摘要
从震源机制和动力学参数方面讨论了北部湾地震的震源应力场，结果表明，主震是在北东东向构造的作用下发生的；同时计算了动力学参数如破裂长度、地震矩、应力降、破裂面积和平均位错等，并探讨了非线性地震与较大余震的关系。
The focal stress field of the Beibuwan earthquake has been studied with the focal mechanism and dynamic parameters.The result shows that the main shock occurred under by NEE direction tectonic activing.The dynamic parameters,such as rupture length,earthquake moment,stness drop,rupture area and average dislocation,have been calculated;and the relation between nonlinear earthquake and larger aftershocks has been approached too.
