北东向的锦屏山－小金河断裂带从北东到南西斜穿整个锦屏水电站工程区。在它的东南和西北分别有北北西走向的羊坪子－纸厂沟断层组和北西走向的前波、高牛场等断层。锦屏山－小金河断裂带的马山头－周家坪断层组、瓦科断层组和北西向前波断层等晚第四纪继续活动，但活动强度很弱。工程区新构造运动以整体抬升为主，兼水平滑移和旋转运动。历史至今，工程区地震活动微弱，是地壳相对稳定的地区。 The north-east Jinping-Xiaoganhe fault zone runs through the entire Jinping hydropower station from north east to southwest. In its southeastern and northwestern areas, there are the north-northwest strikeings of the Yaping-Zhichanggou fault zone and the NW-trending forewave and high-cattle fault respectively. The Jinshan-Xiaojianhe fault zone of the Mashan-Zhoujiaping fault group, the Waco fault group and the NW strike wave fauna continued their activities in the late Quaternary, but the activity intensity was very weak. The new tectonic movement in the project area is dominated by the whole elevation with horizontal slip and rotational movement. History so far, seismic activity in the project area is weak, the crust is relatively stable area.
