摘要
20 0 1年 6月 2 8日至 7月 1 1日先后在大同—阳高、唐山陡河发生 ML4 .1和 4.0地震 ,此前我们曾根据大华北地区地震活动性背景异常、区域中小地震活动特征以及部分地震短临前兆观测异常 ,对这两次中等地震进行了尝试性短临预测。本文系统总结了对这两次中等地震的预测过程 ,这对于我们坚定地震预测信心、进一步做好中等甚至中强以上地震的预测可能具有积极意义。
Two earthquakes( M L4.1 and M L4.0)occurred succssively in Yanggao of Datong and Douhe of Tangshan in Jun.28 and Jul.11,2001.Based on the background anomalies of seismicity in north China and the feature of local small earthquake activity as well as some imminent precursory anomalies,we had given some trial imminent prediction before the two events.In this paper,the prediction course is summarized systematically,which may be significant to the prediction of medium and even strong earthquake.
