Abstract：In this study ,we collected 6678 P-wave traveltimes and 6013 S-wave traveltimes in the Shanxi-Hebei-Inner-Mongolia border area .On basis of these data ,using the simultaneous inversion methods in the Velest program for hypocenter-velocity structure ,we present a 1-D minimum velocity model of the study area .With the 1-D minimum velocity model ,we relocate 1763 earthquakes in the Shanxi-Hebei-In-ner-Mongolia border area .The result shows that :the hypocenter depth is mostly between 5 km to 20 km .
