【摘要】 本研究利用首都圈及邻近地区有史以来Ms≥31/2历史及现代地震目录,开展Ms≥4地震序列类型判定,结合地震序列类型分布特征和构造分布特征尤其是地震带分段成果,将研究区划分出阳曲—代县、繁峙—怀安、尚义—延庆、三河—涞水、献县—武清、宝坻一青龙、渤海等7个震型分区,为首都圈地区震后趋势判定提供参考依据,在利用历史有感地震开展地震序列类型和利用地震带分段开展震型分区研究方面进行了有益探索.更多还原

【Abstract】 We judge the M_S≥5 4 earthquake sequence types using the historical and modern M_S≥3(1/2) earthquake catalogue and divide the research area into seven shock type partitions:Yangqu-Daixian,Fanshi-Huai’an,Shangyi-Yanqing、SanheLaishui、Xianxian-Wuqing、Baodi-Qinglong and Bohai,combined with distribution characteristics of earthquake sequence type and structure,especially the seismic belt segmentation result.This work provide a reference for the tendency judgment after shock in the capital area.We also do some beneficial discussion in the research of earthquake sequence types using historical felt earthquakes and earthquake type partition using seismic belt segmentation.更多还原
