摘要
利用地震活动平静参数Wq值方法,对1986年门源6.5级、2016年门源6.4级两次地震前Wq值的空间演化特征进行了对比研究,结果显示,两次门源地震前,震中及周边区域均出现了地震活动性参数Wq值的空间区域出现—扩大—收缩—扩大—收缩的异常,但两次异常的演化过程的持续时间和发震时的特征有所不同。
In this paper, we studied the spatial evolution of the Wq value before the two Menyuan earthquake (Menyuan 6.5 earthquake in 1986 and Menyuan 6.4 earthquake in 2016 ) .The results shows that the anomalies of Wq value in the epicentral and surrounding area were found in bout earthquake. But the characteristics of the duration and evolution of the two anomalous evolution processes were different.
