G21B:
Better Living Through Volcano Geodesy: Constraints on Volcanic Hazards from Geodetic Observations and Multidisciplinary Models Posters


Submit an Abstract to this Session


Session ID#: 50032

Session Description:
Geodetic data, including both gravity and deformation monitoring, are available across a wide spectrum of spatial and temporal resolutions, and they incorporate ground-based and remote systems as well as submarine measurements.  The diversity of these observations is critical for constraining subsurface magmatic and tectonic processes that relate directly to the style and potential evolution of volcanic hazards.  Measurements of surface displacements and gravity change also inform multidisciplinary models that offer the key to forecasting volcanic activity, from phreatic explosions to Plinian eruptions.  We invite presentations focused on the development of observational geodetic techniques in volcanic environments and the integration of geodetic data with other geological, geophysical, geochemical and remote sensing results, especially in models relevant to hazards assessment and mitigation.
