AbstractUsing static water level observation data from Dehongfapa welland recorded co-seismic response events astheresearchobjects，theoperation，tidalfactor，observationaccuracy，andco-seismicresponsecharacteristicsof the static water level observation data of Dehongfapa well were systematically analyzed.The results showed clear diurmal variations in the solid tideaffcting the Dehongfapa wellstatic waterlevel，and the variation patern showedobvious daily and semi-daily waves，the observational data were highly accurateand astrong tidalresponse ability was noted.The wel exhibited a strong response to large earthquakes，and the static water level showed diferent co-seismic response patterns fordiffrent earthquakes，mainlyin the formofoscilations.The variationrange of theco-seismicresponseof the wel Waterlevel wasgenerallynegativelycorelatedwith thewell-seismic distanceand positively correlated with the magnitude，and theco-seismicresponse time was positivelycorelated with the wellseismic distance.Finally，the mechanismoftheco-seismicresponsecharacteristicsofthewaterlevelwascomprehensivelyanalyzed，andtherelated mechanism was preliminarily discussed in combination with the specific situation of Dehongfapa well.
