一次4.6级地震前的气氡异常变化分析
|
摘要
本文对聊古Ⅰ井气氡的日均值、整点值和离散程度等进行了处理和分析,发现在2006年4月9日河南濮阳4.6级地震前有显著的异常变化。综合分析认为,气氡的异常属于短期、场兆异常。本文还对该异常的机理及有关问题进行了讨论。
This paper processed and analysised the data of daily mean value and hourly value and scattered degree of gas-radon in Liaogu I well.It has been found that there is obvious anomaly appearance before the earthquake with magnitude 4.6 in Puyang of Henan province on April 9,2006.It was considered that the gas-radon's anomaly is belong to the short period and field anomaly after comprehensive analysis.The anomalous mechanism and some problems correlated with it were discussed in this paper at the same time.
