摘要
从大地构造、地壳结构与地震区域断裂带的特殊性角度阐述本区发震构造的背景。对三江断裂带地震活动时空分布特点和地震发生带的规律进行分析研究。从复杂的地震地质环境中分析了解云南地区地震活动频发原因。
This paper interprets the geological setting of the earthquake origin structure in the three-river structural zone according to the characteristics of geotectonics, crust structure and regional seismic fault belt. The features of time-space distribution of seismism in the three-river fault zone and the law of earthquake origin area are analyzed and studied. And the cause of frequent seismism in the complicated seismic geological environment of Yunnan is discussed.
