摘要
中国西部及周邻地区大震活动与地球自转速率变化有一定关系,尤其是8级以上特大地震与地球自转变化的加速期关系更为密切。中国西部及其邻区76％的地震发生在地球自转速率变化的相对加速期。本文通过地震活动与地球自转变化的关系,对帕米尔-杭爱山地区本世纪末至二十一世纪初的地震危险性作了趋势性估计。
It is found out that there existed the certain correlation of the seismic activity with the rate of the earth rotation. The most obviously one was that during the accelerating period of the earth rotation, there often occurred the maximum earthquakes (M≥8. 0), for example, 76 percent of the large earthquakes along the west of China happened during the relative accelerating period of the earth rotation. Based on this characteristics, the author made a trend analysis on the seismic risk region along the Pamir -Hangai area for the time both of the end of this century and the next one.
