摘要
研究了河北阳原2井水氡资料的趋势变化和年变化特征,对水氡与气温的负相关特性进行了分析,并对该井水氡资料的映震能力作了统计分析和R值评判。结果表明,河北阳原水氡资料从长期到中短期的异常变化与该区的中强地震活动有较好的对应关系,根据中短期异常可得出4个月以内中等地震发生的概率为66.67%。
Variation trend and yearly variation characteristics of Radon in groundwater from the well No.2 in Yangyuan ,Hebei are deeply studied. Statistic analysis and R value judgment for the reflecting earthquake ability of Radon in groundwater from this well are made. The result shows that the abnormal variations ranging from long term to mediumshort term are well related to the activity of mediumstrong earthquakes. The probability of successful predictions,based on the medium-short term anomalies, for mediumstrong earthquakes which would occur in 4 months was 66.67 %.
