Abstract On February 6, 2023, double M7.8 earthquakes occurred in Türkiye, and the co-seismic response of Shiyan Fangxian well and Zhongxiang Maling well is significantly different. The aquifer permeability coefficient of Maling well is much higher than that of Fangxian well, so the water exchange of well-aquifer system is more frequent and intense due to earthquake waveform. The hydroseismogram amplitude of static level is larger and the duration is longer. The aquifer water flowed to borehole caused by seismic wave. Controlled by the water temperature gradient and water temperature sensor position, the form and duration of water temperature response are different. The aquifer water temperature of Fangxian well is cold water compared with that at 65 m, so the water temperature at 65 m shows a downward step change. The aquifer water temperature is hot water compared with that at 105 m, and the distance is closer, so the water temperature at 105 m shows a upward step change and lasts longer. Under the mixed action of upper cold water and lower hot water, the water temperature at 290 m of Maling well is more affected by the upper cold water, so the co-seismic response at 290 m shows a downward step change. The water temperature sensor at 346 m is located in the hot aquifer at the bottom of well, so the co-seismic response shows a upward step change and lasts longer.
