Abstract

Abstract

The Tanlu fault zone is an important active fault zone in east China. Many great earthquakes have occurred along it. The 1668 M8.5 Tancheng earthquake is the largest recorded event. With the constraint of surface rupture, we get a coseismic rupture model based on the elastic dislocation theory. In addition, we calculate the coseismic, postseismic deformation and Coulomb stress change of this earthquake with a viscoelastic multilayered model. The results show that the rupture fault of the earthquake is adextral strike-slip fault, which has slight thrust. The coseismic displacement of this event is very large. The accumulated energy is released thoroughly. The coseismic rupture of the 1668 Tancheng earthquake increased the Coulomb stress on the northwest, northeast and southeast faults of Tanlu fault zone. The Coulomb stress increases further due to the postseismic deformation. After 350 years of the Tancheng earthquake, the Coulomb stress changes in Shanxian, Suqian and Rizhaoget to +1bar-+1MPa. When the mantle is imposed different viscosities, the duration time which the deformation and Coulomb changes become stable will be different. However, the stable values of them are generally same.
