摘要
分析了聊古 1井水氡测值在 1981年 11月 9日宁晋MS5.8地震 (Δ =150km)前和 1983年 11月 7日菏泽MS5.9地震 (Δ =150km)前的异常变化 .在地震前 5～ 15天该井水氡出现明显的高值异常 .地震发生在氡值下降的过程中 .这可能是该井水氡的一项短临异常指标 .
Anomalous character of radon content in Liaogu 1 well before the Ningjin M S5.8 earthquake on November 9,1981 and the Heze M S5.9 earthquake on November 7,1983 are analysed. Radon content in the well has gone up by a wide margin 5～10 days before the earthquakes.The earthquakes occurred during radon content dropping.Therefore,the anomalous changes of radon content of the well can be regarded as a short impending prediction index.
