Abstract The concentrations of H2 in soil gas were surveyed along two lines, which crossed the known Yinchuan buried fault. The maximum abnormal concentration of H2 lying at the Xinqushao trench of the Yinchuan buried fault in soil gas was 73.6?10-6. It is suggested that the abnormal concentrations of H2 in soil gas were mostly influenced by the dip angle of the buried fault and the activity of the fault. Soil gas H2 measurement has certain indicative significance for the buried fault.
