G43A:
Geodetic Measurements of the Earth's Elastic Response to Surface Mass Variability II


Submit an Abstract to this Session


Session ID#: 57901

Session Description:
The elastic response of the Earth’s crust to surface mass variations results in deformation and stress changes that are resolvable with advanced modeling techniques. Modern geodetic tools, such as GPS, InSAR, and Gravimetry, can measure the effect of lithosphere 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 of surface deformation using loading theory and the resulting stress changes from mass movement on land, ocean, cryosphere, and atmosphere. This includes, but is not limit to, studies that calculate surface 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 to investigate loading processes, decipher elastic and non-elastic signals, refine Earth structure models, or discuss correlation between surface deformation and seismically inferred stress changes in the crust.
