Summary of the study by Alaskan group 1. Large uplift rates: 30 mm/yr at the maximum. 2. The observed rapid rates may not explain from the tectonic rate. 3. The uplift pattern estimated from the GPS and TG data is consistent each other in general. 4. A two-layer viscoelastic model (i.e. Elastic crust and Low viscosity half-space mantle) is not adequate to explain all three data sets of the GPS, TG and raised shore line. Three-layer viscoelastic earth model (i.e. Elastic lithosphere, low-viscosity athenosphere and high- viscosity lower mantle) is favorable to explain consistently all three data sets. 5. For the observed viscous motion to the long-term forcing, there is a possibility that the effect of post-Little Ice Age contributes.
