Dear colleagues,

Apologies for crossposting. 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.

Beyond the Elastic Half-Space: Understanding Volcanic Processes and Their
Timescales Through More Realistic Deformation Modeling

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

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!

Best regards,
Jamie Farquharson, Fabien Albino, and Benoit Taisne
