本文从强震的地质背景——发震构造特征和破裂性质——出发,以我国西南地区为例,分析了强震的时空分布图象与地质构造的关系及强震序列的多种现象,将强震分为A、B两种地震地质类型。A型:是继承性破裂,发震构造是强烈活动的深大断裂,地震能量集中释放;多为主-余震型序列。B型:是新生性破裂,多发生在断块内部的多组构造交织地区,地震能量分散释放,多为强震群序列。
Based on the geological background of strong earthquakes, the tectonic characteristics and rupture characteristics of seismogenic faults, taking the southwest of China as an example, the relationship between strong-earth spatiotemporal distribution images and geological structure and many phenomena of strong earthquake sequences are analyzed. The strong earthquake is divided into A, B two types of seismic geology. Type A: is a succession of ruptures, seismogenic structure is a strong activity of deep faults, the release of seismic energy concentrated; mostly dominated - aftershock-type sequence. Type B is a neoclassical rupture that occurs mostly in multiple groups of intertwined areas within the fault block. The seismic energy is dispersed and released, mostly in the order of strong earthquake swarms.
