In the process of underground fluid observation about earthquake, the characteristics of groundwater recharge sources, circulation and evolution are the basis for earthquake precursor analysis relevant to underground fluid. Currently, the methods of water chemistry, environmental isotopes and groundwater dating are becoming useful tools in the research on the groundwater recharge and evolution. These methods also can be used to both study the hydrogeological environment of underground fluid observation sites and analyze the groundwater recharge sources and circulation of the sites, all of which will provide theoretical evidence and reference information to analyze earthquake precursory.

The groundwater chemistry types, water-rock interaction, groundwater reservoir temperature, circulation depth, recharge sources and height of the underground fluid observation sites in the study areas were analyzed and calculated, as well as groundwater age.

The study on the hydrogeology environment of underground fluid monitoring sites in earthquake belts will contribute to the application of water chemistry, environmental isotopes and groundwater dating in earthquake monitoring field. Although the methods especially groundwater dating have been applied few times in the science and research of earthquake underground fluid, they can be widely used in the near future according to the examples of relevant subjects.
