Abstract
North China region(37°-41.5°N,112°-120°E)is divide into 130 zones(50km×50km).All the earthquakes occurred in recent ten years in the 130 zones are studied by statistics.The seismicity in each zone is analyzed from the temporal and spatial distribution,and the zones that have the same character are categorised into one type.Based on the crustal deformation background in each zone,the earthquake activity is predicted.
