云南强震和月相、白赤交角的关系

The Relationship Between Strong Earthquakes, Lunar Phase, Inclination Between the Moons Path and the Equator at Yunnan Province

考察本世纪云南强烈地震与月相和白赤交角的关系。结果表明云南强震与月相的关系呈区带性的相关。中甸丽江带的强震大多发生在望；巧家宜良带多发生于朔和望；而大关马边带的强震则完全不发生在朔和望。另一结果显示：本世纪云南１３次７级以上的强烈地震中１１次发生在月球白赤交角的极值年及其前后２ａ（年）中，尤以勐海、耿马、峨山特别明显。

The relationship between lunar phase, inclination between the Moons path and the Equator, and strong earthquakes at Yunnan province in 20th century is presented in this paper. The result indicates that strong earthquakes in Zhongdian and Lijiang mostly occurred in Full Moon. The ones in Qiaojia and Yiliang occurred in New and Full Moon.The ones in Daguan and Mabian did not occur in New and Full Moon. Another result shows that 11 among 13 earthquakes over magnitude 7.0 at Yunnan in 20th century occurred in the extreme-value-years of inclination between the Moon s path and Equator with a radius of 2 years, especially for Gengma, Menghai and Eshan.
