The rheological model was jointly completed by Shao Zhigang, Institute of Earthquake forecasting, China Earthquake Administration, and Xu Jing, the Second Monitoring Center.The team established a model of crust-mantle viscous structure in the China  Seismic Experimental Site, and obtained preliminary results of the distribution of viscosity coefficients at different depths (20km, 40km, 60km, 80km) and profiles of viscosity coefficients across different locations in the eastern boundary zone of the Sichuan-Yunnan diamond block As a result, it provides a rheological structure reference for the construction of regional kinematics model and dynamics model.
