| 摘 要： | 论述2008年5月12日四川汶川Ms8.0地震和2010年4月14日青海玉树Ms7.1地震前震中附近中小地震和地球自转季节性变化的关系,介绍1970年以来中国大陆其他14例M≥7.0地震震例.研究发现,在强震前几年时间内,震中附近地区的中小地震有偏向发生于地球自转速率季节性变化加速或者减速某一阶段的现象.该结果对深入认识地震与地球自转之间的关系具有一定启示意义,对地震预测具有一定指导意义.

| Abstract: | The relationships of the seasonal variation in earth rotation with the medium-small earthquakes around the epicenter before the Ms 8.0 Sichuan Wenchuan earthquake on May 12,2008,the Ms7.1 Qinghai Yushu earthquake on April 14,2010 and the other fourteen M≥7.0 earthquakes-have been studied in this paper.From this research we find that the medium-small earthquakes in the regions of aftershocks within several years before the strong earthquakes often occur in only one period of acceleration periods and deceleration periods of the seasonal variation in earth rotation.This research will benefit for us to further understanding the relationship between earthquakes and earth rotation,and there is a certain guiding significance for earthquake prediction. |
