摘要
利用三峡及邻区发生的 4 0多次历史地震资料 ,结合 30多年来的 2 0多次地震灾害现场考察资料 ,对三峡地区地震灾害损失进行了预测。结果显示 :同震级的水库诱发地震的危害性比天然构造地震大 ,破坏性更强 。
Using the data of over 40 historical earthquakes in the Three Gorges and adjacent area and together with the investigation data of over 20 seismic disasters in the past over 30 years we have made a prediction of the probable loss of seismic disaster in future.The results indicate that the harmfulness from a reservoir-induced earthquake is stronger than that from a tectonic quake of the same magmitude,but will not endanger the dam in the Three Gorges.
