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