| Abstract: | One large earthquake sequence(Ms = 7.3) occurred in the south of Taiwan strait on September 16, 1994(22.6?N, 118.7?E). When the main shock occurred, the felt area included Fuzhou, Xiamen, Dongshan etc.. There were some buildings, where cracks appeared. The group anomalies of water Randon, water conductivity, Ca2+, K2+, Mg2+, water level, water temperature atc. have been observed in Fujian Hydrochemical Monitoring Network before the main shock occurrence. The anomaly segnence showed the feature in clustered pattern. The spatial range of the anomalies was relatively concentrated. The amount of the anomalies reached a certain value. |
