Abstract：Based on comprehensive collection and systematical analysis of China water temperature observatory dynamics in 2008 within nearly 300 wells, we first ascertain the relationship between water temperature dynamics and earth tide and analyze anomalous change before and after the May 12th Wenchuan MS8.0 earthquake. Second, we clear the normal drill water temperature dynamics in year time and the basic features of temperature tidal effects, determining that there are 14 abnormal wells before earthquake. We summarize anomaly patterns and the spatial-temporal characteristics, analyzing coseismic corresponding characteristics of 125 wells. Finally, we further demonstrate possibilities and problems in water temperature and seismic monitoring, and come up with upgrading the hydrothermal observation network to a geothermal observation network, to explore the new ideas in the study of the relationship between crust thermal and seismic activities.
