| 摘 要： | 本文详细介绍了１９９２年２月１８日南日岛地震前，福建地下水动态观测网中４口深井所记录到的水位前兆异常。其异常时间以短临为主，基本同步。异常形式主要表现为水位升降，水位固体潮形态畸变和相位错动以及典型的“临震回跳”等。本文还对提高井网监控能力以及沿海地区井受“复合潮”影响等诸问题进行了讨论。

| Abstract: | This paper introduced in detail the precursory anomaly of water level from 4 wells in Fujian Underground Water Dynamic Observation Network recorded before Nanri Island earthquake occurred on Feb,18,1992. The anomalies are basically synchronous. The anomaly pattern is mainly expressed as the elevation and subsidence of water level, distortion and phase disturbance of solid tide form of water level, and typical 'impending rebound" and so on. This paper discussed the problems related to improvement of monitoring and controlling capacity of the well network and influence of "Compound tide" on the wells in the coastal area. |
