Adopting double-difference location approach method, small earthquakes in X region and its surrounding area of 1830 M7 are relocated and intensive belt are found out. According to spatial distribution characters of the belt, relationship between the belt and active geological fault are studied. The result shows that small earthquakes are mostly concentrated upon junction area of faults in NE trending and Cixian-Daming fault.
