“…The Jinhekou-Meigu fault (JMF) is sub-parallel to and to the west of the EJF. The Xiluodu reservoir is a typical river-type reservoir with a surface impoundment extension of ~204 km along the Jinsha River (Yin et al, 2015), and intersects the EJF and HLF upstream. The minimum distance from the Xiluodu reservoir to the MYF and JMF is ~10 km and ~30 km, respectively.…”

 The plausible link between the Xiluodu reservoir impoundment and the increased seismicity is evidenced by spatio-temporal correlations. The pore pressure diffusion and reservoir water load can contribute to fault reactivation and earthquake triggering in the Xiluodu area. The fault criticality analysis reveals that the NNW-and NS-striking faults downstream the Jinsha River are more prone to reactivation.

“…According to the different factors and mechanisms that in uence the induction of landslide deformation, landslides can be divided into the following ve types: (1) (Gong et al, 2022;Zhou et al, 2022). The TGRA is located in western Hubei and eastern Chongqing, where storms frequently occur, and landslides induced by heavy rainfall and uctuations in the reservoir water level pose severe threats to shipping and the safety and lives of residents living on the reservoir bank (Yueping et al, 2015). Field surveys and statistics have previously indicated that rainfall-hydrodynamic pressure landslides account for up to 42% of the 319 landslides; therefore, it is essential to study landslide development to determine methods of preventing and controlling rainfall-hydrodynamic pressure landslides and ensuring normal TGRA operations.…”

A 16-year surface macroscopic survey and GPS monitoring results from the Sanmendong landslide in the Three Gorges Reservoir Area have demonstrated that the deformation degree of the landslide is distinctly correlated with rainfall and fluctuations in reservoir levels. In this study, the seepage field and stability coefficient of Sanmendong landslide deformation under the conditions of rainfall were estimated, and fluctuations in the reservoir water level and their coupling effects were simulated and calculated, respectively. The simulation results revealed that as the water level rises, the seepage force is directed to the inside of the slope, thus creating conditions that bolster landslide stability. However, when the reservoir water level drops or rainfall occurs, the seepage force is directed to the outside of the slope, thereby hindering landslide stability. GPS monitoring data and the correlation between reservoir water level fluctuations, rainfall, and landslide deformation were further analyzed. The analysis revealed a positive correlation between rainfall and the displacement rate at monitoring point ZG361, with a high grey correlation degree (0.761). However, the correlation between the rate of fluctuating reservoir water levels and the displacement rate at monitoring point ZG361 was insignificant. The stability calculation demonstrated that under normal Three Gorges Reservoir operation, a decrease in water level only decreases the stability coefficient by < 1%, whereas the heavy rainfall process decreases the stability coefficient by > 10%. The above results prove that the rainfall is the primary driver governing Sanmendong landslide deformation.
