- Abstract:
- The observatory data of the radon in groundwater in Ganzi Seismic Station since the station was built up is systematically processed and the several interfering factors are analyzed.We have studied the characteristics of the connections among the radon changes in groundwater and the earthquakes above M5.0 occurred within the distance of 200km,and M6.0 within 300km around the seismic station.Our results show that since 1974 when the observatory data were recorded,the radon contents in groundwater presented anomaly changes of mid-short term for several times.These anomalies have features of breaking the annual changes and changing the correlation coefficient.The anomaly changes of radon content in groundwater are related to the temperature,the flow of groundwater,and the changes of rock stress-strain and the crust activity.The time of most short-imminent anomalies is concentrated within 1 month,the anomaly forms show sudden increase and decrease,and the amplitude is above 10%.There is no obvious correlation between the anomaly amplitude and the magnitude.
