| 摘 要： | 依据地震破裂、地震形变带、前震和余震分布,对中国大陆共轭破裂强震进行了初步研究。结果表明,强震共轭破裂现象较普遍,据资料至少有12个单强震、7个双主震和2个主震——强余震为共轭破裂强震。其共轭破裂特征在地震形变带展布、烈度等震线形态、前震和余震分布等方面表现明显。另外,共轭破裂强震具有共轭破裂面方位之一多为北北西向、双主震之间和主——强余震之间相隔时间为“7”和“9”的节律这2个主要的共同点。

| Abstract: | In this paper, a primary study was made on strong shocks with conjugate rupture by research for earthquake faults, deformation belts, foreshock and aftershock distributions in Chinese continent. The results indicated'that the conjugate rupture of strong earthquakes is a common phenomenon. There at least 12 strong single earthquakes, 7 main double earthquakes as well as 2 main earthquakes with the strongest aftershocks belong to conjugate ones. Their characteristics are shown clearly on the seismic deformation belts, isoseismal shapes, foreshocks and aftershocks distributions. Furthermore, two main common features were found in this kind of strong shocks sequence. In detail, most of the conjugate rupture faces are NNW, and the interval times between the main double earthquakes and the main earthquakes with strongest aftershocks are in rhythm of "7" and "9". |
