We wish to invite your contributions to the following session at the AGU Fall Meeting: *Beyond the Elastic Half-Space: Understanding Volcanic Processes and Their Timescales Through More Realistic Deformation Modeling*. Please find the session details below.

However, the proliferation of available geodetic resources and complementary data, combined with advancing modeling capabilities, means that researchers can now model more realistic scenarios with the aim of better capturing the behavior of these dynamic systems. Examples include the inclusion of surface topography, variable rheology, mechanical heterogeneity within the edifice, or complex source geometries. Moreover, the combination of separate datasets (ground deformation and gravimetry, for example) has proven valuable for illuminating processes at active volcanoes, affording us better constraints on deformation source location and geometry.

Abstract: Historically, ground deformation at active volcanoes has often been modeled using simple source geometries embedded within homogeneous elastic half-spaces. However, the proliferation of available geodetic resources and complementary data, combined with advancing modeling capabilities, means that researchers can now model more realistic scenarios with the aim of better capturing the behavior of these dynamic systems. Examples include the inclusion of surface topography, variable rheology, mechanical heterogeneity within the edifice, or complex source geometries. Moreover, the combination of separate datasets (ground deformation and gravimetry, for example) has proven valuable for illuminating processes at active volcanoes, affording us better constraints on deformation source location and geometry. In this spirit, we invite contributions: - using numerical/experimental models to better fit observed ground deformation at different scales (e.g. magma storage/propagation) - focusing on sensitivities of model parameters and uncertainties - constraining model parameters (e.g. through deformation experiments) - combining discrete datasets (e.g. geodetic, geophysical, thermal) Hope to see many of you in San Francisco come December!
