Abstract: 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.

Key words: Strong earthquake, Small to moderate earthquake, Earth rotation
