## 6 Conclusions  
This paper acquired the three-dimensional deformation field in the XSHFZ and its neighboring regions by integrating GNSS and InSAR velocity fields. The GNSS horizontal and vertical deformation velocities were used to evaluate the accuracy of the three-dimensional deformation field, and the residual standard deviations of the east-west deformation field, north-south deformation field, and vertical deformation field were 1.2 mm/yr, 1.4 mm/yr, and 0.88 mm/yr, respectively. Additionally, by utilizing the dislocation model and the Bayesian Monte Carlo inversion method, we further deduced the kinematic deformation characteristics of the XSHFZ. The kinematic deformation characteristics of the XSHFZ show distinct segmentation. In the middle segment of the XSHFZ, the slip rate is higher than at the two ends, with the Kangding segment having the highest average slip rate of 13.6 \(\pm\) 0.2 mm/yr, while the Moxi segment has the lowest average slip rate of 10.1 \(\pm\) 0.1 mm/yr. Creeping motion in the XSHFZ is concentrated between the southeast of Daofu and the northwest of Kangding, with creeping rates ranging from 1.4 to 5.1 mm/yr and depths varying between 0.5 and 3.0 km. The locking depths of the fault zone range between 13 and 26 km, with the Qianning, Kangding, and Moxi segments exhibiting higher locking depths compared to the Luhuo and Daofu segments. In the Kangding segment of the XSHFZ, kinematic deformation is allocated to three branches: Yalahe, Selaha, and Zheduotang faults. Based on the principle of seismic moment balance, the seismic hazard

of each segment of the XSHFZ was analyzed. The results indicate that the high seismic hazard areas in the XSHFZ are consistent with the distribution of seismic gaps along the fault. The Qianning segment and the Yalahe and Selaha faults in the Kangding segment, where seismic gaps exist, pose risks of earthquakes with magnitudes of 6.9, 6.9, and 6.6, respectively. It is recommended to maintain vigilance and conduct continuous monitoring of the seismic hazard in this region in the future.
