Table 2: Velocity of Sichuan reference station (Unit: mm/y). Figure 6: Movement rate of the Sichuan regional reference stations in the (**a**) horizontal direction and (**b**) vertical direction. Figure 7: Distribution of annual change rate of Sichuan regional baseline in (**a**) N Component; (**b**) E Component; (**c**) U Component; (**d**) L Component, respectively. The bolded baseline indicates that the annual rate of change of the baseline is negative, showing a shortening trend; the unbolded baseline has a positive annual rate of change, showing an extension trend. \begin{table}
