摘要

宁德一号井气氡多次出现与气温不同步现象。采用EIS2000软件,对异常进行提取,结果表明,2008年2月至3月,气氡测值与气温变化明显不同步,可能是距离该点87 km的福建古田水口M_L 4.8地震前兆异常。
The asynchronous phenomenon of air radon with temperature in Ningde No.1 well was occurred many times.The anomalies of air radon were verified and analyzed.With the suitable software EIS 2000,the radon anomaly is extracted.The results indicated that the asynchronous changes of air radon with temperature in February and March of 2008 may be the precursor of Shuikou M_L 4.8 earthquake,Gutian,Fujian,which is with an epicenter distance of 87 km.
