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.
Based on the history of Ms≥31 / 2 historical and modern earthquakes in the metropolitan area and its adjacent areas, this study conducts the judgment of sequence types of Ms≥4 earthquakes. Combining with the distribution features of seismic sequences and tectonic distribution, especially the results of seismic belt segmentation, The districts are divided into 7 quake-type zones of Yangqu-Dai County, Fanzhi-Huai’an, Shangyi-Yanqing, Sanhe-Huangshui, Xianxian-Wuqing, Baodi-Qinglong and Bohai Sea, This paper also provides a reference basis for the exploration, making use of historical seismics to carry out seismic sequence types and using seismic belt segments to carry out seismic subarea researches.
