%X By analyzing the characteristics of fault-crossing displacement variation in the Capital area before and after the Ms 5.1 Wenan earthquake of Hebei on July 4,2006,and combining the characteristics of regional fault activities and regional seismicity in the area since 1970,it is concluded: 1) Since 2000 the thrust activities of NNE directional faults in the Capital area have been increasing,it shows that the present principal compressive stress in the Capital area is in NEE direction;2)The Capital area and surrounding regions may enter the next active period of medium-strong earthquakes;the Wenan earthquake marks the beginning of this period;3)The vertical activities of NE directional faults in the Capital area and surrounding areas change strongly,the amplitude of variation may be taken as an index for medium long-term earthquake prediction.
