【Abstract】 Why a strong earthquake occurs in a specific region? It might be concerned in the specific structures in this area. The preliminary studies are made on the seismo-structure and the related problems in this paper, based on the geological results of the coal field and the geodetic data in the Tangshan epicentral region.It is suggested that the occurrence of the Tangshan earthquake related to both the evolution of the asymmetric Kaiping syncline and its recent activities. The seismic fault is resulted from the evolution of the inverted slope of the syncline that subjected to the continuous pressure and shear. The seismic fault is linked up with the deep fault in the form of arc(listric model).The research on the specific characteristics of the seismo-structure is helpful to deepening the study of seismogeology.更多还原
