| 摘 要： | On the basis of digital records from Tayuan well,we study coseismic effects of water temperature caused by re-mote earthquakes.The records show that the water temperature changes are consistently following the process ofdrop-rise-recovery regardless of focal mechanism or epicentral directions.The step amplitude of water temperatureincreases with the increase of earthquake magnitude,and decreases with the decrease of epicentral distances.Theyhave rather well correlation.Water temperature rising after earthquake is influenced by water level variations.Fi-nally,the mechanisms of coseismic effects of water temperature have been discussed.Preliminary study shows thataccelerated convection and mixing of different temperature water in virtue of seismic wave are the main causes ofwater temperature drops.Seismic wave accelerates water convection,which causes warm water to move up fromdeeper part of the well and cold water to go down from the upper part.Temperature probe will detect water tem-perature drops at early stage.After the occurrence of earthquake,as the fluctuation of water level gradually quietsdown,water temperature near the probe begins to rise.
