【Abstract】 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.更多还原
