摘要
对华东地区1970年以来5级以上地震的月相效应进行了分析,表明该区地震活动具有明显的月相效应;分别对华东、安徽地区1970年以来4.5级和4级以上地震的月相调制比进行分析研究,认为华东Ms5.5级、安徽Ms5.5级以上地震活动受月相调制作用显著,分别提出了华东地区Ms≥5.5级及安徽地区Ms≥5.0级地震发生前月相调制比的定量预测指标,它对这两个区域大震的发生具有中、短期预测意义。
The lunar phases since 1970 about Ms5.0 of the east of China are analyzed. The result indicates that earthquake activities correspond with the lunar phases. Since 1970, earthquakes of Ms4.5 and Ms 4.0 and lunar Phases are closely related. We can advance the standards of ratio forecasts of the Ms≥5.5 in East China and Ms≥5.0 in Anhui Province. This standard has some medinm-or-short time significance in forecasting big earthquakes in the two areas.
