摘要
2003年12月10日台湾台东海外(23.1°N,121.4°E)发生MS7.0地震,福建水化地震台网震前有多项前兆数据出现异常变化,异常测项随着临震而增加。水化短临异常较为显著,出现趋势性上升的短期异常、震荡的临震异常、破年变异常、下降型异常等。除水温在震后1个月逐步恢复正常外,各测项或在临震或在震后即恢复正常。
An earthquake with M S 7.0 occurred in Dec.10,2003,in Taidong Taiwan Province.(23.1°N,121.4°E).The anomalous changes had been observed in Fuzhou Hydrochemical Monitoring Network before the earthquake.Many monitoring items were the anomaly and increased gradually with coming of the earthquake.The short term and imminent anomalies of ground fluids are remarkable.The anomalies are that the short term anomaly of rising trend and the surge in the impending term,the broken annual trend anomaly,the descending trend anomaly.The water temperature restored the normal in one month after the earthquake,but the others restored the normal immediately or in short term.
