摘要: 本文讨论了鲜水河活动断裂带炉霍段的水平断错、古地震遗迹与地震重复间隔等问题。晚更新世以来断裂的平均滑动速率为13毫米/年。全新世中期以来大震的重复间隔时间小于600年。

Abstract: The horizontal displacement, pre-historical earthquake traces and earthquake recurrent interval along Luhuo segment of the Xianshuihe active fault zone are discussed in this paper, The average slip rate of the fault since late Pleistocene is 13mm/a. The recurrent interval of large earhquakes since Mid-Holocene is less than 600 years.

Key words: Xianshuihe fault, Luhuo segment, Horizontal displacement, Recurrent interval, Slip rate
