Abstract:Based on measurement, obtained through the soil gas detection method, of the radon and hydrogen in soil gas on 3 different positions of Shuangxi-Jiaoxiyang fault in Shanxi reservoir district, we find that the values of radon and hydrogen in soil are higher near the fault fracture zones or veins, and the values of radon and hydrogen in soil far away from the fault fracture zones are lower. By the application of fault gas detection method in detecting buried faults, the fault crossing location near Baoshanyang village can be confirmed. We also find that the values of radon and hydrogen in soil gas crossing the seismogenic fault are significantly higher than the values crossing the non-causative fault. This shows that the radon and hydrogen in soil gas are closely related to seismicity, so continuous measurements of soil gas near the Shuangxi-Jiaoxiyang fault are suggested to provide the basis for seismic forecast and shock tendency estimation in Shanxi reservoir district.
