| 摘 要： | 本文讨论的是大陆型浅源大地震的一种构造活动方式。通过对六个大震的分析表明,大震序列具有共轭的双向破裂面。两个方向的破裂面发育程度一般不同。这主要取决于震区介质的不均一性。联系一些大震前的类似现象,指出大震前后共轭性构造活动现象的研究,对主震和强余震的预测有一定的意义

THE GREAT EARTHQUAKE AND THE CONJUGATE TECTONIC MOTION |

| Abstract: | Taking six great earthquakes occurred recently in China as examples a kind of rupture mode of great continental earthquake with shallow focus is discussed. By analysing the data from ground rupture zone, the solution of the P wave initial motion, the direction of mojor axes of the isoseismal lines, the time-space distribution of aftershocks and so on, the great earthquake sequences show a characteristic of 2-way rupture with conjugate nature.The development of two conjugate rupture plane shows i |
