| Abstract: | Based on the observational data of M6.2 Dayao earthquake happened in Yunnan Province on July 21,2003,systematic analysis on radon information has been studied.The anomalous distribution range of radon,features of anomaly and its relation with the time of earthquake occurrence have been obtained.It is valuable for us to distinguish and analyze the abnormal changes in radon observation,which is especially significance for mid-short term earthquake prediction. |
