The Transition and Rising Causation Analysis of the Static Water Level of Xinmin Well in Liaoning Province

WANG Xi-long;FU Cong;LI Meng-ying;ZHANG Li;LI Qiao;Earthquake Administration of Liaoning Province;  
Water level in Xinmin well has turned to rise and accelerate since July 2016, And the max amplitude was about 1.2 meters. But the water temperature in the same well did not change. Checking the observation system, the regional construction characteristics and investigating surround environments,we found that a large open pit was located northeast to the well about 50 meters, the rainfall water accumulation in which may cause the rising changes. Based on the analysis of geological characteristics, geochemical characteristics of the Xinmin well, and the regional precipitation characteristics,we found that the changes of water level for the fluid well and the volumetricstrain well maybe not caused by tectonic stress of earthquake preparation, but the continuous rainfall which lead the amount of water accumulated increased in open pit.
