摘　　要：德令哈6 6级地震发生在青海省地震局2003年度会商确定的应注意地区内,震前测震学出现多项中短期异常。该地震序列从其能量释放比、震级差均符合主震-余震型判断指标,为主震-余震型序列。序列跟踪工作总结出该序列早期阶段(20天内)预测强余震的几项指标。Delingha earthquake with Ms6.6 occurred in the area determined by yearly conference held by seismological bureau of Qinghai province,many seismometry items appeared middle and short terms anomalies before the earthquake.It is main-aftershock determined by energy release ratio and magnitude differences.Some items of predicting the aftershocks in early period(20 days)were provided according to the sequence.

关 键 词：德令哈地震 测震学异常 序列特征
