Time-variable Strain and Stress Rates Induced by Holocene Glacial Isostatic Adjustment in Continental Interiors Open
In continental interiors, tectonically-driven deformation rates are low, often to the point where they are undetectable with modern geodesy. However, a range of non-tectonic surface processes, particularly relating to hydrological, cryosph…
