| Abstract: | In this paper,we analyzed the water temperature data of Su No.22 well since 2008 and found that there are eleven anomalies during the observation of water temperature.Through analyzing,we eliminated interference factors of instrument failure,human disturbance and rainfall etc.Comparing with earthquake activity,we can see that the water temperature of Su No.22 well has good earthquake reflection ability.The water temperature anomalies which are with the drop amplitude more than 0.005℃ have a good relationship （with the rate of 4/7）with earthquakes which have a magnitude bigger than ML 4.0 and occurred in the range of 300 km around. |
