| Abstract: | The period of historic earthquakes and the characteristic of current earthquake activity in North China area are studied. Through analysis on the characteristic of seismic activity on different belts in North China area in different seismic act we conclude that, North China area is in a modulating stage of fourth active period. It will enter a new seismic active act in a few years, which is active mainly in Yan-Bo belt and east Shandong- south Yellow Sea area with 5-6 magnitude. |
