Abstract：The present activity characteristics of main faults in Liaoning area are analyzed using cross-fault data. The results of long-term data show that the activities of Yalujiang and Hunhe faults in northeastern Liaoning are relatively stable, and the activities of Jinzhou fault in southern Liaoning and Chaoyang-Beipiao and Dalinghe faults in western Liaoning are relatively active. There is a certain similarity between Jinzhou fault and Chaoyang-Beipiao fault. The 2011 M9.0 earthquake in Japan had a significant impact on the activities of Jinzhou and Chaoyang-Beipiao faults. Since 2015, the activity level of Jinzhou and Chaoyang-Beipiao faults is consistent with its background level and is at a weak activity level.
