| Abstract: | This paper analyzes the astronomical backgrounds, such as the positons of celestial objects, variation in the earth rotation and solar activities, etc., for the recent three moderate and strong earthquakes from Chengjiang earthquake to Qiubei earthquake in Yunnan Province. The results show that all the three earthquakes occurred at the time intervals when the greater variation in the tide generating force at the epicentre appeared and the solar activities partially descended. |
