摘　　要：应用“八五”地震攻关成果及相关软件 ,对 1994年 9月 16日台湾海峡 7 3级地震前震中周围中小地震活动性参量的计算和分析表明 ,震前震中及邻区地震活动明显增强 ,累计频度和应变释放发生突变 ,从 1991年起出现孕震空区 。The Seismicity parameters around the epicenter region before the M S7 3 Taiwan strait earthquake occurred on September 16,1994 are analyzed by using correlative computing software. The results show that the regional seismicity is obviously intensified , the both cumulative frequency and stain release arise suddenly changes from the linear to non linear. The seismogenic gap appeared since 1991, and the medium short anomalies of several seismicity parameters in time and space show obvious features before the earthquake.
