The results show that the shear stress between two blocks of the fault is decreased rapidly and the vertical fault throw is obviously increased at the fracture segments where there is underground hot water action. With the vertical fault throw increasing, the shear stress transfers to two ends of the fault at the place where there is no underground hot water action, and the earthquake probably develops at these two ends of the fault.展开更多
