| Abstract: | The main conclusions of the study on the seismicity tendency by other men of learning are reviewed briefly, and the main behaviors of the seismicity in time and space are obtained.Meanwhile, the tendency of seismicity in northern Qinghai Tibet plateau is analyzed systematically. There are 6 active periods and 6 quiet periods of seismicity in the region in the 20th centenary, not synchronizing with that of the continent of China. A new active period for earthquake begins by the Jingtai M S5.9 earthquake on June 6, 2000 and the Xinghai M S6.6 earthquake on Sept.12,2000. |
