【摘要】 三峡巴东库段及邻区的地震活动在时间、空间和强度上的变化主要是由水库蓄水引起的。经对地震基础资料及波形特征的分析后认为:区内地震活动可分为天然构造地震和非构造地震两种成因类型,其中后者包括溶洞塌陷地震、矿洞塌陷地震和山体崩滑地震等。更多还原

【Abstract】 In Badong alongshore zone of the Three Gorges reservoir and its adjacent regions,the changes of seismicity and strength are caused by the impoundment of the Three Gorges reservoir.According to the basic seismic data and characteristic of wave,the earthquakes in this area can be distinguished into tectonic earthquake and atectonic earthquake.The latter includes karst collapse,mining collapse and hill collapse and all of them are caused by water action of reservoir i.e.they are reservoir-induced earthquake.更多还原
