近200年来全球地震活动与月相及地球自公转的关系分析

对1811-2008年近200年来全球地震活动与月相、日地距离、地球自转速度这三个天文因素的统计分析表明，月相不论与全球地震还是全球大地震之间似乎无统计关系，全球地震的发生与日地距离似乎无统计关系。本文还进一步对全球M≥7．5的大地震进行了统计，结果表明M≥7．5的大地震与地球处于近日点似乎有一定的关系，但关系不太明显。全球除了8．0〉M≥7．0的地震基本上符合发震的自然概率外，在M≥9．0、9．0〉M≥8．0、6．0〉M≥5．0、4．0〉M≥3．0这些震级段地震发生的机率在地球自转减速期比较小，在地球自转加速期发生的机率比较大，似乎地球自转速度的变化对全球地震活动有一定的促发作用，但不明显。

EFFECT OF ASTRONOMICAL FACTORS ON GLOBAL EARTHQUAKES IN 200 YEARS

The correlations among the lunar phase, the solar - terrestrial distance, the earth rotation and earthquakes in the whole world are analyzed. The results show that there is no relationship between the lunar phase, the solar - terrestrial distance and occurrence of earthquakes. The paper also analyzes the earthquakes （M≥7.5）, and the results show that the earth is located in perihelion is probably a reason of triggering of earthquakes （M≥7.5）, but the relation is not clear. Except for the global earthquakes （8.0 〉M≥7.0） are basically meeted the seismic shock of natural probability. The probability of occurrence of earthquakes （M≥ 9. 0,9. 0 〉 M ≥ 8.0,6.0 〉 M ≥ 5.0 and 4. 0 〉 M ≥ 3.0 ） are small when the earth rotation slow down, the probability is big when the earth rotation accelerate, but it is not clear. It seems that earth rotation variation effect on earthquakes. As far as global average, the probability of occurrence of global earthquakes is small when the earth rotation slow down, the probability is big when the earth rotation accelerate, but it is not clear.
