On 23 January 2024, a MS7.1 earthquake struck Wushi County, Xinjiang Uygur Autonomous Region, marking the largest seismic event in Southern Tianshan (STS) region past century. This study investigates relationship between hydrothermal fluid circulation and activity by analyzing chemical composition origin of fluids natural hot springs along Maidan Fracture (MDF). Results reveal two distinct hydrochemical water types (Ca-HCO3 Ca-Mg-Cl). The δD δ18O values indicating spring are influenced atmospheric precipitation input altitude. Circulation depths (621–3492 m) thermal reservoir temperatures (18–90 °C) were estimated. Notably, high 3He/4He ratios (3.71 Ra) mantle-derived 3He content reached 46.48%, confirming that complex gas–water–rock interactions occur at fracture intersections. Continuous monitoring site S13 (144 km from epicenter earthquake) captured pre-and post-seismic hydrogeochemical fingerprints linked to earthquake. Stress accumulation MDF induced permeability changes, perturbing equilibrium. At 42 days pre-Wushi earthquake, δ13C DIC exceeded +2σ thresholds (−2.12‰), signaling deep expansion CO2 release. By 38 Na+, SO42−, surpassed 2σ levels, reflecting hydraulic connection deep-seated shallow networks. Ion concentrations isotope showed dynamic shifts during which revealed episodic stress transfer fault asperities. Post-Wushi closure reduced input, causing drop −4.89‰, with ion returning baseline within 34 days. Trace elements such as Be Sr exhibited anomalies 12 before while like Li, B, Rb 24 after Hydrochemical captures critical stress-induced signals, offering vital insights for forecasting tectonically active regions.
