摘要

晋获断裂带是华北地震区中一个次级构造单元,也是地震活动中的一个地震活动亚带。从分析该带的构造特征和地震活动特点出发,分析该带的分段性,发现变形强度由北向南递减、构造层次由北向南抬高。结合历史地震活动和现今地震活动,得出该带北段是该地震亚带主要的地震活动场所。在此基础上,由震级-时间模型对未来北段的强震活动进行预测。
Jinhuo fault zone is a sub-structural unit of the earthquake zone in North China and a sub-band of seismic activity.According to analysis of structural characteristics and seismic activity characteristics,the belt partition of the Jinhuo fault zone is studied.The result shows that deformation intensity decreases from north to south,structural level improves form north to south.Historical seismic activity and present seismic activity indicate that the northern section is the main sites of seismic activity to the sub-band of seismic activity.On this basis,the predication of seismic activity of strong earthquakes in northern section is carried out using magnitude-time model.
