Abstract:: The water temperature in Kaiyuan Well started to rise and drop anomalously since March,2020. To find the cause,we checked the possible influencing factors like the observational environment of the Well,the power supply system of the water-temperature instrument,and further conducted a comparative monitoring of the water temperature at different depths in the Well. On the basis of the structure and the aquifer of the Well,we discussed the physical mechanism causing the anomalous fluctuation of the water temperature in the Well. We found that the environmental factors or the power supply system did not cause the variation of the water temperature; the main reason was that the rock mass deformation caused the reservoir fissures to close or open,then the hot water in the reservoir fissures became less or more. As a result,the water temperature in the Well consequently fell or rose rapidly. The regional tectonic activity intensified,giving rise to the rock mass deformation and causing medium- and strong-earthquakes in the vicinity.
