Abstract: The author analyzed and researched anomalous variations of water radon and it's forming mechanism in Yi shui w ell since March 28, 2001combined with confirmation of water radon anomaly and analysis result s of sampling sites in and around Yishui wall as w all as geological structures and surveying results of mobile geomagnetism. The results of the analysis and research indicates that anomaly of descendent variation of water radon in Yishui well is interrelated with streng thening of stress activity and intensifying of structure activity of Yishui-Tangtou fault and Yishui-Yiyuan fault.
