一、引言 1995年7月至1996年2月7个月内,云南省境内由南向北连续发生中缅边境7.3级、武定6.5级、丽江7.0级地震,如此连发性地震在历史上也少有。震前断层形变测点均有较好的中期及短期前兆反应,云南省地震局曾将永胜测点的较大异常做为对中缅边境7.3级大震预测的重要依据之一,国家地震局地壳应力研究所又根据永胜巨大异常系列的发展曾对丽江7.0级地震进行过预测,国家地震局预报中心在震前又根据永胜变化进一步 I. Introduction From July 1995 to February 1996, within the territory of Yunnan Province, there occurred a series of consecutive 7.3-magnitude Sino-Myanmar border, 6.5-magnitude Wuding and 7.0-magnitude Lijiang earthquake from south to north in the history of this series of events Also rare. Before the earthquake, the measuring points of fault deformation have better medium-term and short-term precursory response. Yunnan Seismological Bureau once considered the large anomaly of Yongsheng survey point as one of the important bases for the prediction of the 7.3-magnitude earthquake on the Sino-Burmese border. The national earthquake Bureau of Crustal Stress and according to Yongsheng huge anomaly series of development on the magnitude 7.0 earthquake in Lijiang had been predicted, the National Seismological Bureau prediction center before the earthquake and according to Yongsheng changes further
