| 摘 要： | 本文从三维空间的角度,从昌马地震发生的区域构造背景和构造应力场,震源断裂和震源应力场,地震的动力来源,震源介质条件、震源闭锁形式和地震发震机制等方面探讨了昌马地震的成因,提出了“三维空间四方受压的震源闭锁模式和“倒楔型”劈裂的发震机制。

| Abstract: | The genesis of Changma earthquake has been studied in three dimentional space in the paper,including the regional tectonic background and tectonic stress field,the focal fault and stress field,the earthquake force resource,medium condition in and near focus,the source locked model of the earthquake and the seismooccurring mechanism.The author puts forward the source locked model from four direction compression in three dimensional space and the seismooccurring mechanism caused by reserved wedge splitting on the earthquake with Ms=7.5. |
