In this study, we investigate the present-day crustal uplift in the TP using geodetic observations, including Global Navigation Satellite System (GNSS) and precise leveling. A hydrological load deformation model is formulated by integrating the Gravity Recovery and Climate Experiment and Follow-On (GRACE/GFO) satellite gravity with a surface hydrological fusion model. Tectonic-induced VLM is calculated after correcting for surface elastic deformation, geocentric motion (-0.1 to -0.2 mm yr-1) and glacial isostatic adjustment (0.3 to 0.4 mm yr − 1 ). The comprehensive VLM imaging and dynamic tomography reveal significant crustal uplift in the southern and northeastern TP, with uplift rates up to 2 mm yr-1, primarily attributed to plate compression. The northern and southeastern TP exhibit complex vertical tectonic movements, potentially influenced by block extrusion and mid-lower crustal flow.
