摘要

    

In this paper, characteristics of seismic activity in juncture area of Shanxi, Hebei provinces and Inner Mongolia are analyzed, the results show that since 1929, earthquakes with magnitude of M_S≥6.0 in the area are mainly in the Hetao seismic belt and Zhangjiakou — Bohai seismic belt, at latitude 40 degrees and the surrounding area forms a dominant distribution area. Since 1970, the medium earthquakes are mainly distributed in a triangle region formed by Helinge’er of Inner Mongolia, Datong of Shanxi Province and Zhangbei of Hebei Province. A great deal evidences show that Shanxi, Hebei and Inner Mongolia triangle area as well as huhetaote—baotou fault are favorable zone of earthquake, the seismic intensity may be M_S6.0.
