The Sichuan Earthquake Administration, together with the Mianyang Emergency Management Bureau and local government departments, went to the site on the 14th to verify the temperature rise of the old well in Mianyang, and believed that the rise in water temperature in the well was caused by the leakage and short circuit of the pump.
On the 14th, experts from the 909 hydrological team of the Sichuan Geological and Mineral Bureau ruled out the problems of geothermal and geological disasters.
After the well was drained on the 14th, the water temperature was observed every day. The water temperature of the well was in a continuous decline process. The current water temperature is basically the same as that of the surrounding wells.
