摘要
运用非均匀介质中“非线性振动的局域能量聚集”过程,模拟唐山78级和大同61级地震的前兆场演化,发现地震孕育过程中出现的诸多前兆特征与地壳内构造能量的非线性聚集有关。
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.
