On December 18, 2023, an M_S6.2 earthquake occurred in Jishishan County, Gansu Province. This study selected four geoelectric field observation stations within 300 km of the epicenter. On the basis of a wavelet transform to extract dominant frequency components at each station, we applied a sliding correlation method to statistically analyze anomalous correlationsbetween these components and seismic events within 400 km. Additionally, a retrospective test was conducted using changes in the dominant azimuth of the geoelectric field over 60 days before and after the Jishishan earthquake. The results show that (1) the sliding correlation results from Wuwei, Menyuan, and Dawu stations showed higher correlations among seismic sequences with higher energy and long-period geoelectric components (24 h, 12 h), whereas sequences with lower energy exhibited stronger correlations with short-period components (8 h, 6 h). (2) The occurrence time of anomalies in the dominant azimuth of low-frequency geoelectric components(24 h, 12 h) before the Jishishan earthquake aligned well with the results of sliding correlation statistics, suggesting potential coupling among solid Earth tidal cycles and seismogenic fault interactions. (3) Variations in statistical results and dominant azimuths across stations may arise from differences in epicentral distances or geoelectric signal propagation paths.
