本文研究了我国历史与现今中强以上地震的发震时刻与倾斜固体潮的关系。结果表明,地震发震时刻位于震中区当天倾斜固体潮的峰值时段上。孤立型地震的发震时刻往往与震中区倾斜固体潮极大值对应;原地重复发生的地震,其发震时刻所处的倾斜固体潮背景相同;逼近地震与主震发震时刻的倾斜固体潮背景相同的占70%;大震后有60%的强余震与主震发震时刻的倾斜固体潮背景相同。据此,成功地预报了门源6.4级地震后的较大余震。
In this paper, we study the relationship between the onset of strong earthquakes and the occurrence of tidal solid tides in China’s history and present. The results show that the time of the earthquake is located in the peak period of tidal solid tide on the same day in the epicenter area. The seismogenic time of the isolated earthquake often corresponds to the maximum value of the trough solid tide in the epicenter area. The repeated tidal earthquakes have the same tidal solid tide background at the time of the earthquake occurrence. 70% of the same tidal background; 60% of the strong aftershocks after the earthquake are similar to the tidal solid tide background of the main shock at the time of the earthquake. As a result, a large aftershock after the M6.4 earthquake in Menyuan has been successfully predicted.
