三峡水库蓄水前后三峡库区地震监测简介
|
摘要
介绍了三峡地震监测系统的组成、监测范围以及对三峡工程运行所起的重要作用,通过三峡工程蓄水前后,三峡地震监测系统在库首至库中地区记录到地震的震中位置、强度和频次等的对比。归纳了三峡工程蓄水后,库区水库诱发地震的基本特点,指出目前三峡水库蓄水后库区的水库地震基本处于工程前期预测范围之内,无破坏性地震发生。
The paper briefly introduces the composition of earthquake monitoring system of the Three Gorges area, earthquake monitoring range and the important action of the Three Gorges Project operation. Before and after the impoundment of the Three Gorges Reservoir, the monitoring system had recorded a lot of earthquake data in the upper area and middle area of the Three Gorges. On the basis of the comparison of epicenter location, magnitude and frequency numbers about the recorded earthquake, it briefly induces the basic characters of reservoir induced earthquakes after the impoundment of the Three Gorges Reservoir, and also points out that the reservoir induced earthquakes which have occurred after the impoundment of reservoir were essentially within the range of former prediction. There was no destructive earthquake occurrence after the impoundment of the reservoir areas.
