The establishment and development of geochemical monitoring in Taiwan are introduced. From a dataset covering several years of continuously monitored soil gas, some anomalously high Rn concentrations at specific times were identified using a statistical technique. We found that many Rn anomalies were observed in soil gas prior to the occurrence of impending earthquakes. Each station is sensitive to only the seismic events in its specific surrounding area. Comparing the preseismic events at different monitoring stations, we can further identify the sensitivity zone of each monitoring system and then may be able to propose the potential area of the epicenter of the impending earthquake. The relative peaks of soil-gas anomalies, at two or more stations at their respective occurrence times, could eventually enable satisfactorily precise predictions of the location, time, and magnitude of an impending earthquake. The long-term monitoring of gas or fluid composition at appropriate sites or near fault zones is helpful for understanding the mechanism and process of fault and earthquake activity.
