Abstract：Based on the creep experiment, the creep curve was fitted by constitutive equation of standard linear model. In the data process of Li Yang and Nan Huanghai earthquake, there is a similarity between stain release curve and creep curve. Fitting stain release curve by standard linear model, relaxation time and other parameters are got. By calculation, crust’s viscosity is about 1018 Pa·s. Considering the regional difference and difference of layers in the lithosphere and the hypocenters in this article are relatively shallow, so the order of viscosity is con?sistent with related literatures.
