【摘要】 1994年9月16日在台湾海峡南部（22.6°N,118.7°E）发生了M_S7.3地震,发震时福州、厦门、漳州、东山等地普遍有感,个别房屋出现裂缝。震前福建省水化台网监测到水氡、水电导率、Ca²⁺、K⁺、Mg²⁺、水位、水温等地下流体群体异常,异常序列出现层次性,异常空间分布具有集中性,异常数量达到一定数值。更多还原

【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.更多还原
