西藏中部及其与青海邻近地区强震活动特征与玛尼7.5级地震预测研究

依据西藏中部强震活动特征及１９８５年以来中国大陆强震活动新格局，于１９９６年将藏北玛尼一唐古拉山口一带列为未来几年７１／４级地震危险区。这旬刚发生的１９９７．１１．８玛尼７．５级地震有较好的对应。再次表明采用活构造与强震研究相结合、震源区个性和地震带（区）共性相结合，追踪大震发展过程及研究不同必质的强震活动图象等分析方法是有研究前景的。

STUDY ON THE STRONG SEISMICITY FEATURES IN MIDDLE TIBET AND ITS ADJACENT REGIONS TO QINGHAI AND THE Ms 7.5 MANYI EARTHQUAKE PREDICTION

Based on strong seismicity features in middle Tibet and new pattern of strong seismicity in Chinese mainland since 1985,Manyi-Tanggula Mountain Pass in north Tibet was classified as seismic risk region with M71/4 in future several years by the authors in 1996,which has corresponded to the M7 5 Manyi earthquake occurred on November 8,1997.It is shown again that these methods including combining active tectonics with study on strong earthquakes and the specific characters in focal region with general characters in seismic zone,tracing development course of large earthquake and study on strong seismicity patterns with different features have the prospects for further research.
