The Earth’s crust elastic response to surface mass variations results in deformation and stress perturbations that are resolvable with geodetic measurements and modeling techniques. Modern geodetic tools, such as GNSS, InSAR, and gravimetry, measure the effect of lithosphere deformation with high-accuracy. This session incorporates geodesy’s applications to hydrology, cryosphere, seismology, and solid-Earth studies. We invite presentations that bridge geodetic observations of deformation using loading theory and the resulting crustal stress changes from mass movement on land, ocean, cryosphere, and atmosphere. Topics include, but are not limit to, studies that calculate deformation with numerical models, or acquire independent loading data, and compare with the geodetic measurements. In particular we welcome presentations using geodetic deformation measurements at the local- to global-scale that investigate surface loading processes, thermoelastic models, decipher elastic and non-elastic signals, improve Earth structure models, or present correlations between surface deformation and seismic activity inferred stress changes in the crust.
