摘要
通过对沐川沙湾间地质、地貌、水文地质和地震活动特征分析,认为该区3级以上地震活动与铜街子电站水库畜水有关。1993~1995年沐川西部连续发生的3次5 0级以上地震属水库诱发的构造性地震。
The seismic tectonic, landform, hydrogeology and seismicity are described in this paper. We think that the earthquakes with magnitude M3.0 are related to the reservoir operation of Tongjiezhi. The seismic tectonic activities are also due to the reservoir operation of Tongjiezhi.
