摘　　要：1998年10月至1999年1月,在宁蒗与盐源之间发生了5次5级以上地震。我们根据西昌地震遥测台网的记录,在震前对该系列地震作出了较好的预测。分析认为:震前的短期空区、前兆震群甚至有直接前震是该系列地震的震兆异常;5次中强以上地震彼此有内在联系,又有一定的独立可分性,余震衰减都比较快,是本震例的序列特征。Form October 1998 to January 1999,five M S≥5 0 middle strong earthquakes happened between the Ninglang and Yanyuan.We according to data for the seism remote sensing station of Xichang,preferable forecast them before the earthquakes.Had analysed to consider:the seismic gap before earthquake,precursor earthquake swarms and restricted pre earthquake were thems seismic precursor.Five M S≥5 0 middle strong earthquakes have immanent affiliation each other,and have definite indie separability.Their aftershock attenuation soon is its sequence characteristic.
