We have developed a new glacial isostatic adjustment (GIA) model, RF3L20(β=0. 4) +ICE-4G, which is well constrained by geodetic measurements, relative sea levels and shear-wave seismic tomographic data. Based on this model we will show how GIA affects the secular rate of change of gravity and sea level in East Asia. An advantage of this model is that the viscosities in the mantle are allowed to vary both in the radial and lateral directions. The laterally homogeneous reference viscosities are given by model RF3 (modified from Peltier' s VM2). Lateral viscosity perturbations are converted from seismic tomographic data using the well-known scaling relationship multiplied by the factor β. The latter is used to quantify the contribution of thermal effect to lateral variation in shear wave velocity, and is chosen to be 0. 4 by fitting the GIA data. In addition, the deglacial phase of the ice loads is given by the ICE-4G model. We assess the uncertainties of the GIA predictions by considering the differences between two reference viscosity models and two ice models. The GIA predictions are computed using the coupled-Laplace Finite-Element Method. The results show that GIA has obvious effects on the secular rate of change of gravity and sea level in East Asia. For example, the GIA effect on gravity can be several tens of nGals per year which can be detected by superconducting gravimeter and future atomic gravimeters at the geodetic stations Harbin, Changchun, Taian, Jixian, Zhengzhou and Wuhan. Also GIA is estimated to contribute 3 %~10 % on the secular trends of equivalent water heights on land in East Asia. The larger GIA effect appears in the west Tibetan Plateau, North China and Three Gorges Area. From East China Sea to the Pacific Ocean, the relative effects of GIA can be 20%~40%. GIA has caused a long-term depression of the absolute sea level in the ocean area by 0. 27~0. 37 mm/a. For the secular change in absolute sea level measured by satellite altimetry, the GIA effects can be 6. 9% and 7. 5% in Yellow Sea and East China Sea respectively. For the 58 tide gauges, the average value of the observed long term RSL rate is 2. 22 mm/a while the GIA effect is -0. 17 mm/a and the relative effect is 8. 3%. For the 14 gauges, the GIA effects are -0. 3~-0. 4 mm/a. Therefore the results of this paper provide useful GIA corrections, so that the weak signals from geodynamic processes in the East Asia can be revealed.
