摘要
对南黄海地区 1 846年以来MS≥ 6强震活动的可公度性进行了分析 .发现该区强震活动具有 6a、1 2a和 5 7a的基本周期 ,此外还有 6 3a、6 9a和 75a的周期 .根据强震活动的可公度性特征和丛集特征 ,对南黄海地区未来MS≥ 6地震活动趋势进行了预测 ,并对预测结果进行了论证 .
Commensurable characteristics of activity of M S≥6 earthquakes in the southern Yellow Sea area since 1846 are analysed.There are major periods of 6 years,12 years and 57 years and periods of 63 years,69 years and 75 years besides in activity of strong earthquakes of the area.Based on commensurable and clustered characteristics of activity of strong earthquakes,the trend of strong earthquakes in the area in future is forecasted.The forecasting results are proved.
