Abstract On the basis of the scale value calibration of wellwaterlevel system in Fujian, the body strain responses of well water level, body strainmeter and extensometer to Wenchuan Ms8.0 earthquake are analyzed. The results show that all the response extent of above three instruments is about
10 -7～10 -8 which corresponds to the body strain of semidiurnal wave induced by tidegenerating force from moon and sun.
