Spherical Discontinuous Deformation Analysis Method on Movement Numerical Simulation Forecast of Jiashi Earthquake Area

Considering the movement character of discontinuous deformation in Jiashi strong earthquake swarm,the stress and distance fields of fore-and-aft earthquake are systemically studied using the spherical discontinuous deformation analysis method with the restriction condition of GPS observations.Through the second distance restriction,the process of the pregnant,happening and the congregation again of earthquake are numerical simulated,and the earthquake movement law in Jiashi area is opened out.
