In the paper, the feature of strong earthquake orderly distribution in time, space and intensity before the WesternKunlun Mountain Pass M=8.1 earthquake is preliminarily studied. The modulation and triggering factors such asthe earth rotation, earth tides are analyzed. The results show that: the giant earthquakes with the magnitude morethan 8 occurred about every 24 years and the earthquakes with the magnitude more than 7 about every 7 years inChinese mainland. The Western Kunlun Mountain M=8.1 earthquake exactly occurred at the expected time; Thespatial distance show approximately the same distances between each two swarms. The earth rotation, earth tide,sun tide and sun magnetic field have played a role of modulation and triggering in the intensity. At last, the condi-tions for earthquake generation and occurrence are also discussed.
