长江三峡地区地震活动度分析

ANALYSIS ABOUT DEGREE OF SEISMICITY ATTHE AREA OF THREE GORGE ON THEYANGTZE RIVER

本文运用地震活动度的概念,对三峡地区地震活动特征及其与地质构造的关系进行了分析,得出了本地区地震活动度年平均值低,Ms≥2.0级地震与构造有密切关系等结论。

In this paper, the relations between seismicity characteristics and the geological structure at the area of Three Gorge are analysed by applying the concept of degree of seismicity. The result shows that the mean value of degree of seismicity at this area is very low and the earthquakes of Ms≥2 bear close relations to the structure.
