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。
This article discusses a tectonic activity of the continental-type shallow earthquakes. The analysis of six major earthquakes shows that the large earthquake sequence has a conjugate bifacial rupture surface. The rupture surface development in both directions is generally different. This depends mainly on the heterogeneity of the media in the earthquake zone. In connection with some similar phenomena before large earthquakes, it is pointed out that the study of the conjugate tectonic activity before and after the major earthquakes has certain significance for the prediction of major earthquakes and strong aftershocks.
