Abstract:: The prediction efficiency of the water radon in Eryuan hot spring was tested by using Molchan diagram method,and the chemical composition,hydrogen and oxygen isotopes and water cycle characteristics of the spring water were studied.The results show that:①High value of water radon in Eryuan hot spring is more sensitive to the medium-strong earthquakes in the vicinity,and the most probable predictive period is less than 90 days before the earthquake event; ②The hydrochemical type of Eryuan hot spring is HCO₃·SO₄-Na,which has no direct hydraulic relations with the surrounding surface water and shallow groundwater; ③The water in Eryuan hot spring belongs to “partially-balanced water” and gets supply from deep source.
