台湾海峡7.3级地震前地下流体前兆异常

对１９９４年台湾海峡７．３级地震前后观测到的地下流体异常变化进行了分析，并尝试用层次跟踪法（ＨＴＭ）做检验性预测。利用１１个水点、３８个测项１９９０年１月￣１９９４年８月的资料，计算得到的发震时间为１９９４年８月下旬至１０月上旬，而对发震地点和震级，该法难以给出预测结果。

ANALYSIS OF THE SUBSURFACE FLUID PRECURSOR ANOMALY BEFORE TAIWAN STRAIT EARTHQUAKE OF Ms7.3

After analyzing the data observed in Guangdong and Fujian provinces, the author tried to give a testing prediction about the Taiwan Strait earthquake by the HTM. The data of 11 subsurface fluid observation stations were used, which were from January 1990 to August 1994. The result of analysis was that the earthquake would occur between the last ten - day of August and the first ten - day of October 1994, but the HTM can not predict the occuring place and the magnitude.
