震源应力场、形变场和倾斜场

本文从水平构造应力作用观点出发,研究了各类震源的应力场、形变场和倾斜场,推导了由垂直形变资料估计地震矩和震级公式.结果与实际观测资料比较符合.最后对强震发生的地震地质条件和弹性回跳理论的正确性和普遍性问题进行了讨论. 

STRESS DEFORMATION AND TILT FIELDS OF THE EARTHQUAKE SOURCES

In this paper, from the point of view of the action of horizontal tectonic stress, the author has investigated the stress, deformation and tilt fields of the earthquake sources and derived the formulas to evaluate the seismic moment and magnitude from the vertical deformation data. The results agree with the observational data rather well.Finally, the seismo-tectonic condition for the occurrence of strong earthquakes and the credibility and generality of the elastic rebound theory has also been discussed.
