Abstract: The correlations between large earthquakes in China continent and periodicities of the Moon's movement and the solar activity are statistically analysed and the following points are revealed:1. The earthquakes with ≥7.5 in Qing-Zang fault-block region have 18.6-yr periodicity of the Moon's nodes motion.2. The earthquakes with M≥7.1 in Xinjiang fault-block region have 8.85-yr periodicity of the Moon's perigee motion.3. The earthquakes with M≥7.0 in China mainland have the tendency to cluster around times of minima of sunspot cycles and in the even solar cycles.4. The earthquakes with M≥8.0 in China continent have the tendency to cluster around the valley times of the secular cycles of the solar activity.According to above correlations,the prediction of seismicity tendency can be given as follows: In China continent,especially Western China,the current active seismic period should continue up to the end of this century. The next active period would be 2006—2015.
