摘　　要：本文分析了1975年海城7.3级、2008年汶川8.0级和2004年印尼苏门答腊9.0级地震与地球自转的关系,给出了震前震中附近地区中小地震与地球自转之间较好的相关关系。结果对深入认识地球自转与地震发生之间的关系具有裨益。This paper investigated the relationships between Earth rotation and the 1975 M7.3 Haicheng,Liaoning earthquake,the 2008 M8.0 Wenchuan,Sichuan earthquake and the 2004 M9 Sumatra earthuqke along with the small to moderate earthquakes occurring around their epicenter regions prio to the occurrence of the strong earthquakes.The obtained results could benefit to the further understanding of the problem about the relationship between the earth rotation and earthquakes.
