Abstract In this paper, based on the tidal wave of the telluric field, we establish a model of the seepage(movement) of the rock crack water(charge) seepage, and calculate the dominant azimuth angle α of the telluric field in Liaoning area. We make a comparative analysis on the degree of change of the dominant azimuth angle α of the telluric field that we combined with typical disturbances such as rainfall, temperature, and magnetic storms. The results show that the dominant azimuth α of the telluric field is limited by typical interference. Combined with the dynamic change of the dominant azimuth α before and after the 2013-01-23 Liaoning MS5.1 earthquake, we find that the long-term sudden change of the charge movement direction of the rock mass fissures of the same or adjacent geological structure geoelectric field stations can be considered as the precursory anomaly of a moderately strong earthquake.
