碩士 / 國立成功大學 / 資源工程學系碩博士班 / 98 / Radon anomalous decline has been recorded at the Antung hot spring in eastern Taiwan prior to 2008 MW = 5.4 Antung earthquake. Prior to the earthquake, radon decreased from a background level of 102 pCi/L to 44.2 pCi/L. The
Antung hot spring is situated in a fractured aquifer of limited recharge surrounded by ductile mudstone. Under such geological conditions, in-situ volatilization of groundwater radon can explain the recurrent radon anomalous decrease. The major components of dissolved gases in groundwater are nitrogen and methane. We started to monitor groundwater radon, nitrogen and methane in November 2009 and are expecting to catch anomalous declines of radon, nitrogen and methane precursory to future large earthquake.
