Abstract We analyzes the Danjiangkou well network 3 wells water level and water temperature observation data from 2013 to 2015. The normal dynamic individual test items are established. We study the different coseismic changes of water level caused by the Nepal M8.1 earthquake on April 25 in 2015 through the Danjiangkou fluid underground well network. The mechanism is explained. Corresponding relationships between magnitude earthquake response and surface wave magnitude and distance are deduced. We analyze the cause of the earthquake coseismic response waveform. The result indicate that well dynamic affect by rainfall water level has certain rules: monthly normal dynamics generally exhibit tidal and pressure effects; furthermore temperature dynamics are smooth, varying in the range of about 0.1 ℃.; different pulse changes of the Tangpa well are caused by different mechanisms of change between water temperature and well water. Different earthquake response characteristics on water level between Tangpa and Leizhuang wells may be associated with their different fault strikes. The water temperature of Shengwan well decreases much less than Tangpa well, caused by different lithology and groundwater type.
