摘要

通过分析山西代县中小地震与晋冀蒙交界地区中强地震活动的相互联系,发现几次中强地震前3~1 a,山西代县地区均出现过小震增强活动异常,该地区可能是晋冀蒙交界地区中强地震前的应力调整窗口。分析表明,岱海断陷带和山西断陷带的形成和演化有着相同的机制,具有统一的动力学特点。
Through the analysis on the relation between small earthquake activities at Daixian,Shanxi and medium-strong earthquake activities in the crossed area of Shanxi,Hebei and Inner Mongolia,it is found that anomaly of strengthening of small earthquake activities always appeared in Daixian,Shanxi before 3～1 years of several medium-strong earthquakes.It is thought that this area is probably the stress adjustment window before earthquakes of the crossed area of Shanxi,Hebei and Inner Mongolia.The analysis shows that the formation and evolution of Daihai down-faulted belt and Shanxi down-faulted belt have the same mechanism and dynamical characteristics.
