河北中强地震序列类型统计及空间分布特征

Statistical and Spatial Distribution Characteristics of Moderate and Strong Earthquakes Sequences in Hebei Province

  • 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。

     

    Abstract: 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.
