The annual variation of water temperature in the Fuxin well accelerated since August 2015,and the max amplitude was about 7.2‰℃. At the same time,the tricstrain well 15 meters from the water well also had descent variations for the water level. Checking with the observation system and analyzing the regional construction characteristics and surrounding environment,we find that there is a new deep well located in the northeast about 1km,which has continuous pumping that may lead to the decrease for water temperature and water level. Comparing the pumping time of the new well with the precursory data,we find that the water temperature,the volumetric strain and the water level have the correlation with the new well in terms of cause,spatial and temporal factors and signal intensities. These result shows that the changes of the temperature of the well and the water level of the volumetric strain well are not caused by tectonic stress of the earthquake preparation,but by the water pumping interference of the nearby new well.
