LUO Binsheng;CHEN Yonghua;Qinghai Earthquake Agency;
Through the analysis of the abnormal changes of radon in Huangyuan seismic station before and ofter Jiuzhaigou earthquake with M7. 0 on August,8 th,2017 in Sichuan province,the results showed that the short-term characteristics of radon values were declined before the earthquake and risen again after the event. After analyzing the reliability of radon values,it can be concluded that the short-term changes of radon values in Huangyuan seismic station before and after Jiuzhaigou earthquake with M7. 0 were precursory anomalies which would be the reference for earthquake prediction.
