【Abstract】 In this paper,the observation data of groundwater levels in well/spring and water radon with continuous and stable observation in Shanxi province and its adjacent regions are collected.The special method for extracting intermediate-term and intermediate-short-term anomalies was chosen and used to analyse the anomalies of groundwater level and water radon before Datong M6.1 and Zhangbei M6.2 earthquakes.Based on the statistical data,the index and method for intermediate-term and intermediate-short-term strong earthquake forecast judging by the precursor anomalies in underground liquid in this area are suggested.更多还原
