本文用所推导出的表示地震时间序列特征的W参数,对1966年邢台6.8(Ms)地震和1975年海城7.3(Ms)地震序列资料的处理得到:在W—t图中,当W值接近或低于中误差σ时,即很可能有强余震发生;而当W值低于平均水平时可认为是强余震前兆信息的开始.W—t曲线与强余震对应结果较好,邢台强余震对应结果鉴定评分R=0.659,海城强余震的对应结果鉴定评分R=0.501,表明预测效果是比较显著的.
In this paper, using the W parameters derived from the characteristics of seismic time series, the data of the 1966 Xingtai 6.8 (Ms) earthquake and the 1975 Haicheng 7.3 (Ms) earthquake sequence are obtained. In the Wt plot, Close to or below the median error σ, that is, strong aftershocks are likely to occur, while when the W value is below the average level, it can be considered as the beginning of strong aftershock precursors. The W-t curve correlates well with the strong aftershocks, Aftershock corresponding result identification score R = 0.659, Haicheng strong aftershock corresponding result identification score R = 0.501, which shows that the prediction effect is quite significant.
