| Abstract: | The evolution process of precursory fields for the Tangshan earthquake with M7 8 and the Datong earthquake with M6 1 was simulated by using of the process of regional energy concentration for the nonlinear vibration in inhomogeneous media. The results show that the various precursory features observed during the seismogenic process would be related with the nonlinear concentration of energy in the crust. |
