乌鸦嘴泉水氡动态异常与恒春海域强震的关系

The relation between the dynamic anomalies of water radon in Wuyazui fountain in Fuzhou and earthquakes in Taiwan Province

排除了乌鸦嘴泉水氡测项可能存在的影响因素，结合该泉氟离子和华安汰内井、泉州四至井水氡先后出现的异常，论证了2004年秋至2006年冬福州乌鸦嘴泉水氡存在的年动态畸变异常的可靠性，认为该异常可能是2006年12月26日台湾恒春海域M7．2地震的中长期前兆异常，并结合历史资料，分析恒春海域强震前福州乌鸦嘴泉水氡的变化特点。从几个测点的水氡先后出现长达1～2年的年动态畸变异常，认为在关注水氡的短期或短临异常的同时不能忽略其中长期的异常变化。

In this paper, the reliability of water Radon anomaly in Wuyazui fountain during 2004 2006 period is demonstrated after removing all possible interferential factors and referring to the F1 anomaly at the fountain and the water Radon anomalies occurred in Tainei well, Anhua and Sizhi well, Quanzhou. The anomaly is considered to be the long term precursor of Hengchun maritime space M 7.2 earthquake in Taiwan on Dec 26, 2006. The variation characteristics of the water Radon anomaly at Wuyazui fountain in Fuzhou before the Hengchun strong earthquake is analyzed with referring to historical data. Considered that the duration of annual dynamic aberrances of water Radon at these measure points are as long as one or two years, we suggest that the long term anomalous variation of water Radon should not be ignored while paying attention to the short term variation of water Radon.
