Abstract On the basis of data of 277 countrywide geothermal precursor stations, the response of China geothermal earthquake precursor network to Wenchuan Ms 8.0 earthquake is studied. It is found that there are coseismic and postseismic changes in 134 stations. According to the form,co-seismic response and postseismic adjustment can be devided into four types:gradual change,step change and resuming,impulse and oscillation.In adition,it is found that the postseismic adjustment of geotherm contains the information of the adjustment of local strain status.
