摘要
系统地整理和分析了河北省有史以来4级以上的地震序列类型,并结合该地区地震地质构造特征进行研究。结果表明:①河北省地震序列类型以主余型为主,孤立型地震次之;②地震序列类型在空间分布上也有着较为明显的区域特征;③河北省有记载以来M≥4.0地震共计328次,其中有287次地震可确定地震类型,结合区域构造特征,可以将河北省划分为7个不同的地震类型分区,为震后河北省地震序列早期趋势判定提供重要参考依据。
This paper systematically analyzes the types of M≥4.0 earthquake sequences in the history of Hebei province combining with earthquake geological structure.The results show:(1)The M≥4.0 earthquake sequences in Hebei province are mainly mainshock-aftershock type followed by isolated type.(2)The types of earthquake sequences also have obvious characteristics in spatial distribution.(3)There have been a total of 328 M≥4.0 earthquake sequences recorded in Hebei province,among which 287 earthquake sequences can be determined.Combining with regional structural characteristics,Hebei province can be divided into 7 different earthquake sequence type zones.Our study may provide an important reference for determining the early trend of earthquake sequence in Hebei province.
