四川瀑布沟水库区域地震活动性跟踪研究

STUDY ON REGIONAL SEISMIC ACTIVITY OF PUBUGOU RESERVOIR IN SICHUAN PROVINCE

以水库诱发地震危险性指标体系为基础,构建瀑布沟水库诱发地震危险性评价表;对库区地震活动性跟踪,发现库区地震活动强度和频度没有因水库蓄、放水而出现明显的变化,综合判定瀑布沟水库发生较大诱发地震的危险性不高。

Based on the index system that the reservoir induces earthquake risk,the evaluation sheet of Pubugou reservoir induces earthquake risk has been made; for the reservoir seismicity tracking,the intensity and frequency of the reservoir seismic have been marked changes without the fact that the reservoir stores or draws off the water. The induced earthquake risk is not high by the comprehensive judge in Pubugou reservoir.
