TANGSHAN EARTHQUAKE AND THE EARTHQUAKE RISK AREA |
| |
| Abstract: | In this paper considering different viewpoints of seismogenic structures of Tangshan earthquake, the seismogenic mode of Tangshan earthquake has been studied using the finite element method. The characteristics of Tangshan earthquake are also described,A preliminary discussion has been made on identifying the earthquake risk areas on the basis of both regional stress direction and condition of stress release |
