| 摘 要： | 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

ON THE SEISMO GEOLOGICAL TYPES OF STRONG EARTHQUAKES IN SICHUAN AND YUNNAN PROVINCES |

| Abstract: | Starting from the analysis of geological background, tectonic features and fracture properties for strong earthquakes, as well as taking the earthquakes in sichuan and Yunnan as examples, we studied the relation between the temporal and spatial distribution patterns and the tectonics for strong shocks. As a result, the stromg esrthquakes were divided into two, A and B, seismogeological types. For type A, the earthquake is due to a continuing fracture. The earthquake-generating structure is a dee |
