Abstract: We have analyzed correspondent relation between the anomaly of water radon observed at Fenman well and earthquakes which occurred nearby or far away. We found that such correspondent relations look good before 40 major earthquakes including the events in Japan Sea. So we suggest that the Fenman well is sensitive to reflect earthquakes and associated with special geophysical conditions.

Key words: Radon in groundwater, Anomaly, Reflecting earthquake ability

摘要： 系统分析了吉林省丰满地震观测井的水氡异常及其与远近地震的对应关系,发现在日本海等地的40次中强以上地震之前有很好的对应关系。因此,笔者认为丰满井是一口映震灵敏井,并对映震灵敏的条件作了初步讨论。
