英文摘要	Although different methods have been employed to study the earthquake-induced changes in aquifer permeability (e.g., tidal/barometric pressure response and analytical models), identification of the mechanism is usually hindered by the limitation of application conditions or multiplicity of solutions. A numerical simulation that couples flow and heat transport is developed in the present study to explain the coseismic responses that followed two large earthquakes (Mw 7.0 Lijiang earthquake on 3 February 1996 and Mw 9.1 Sumatra earthquake on 26 December 2004) at Banglazhang #1 hot spring, China. The results show that decreased spring discharge and temperature are attributable to earthquake-induced permeability decrease, which can be related to the blocking of narrow fracture apertures. Analysis of the model revealed that seismic waves may have caused heterogeneous changes in permeability within the fault zone hydrothermal system, which led to nonsynchronous changes in spring flow and temperature. Our study contributes to an enhanced understanding of the impact of the evolution of earthquake-induced permeability in hydrothermal systems. ©2020. American Geophysical Union. All Rights Reserved.
