摘要
龙滩水库2006年10月蓄水以来,库区地震活动频繁,这可能是原有构造地震的进一步活动,也可能是水库诱发地震。因此,有必要对龙滩水库蓄水后发生的地震性质进行判断。本文根据国内外已发生水库诱发地震震例资料和以往经验,结合龙滩库区具体情况,利用定性判断法和概率统计法对龙滩库区地震性质进行验证和判断,结果认为:龙滩库区蓄水后发生的地震属诱发地震。
After Longtan Reservoir retained water, seismic activities became frequent in the reservoir area. It may be further activities of the tectonic earthquake, or it may be induced-earthquake by reservoir. It is necessary to analyze the nature of earthquake. In this paper, basing on do- mestic and abroad reservoir-induced earthquake information and past experience, and com- bined with the specific circumstances, the nature of earthquakes in Longtan Reservoir area were verified as reservoir-induced earthquake.
