摘要
Variations of temperature are accompanied by exchange of heat,and thus,coseismic response of water temperature during the activity of earthquake should obey the laws of thermodynamics.Taken the cases of the 2008 Wenchuan MS8.0 earthquake in China and the 2011 Fukushima 9.0 Earthquake of Japan,and based on the coseismic response data of water temperature collected from well ZK26 in Haikou,Hainan province,we analysed the relationship between variations of water temperature and heat conduction as well as the thermodynamic mechanism by numerical simulation of thermodynamic conduction equation.Then through forward modeling,we obtained several simulation curves of coseismic effect of water temperature along the axis of well at different times,and the water temperature simulation curves fit the measurement curves approximately.Our research indicates that the way of coseismic response(ascending,descending or stable) has something to do with factors like the locations of sensors,distribution and locations of heat sources,the span between sensors and heat sources and so on.
