abstract = "{Active tectonic movements and surface deformation are observed in the
eastern Tibetan Plateau. Understanding variations in crustal
thickness and the deep Moho interface is crucial for elucidating
the expansion of the Tibetan Plateau. This study utilizes InSAR
to derive vertical surface deformation and applies loading
corrections based on Green's function method. Additionally,
satellite gravity data are used to separate hydrological and
tectonic signals to infer changes in the Moho interface. Our
results indicate that the regionally averaged loading effects,
estimated using localized Green's functions, account for
approximately 16.5 per cent of the InSAR-derived vertical
displacement field. This contribution exhibits significant
spatial variability, exceeding 100 per cent in regions with
strong hydrological activity. The loading calculation is highly
sensitive to Earth model: the relative difference between the
load displacement obtained using the local Green's function and
that obtained with an average Green's function reaches 48.2 per
cent. After applying loading corrections, a more accurate Moho
uplift rate of 8.2 {\ensuremath{\pm}} 3.1 mm a$^{-1}$ is
obtained. The findings support the conclusion that the Moho
interface rises in the southern region of the study area, with
crustal thinning, while the Moho surface sinks in the northern
region, with crustal thickening.}",
