With the help of a case study, radon can be used as a tracer to determine the saturation in a naturally fractured reservoir. Well tests were conducted to estimate aquifer transmissivity before and after the 2008 Mw 5.4 Antung earthquake. Anomalous declines in both groundwater radon concentration and aquifer transmissivity were observed precursory to the 2008 Antung earthquake. Water relative permeability calculated based on the field data was found to be higher than that calculated by the Corey model but lower than that of the X-Curve model.
