| Abstract: | The water temperature dynamic variation （daily, monthly and annual changes）, together with digital data of coseismic responses of water temperatures recorded at Jiaji well, Qionghai, Hainan Province during January 2007 and April 2010 and the strong earthquakes featu ring epicentral distance less than 8000kin and Ms≥7.8 are systemically analyzed. The result reveals that the coseismic effects of water temperature induced by distant earthquake are characterized by up pulse, which is different from the previous view of down pulse character- istic of coseismic effects of water temperature of non flowing wells. Water temperature chan ges depend on epicentral distance and earthquake magnitude. The mechanisms of coseismic effects of water temperature of wells in Jiaji can be interpreted as ＂admixture within layer＂. |
