This article utilizes observational data from seven geoelectric field stations in the Shandong region starting in 2021. It determines the dominant azimuth angle α of the geoelectric field using a geoelectric rock mass fracture model. The jumping range Δα did not meet the criteria for judgment and did not meet the abnormal indicators. According to the prediction rules of this method, it is analyzed that the probability of a moderate to strong earthquake occurring in Shandong region in the near future is not high. Based on the analysis of the development of rock fractures in the site reflected by the advantageous azimuth results, the results show that the rock fractures in Heze station located on the east side of the Liaokao fault zone and Zoucheng station located between the Cangshan-Nishan fault zone and Fushan fault zone are in the generation stage, which is a common background for the development of small and medium-sized earthquakes area. The rock fractures of Anqiu station and Lingyang station located in the northern section of the Yishu fault zone and Rushan station on the east side of the Muping-Jimo fault zone are in the stage of development or growth, which is in line with the background of nurturing moderate to strong earthquakes and deserves special attention.
