Abstract

Abstract: An M_S5.5 earthquake occurred in Aksai County， Jiuquan on August 26， 2021. Based on the 2020—2021 observation data of 6 geoelectric field observation stations within a range of 500 km from the epicenter， a geoelectric field rock fissure water (charge) seepage (movement) model was used to calculate the dominant azimuth angle of the geoelectric field observation station. Combined with the focal mechanism and fixedpoint deformation observation data at Anxi station， we concluded that: ① The dominant azimuth angles showed abnormal changes at Shandan， Gaotai, Baishui River， which started in May 2021 and showed a certain degree of synchronicity. There was no significant abnormal change in the dominant azimuth angles at Guazhou， Dulan， and Jiayuguan. ② The daily average values of the Anxi Station's extensometer， vertical pendulum， comparing with Guazhou Station's geoelectric field that were approximately 12 km apart， showed nearly synchronous trend changes， acceleration， jumps， and other abnormal changes from April to July 2021， which indicated the correlation between different physical parameters. The application of geoelectric field and fixed point deformation observation data， through comprehensive analysis and mutual confirmation， we determined the changes in regional stress state， which provide ideas for exploring the application of different physical parameter anomaly evolution in data reliability analysis and earthquake prediction.
