摘要
峪道河断裂为交城断裂汾阳段的分支断裂,通常认为其最新活动时代为中更新世,文章在查阅相关地质、地震活动性资料和野外调查的基础上,判定峪道河断裂最新活动时代为晚更新世,并根据经验公式,指出其存在发生6.5级地震的危险。
The age of the latest activity of Yudaohe fault,a branch the Fenyang segment of Jiaocheng fault,is generally considered in the Middle Pleistocene.Based on the geological and seismic activity data,and field survey,the author concludes that the age of latest activity of Yudaohe fault should be in the Late Pleistocene.Also,the risk of the occurrence of a 6.5 earthquake by Yudaohe fault is evaluated according to an empirical formula.
