特殊天象组合期与地震发震关系的检验及应用

本文分析了1951—1980年内全球≥7级地震、中国≥6级地震发震时刻与特殊天象组合期的关系。分析结果得到:就全球大地震来说,组合期的意义不大,但对中国≥6级地震来说,则有一定意义。组合期内发生地震的可能性平均比平常要大1.12倍,特别是华北地区大达2.25倍。发现太阳活动强弱对于地震发震的调制作用是比较明显的。 据30年的检验,认为天象组合期及太阳活动性对于中国地震,特别是华北地震有一定的触发作用。今后应继续发布每年的“组合期”及太阳活动程度,以供地震部门使用。

EXAMINATION AND APPLICATION OF THE RELATION BETWEEN SPECIAL CELESTIAL PHENOMENON COMBINATION PERIOD AND EARTHQUAKE OCCURRENCE

This paper analyzed the relation of the occurrence time of earthquakes M>>>>>>7 all over the world and M>>>>>>6 in China from 1951 to 1980 and the special celestial phenomenon combination period. The analytical results show that such a combination period does not have obvious regularity, -but it is of a certain significance for earthquakes M>>>>>>6 in China. The possibility of the occurrence of earthquakes in the combination period is 1.12 times greater than the usual, especially in North China; it is 2.25 times greater. It is found that the solar activity condition has clearer modulation role on the earthquake occurrence. According to 30 year's examination, it is thought that the celestial phenomenon combination period and the solar activity have cer-tian triggering action on earthquakes in China, especially in North China. In future, the "combination period" of every year and the solar activity degree should be published continuously for application of the seismological system can use.
