To analyze the relationship between the anomalies and these moderate earthquakes,the sensitivity coefficient of medium in the survey area is calculated by using the three-layer horizontal layered model. It is found that the anti-annual variation of the apparent resistivity is related to the Q-type electrical structure of the survey area. Then,taking the focal mechanism of the 2018 Songyuan M_S5.7 earthquake as an example,we used the fault virtual dislocation model to calculate the deformation characteristics of the medium in Songyuan area. We found that Suihua station was located in the area of compressive deformation enhancement before the earthquake,and the decrease and return changes of the N15°E and N75°W observations are consistent with the change form of stress accumulation release. Finally,based on GPS data,there is no significant anomaly found in the apparent resistivity at west of Suihua station,which may be due to the decrease of the main compressive strain rate from east to west in northeast China.
