加速异常主要集中在孕震区的调整单元或断层活动地段。
The acceleration anomalies are mainly concentrated in adjusting unit in earthquake generating area or active segment of the fault.
根据含超压气体裂隙震源模式，分析了地球内部放射热能向孕震区积聚的过程。
By using the seismic source model of crack containing hyperpressure gas, the course of radioactive heat energy in the earth to accumulate in the focal area and cause for earthquake are studied.
分析认为，孕震应力场的应力强度对孕震区内地震的破裂方向有明显的约束作用。
This suggests that focal stress intensity has restraining effect on earthquake's rupture direction.
