备注

采用概率预测方法,依据设计参数对糯扎渡水电站水库蓄水后诱发地震的可能性进行了判断,同时对可能的最大诱震震级进行了计算,得出糯扎渡水电站水库蓄水后将发生水库诱发地震,可能的最大震级为5.5级。

We use probability prediction method to analyze the probability of earthquake induced by Nuozhadu Reservoir and calculate the maximum induced magnitude based on design parameters of the reservoir.After Nuozhadu Reservoir stores water,it will be capable to induce the earthquake with the maximum magnitude of 5.5.
