摘要
本文系统总结了姑咱地震台气氡观测资料的使用价值、存在的问题,对姑咱地震台气氡观测值的年、月、日动态变化和仪器干扰进行了分析,并对姑咱台气氡在汶川8.0级地震和玉树7.1级地震前的异常进行分析,讨论姑咱气氡映震效能,认为姑咱气氡在两次强地震前异常形态的相似性和震后形态恢复的差异性,均表明姑咱气氡异常变化能够真实的反映两次强地震所处断裂带的应力变化,表明姑咱气氡具有很好的映震效能。
This paper systematically summarizes the data' s value of Guza seismic station gas radon and existing problems.It analyzed the instruments' interference and the annual, monthly and daily dynamic variation of the gas radon' s observation data at Guza seismic station. It also analyzed the anomalies of the gas radon at Guza seismic station when Wenchuan 8.0 earthquake and Yushu 7.1 earthquake happened, and discussed the earthquake reflecting ability of the gas radon at Guza seismic station. The similarities and differences of the gas radon anomalies before two strong earthquakes showed that Guza gas radon can truly reflect the stress changes on which fault the two strong earthquakes occurred. And it showed that Guza gas radon has a good earthquake reflecting ability.
