| Abstract: | The evolutional process of precursory fields for the Tangshan earthquake with MS7.8 and the Datong earthquake with MS6.1 was simulated by using 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. |
| Keywords: | Seismic precursor Nonlinear evolution Energy concentration Tangshan earthquake Datong earthquake. |
