“…Geothermal springs are primarily found in the Yalabamei, Zhonggu, Erdaoqiao, and Yulingong geothermal areas of the XFZ (Figure 1c). Up to now, previous studies have interpreted the genesis of geothermal springs in the Erdaoqiao and Yulingong geothermal areas using geophysical and geochemical methods [16][17][18][19][20][21][22][23][24]. However, only a few previous investigations analyzed the geothermal springs in the Yalabamei and Zhonggu geothermal areas [25], and thus the conceptual model of the geothermal system is unclear.…”

Abundant geothermal waters have been reported in the Yalabamei, Zhonggu, Erdaoqiao, and Yulingong geothermal areas of the Xianshuihe Fault Zone of western Sichuan, southwestern China. This study focused on the hydrogeochemical evolution, reservoir temperature, and recharge origin of geothermal waters using hydrochemical and deuterium-oxygen (D-O) isotopic studies. Shallow geothermal waters represented by geothermal springs and shallow drilled water wells are divided into two hydrochemical groups: (1) the Ca–Na–HCO3 type in the Erdaoqiao area, and (2) Na–HCO3 in other areas. Deep geothermal waters represented by deep drilled wells are characterized by the Na–Cl–HCO3 type. The major ionic compositions of geothermal water are primarily determined by the water–rock interaction with silicate and carbonate minerals. The reservoir temperatures estimated by multi-geothermometries have a range of 63–150 °C for shallow geothermal water and of 190–210 °C for deep geothermal water, respectively. The δ18O and δD compositions indicated geothermal waters are recharged by meteoric water from the elevation of 2923–5162 m. Based on the aforementioned analyses above, a conceptual model was constructed for the geothermal system in the Xianshuihe fault zone.

“…Permeability controls groundwater flow and the advective transport of heat and solutes in the shallow crust and is not a static parameter (Ingebritsen & Manga, 2019). Permeability change has been widely accepted as a mechanism for explaining earthquake‐induced changes in water level, temperature, flow rates, and chemical composition (Elkhoury et al, 2006; Li et al, 2019; Manga & Wang, 2015; Wang et al, 2012; Yan et al, 2014). Different methods have been employed to find permeability changes during earthquakes.…”

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.

“…Groundwater level and temperature anomalies have often been documented in association with earthquakes (Chen et al., 2016; Igarashi et al., 1992; G. King and Cocco, 2001; Kitagawa et al., 1996; Koizumi et al., 2004; Matsumoto et al., 2003; E. Roeloffs et al., 1997; Shi et al., 2015). Hydrogeochemical interpretation related to these anomalies was also undertaken in many studies (Barberio et al., 2017; Claesson et al., 2004; B. Li et al., 2019; Skelton et al., 2019; Toutain et al., 1997; Wakita, 1996; Woith et al., 2013). However, understanding groundwater system responses to earthquakes using isotopic approaches remains challenging.…”

On 15 November 2017, a M w 5.5 earthquake occurred in Pohang City in southeastern Korea. The Pohang earthquake is the most destructive earthquake recorded in South Korea since 1978, when instrumental monitoring of seismicity began in South Korea. Several previous studies have indicated that the Pohang earthquake was most likely triggered by events associated with enhanced geothermal system (EGS) activity near the epicenter (
