Abstract:We use GNSS measurements from Sichuan province to analyze the seasonal load displacement and stress-strain field. Combined with precipitation data, the effect of seasonal hydrological load on crustal deformation and stress-strain near active faults in this region are analyzed. The results show that there is a strong spatio-temporal correlation between the seasonal surface displacement and precipitation in Sichuan. The stress disturbance caused by the periodic change of hydrological load has a certain regulating effect on the stress accumulation mode of the active fault zone, which then affects the motion state of the active fault zone.
