Abstract Hebei Province is one of the major areas where strong earthquakes occur in China, and the study of seismic structures in this area is of great significance to the understanding of earthquake disasters. Based on the 1:200 000 regional gravity and 1:200 000~1:50 000 aeromagnetic data, the fault system in Hebei Province is systematically studied by using the wavelet multi-scale fault analysis method, and applied to seismological structure analysis. The characteristics of the seismogenic faults of the 1966 Xingtai M7.2,1976 Tangshan M7.8 and 1679 Sanhe—Pinggu M8 earthquake are emphatically analyzed. It is found that the shallow faults of Xinhe fault, Tangshan fault and Xiadian fault are closely related to the deep faults. The plane position of shallow faults overlapped with the deep faults of the Xingtai M7.2 earthquake. The Xingtai M7.2 earthquake is the result of the joint action of the lower deep faults and the shallow Xinhe fault. It is concluded that the processing and interpretation of gravity and aeromagnetic data is an effective, fast and economical method for studying seismogeological structures, which can provide important information for the study of Seismogeological structures.
