【摘要】 通过对海城Ms7 3地震震源机制、余震分布和Ms5 6地震震源位置变化的分析认为 ,海城Ms7 3地震震后产生的Coulomb静应力变化可能是这次地震的主要力源 ,并结合震区地壳的地球物理性质和这次地震序列的时空分布特征 ,对这次地震的发震过程和邻近地区的地震形势做了讨论。更多还原

【Abstract】 By means of analyzing focal mechanism and aftershock distribution of Hai cheng M S7 3 earthquake,and source position of M S5 6 earthquake,The authors hold that the Coulomb static stress change Δ CFS induced by Haicheng M S7 3 event probably is principal power of the M S5 6 event Besides,we discussed rupture process of the M S5 6 event,and seismic tendency of adjacent area by analyzing geophysical characters of crust medium,and time space characters of M S5 6 event sequence更多还原
