We quantitatively analyzed the crustal strain changes in Xuzhou and Gaochun areas of Jiangsu province from 2019 to 2023 using four-component borehole strainmeters, and explored the characteristics of regional strain field and its relationship with seismic activity. According to the strain parameter results, both Xuzhou and Gaochun areas were in a stable state during the study period. The response values of tidal factors at Gaochun seismic station exhibited an abnormal change of first dispersion, then stabilization before and after the M5.0 earthquake in Dafeng sea area of Yancheng, Jiangsu province. Through the analysis of its variation characteristics, the relationship with the strike of faults and the focal mechanism solution of earthquakes, it can be inferred that in the process of earthquake preparation, the stress and strain in this area experienced a process from accumulation to release, and the tidal factors can reflect this change to a certain extent.
