The δD values of molecular hydrogen in soil gases obtained from sites along the Yamasaki fault, one of active faults in Southwest Japan were measured. The δD values were in the range between -770 and -470‰, which suggests that molecular hydrogen is formed by chemical reactions between groundwater and the fresh surface of basement rocks formed by the fault movement.
