摘要
中条山北麓断裂是运城盆地的主控断裂.作为第四纪以来的活动断裂,其活动情况与运城盆地及周边的地震活动间存在一定的关系.采用异常参数R值法和年滑动速率比法对布设在此断裂的流动水准场地观测数据进行分析,发现2种数据分析方法结合起来能更准确地发现观测数据的异常变化,研究结果可为运城盆地及周边地区的地震预测研究提供参考.
Fault at the north piedmont of Zhongtiao Mountain is the main fault in Yuncheng basin.As active faults since Quaternary,the activity of faults is related to the seismicity of Yuncheng basin and its surrounding areas.In this paper,anomalous parameter R value method and annual slip rate ratio method are used to analyze the observation data of flow leveling sites located in this fault.It is found that the combination of the two data processing methods can more accurately detect the anomalous changes of the observed data,and provide a reference for earthquake prediction in Yuncheng basin and its surrounding areas.
