摘　　要：根据显著地震地方平太阴时分布预报地震的思路,对台湾地区1971年以来14组MS 7级以上地震前显著地震特征进行了回顾性研究。研究结果显示,台湾地区14组MS 7级以上地震中,9组地震前存在两个以上显著地震,约占总地震数64%。9组存在两个显著地震中,只有1组地震前显著地震地方平太阴时夹角Δτ≥45°,其余8组地震前显著地震地方平太阴时夹角Δτ≤45°,且主震都发生在其满足条件的显著地震后29天内。结果表明,地方平太阴时夹角Δτ≤45°可应用于台湾强震前的短临预测。According on the idea of predicting earthquakes by local mean lunar times of remarkable earthquake,the characteristics of 14 groups earthquakes with MS≥7.0 in Taiwan Region since 1971 was studied retrospectively.The results showed that among 14 groups earthquakes with MS≥7,5 groups did not have more than two remarkable earthquakes before the strong earthquake,and 9 groups had more than two remarkable earthquakes before the strong earthquake,about 64%of the total earthquakes.Among the 9 groups,the local mean lunar times angle of remarkable earthquake before the earthquake was greater than 45°in only 1 group,and the local mean lunar times angle were less than 45°in other 8 groups.Meanwhile,the main earthquakes occurred within 29 days after the remarkable earthquakes.The results show that the angle of local mean lunar times less than 45°can be applied to the short-impending prediction before strong earthquake in Taiwan Region.
