| 摘 要： | 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。

| Abstract: | This paper analyses the relationship between the original times of the historical, recent moderate strong earthquakes and the tilt earth tide. The results show that the original times of earthquakes are located on the peak values of time series of tilt earth tide in the epicentral region; Generally, the original times of isolated events correspond with the maximum values of tilt earth tide in the epicentral region; To the recurrence events in original place, the background of tilt earth tide is similar to that of the original times; The background of tilt earth tide of 70% close events is similar to that of main shocks at the original times; The background of tilt earth tide of 60% strong aftershocks after large earthquakes is similar to that of main shocks at the original times. On the basis of this, we have tried to predict larger aftershocks after the Menyuan earthquake (M=6.4). |
