[CIG-SHORT] Fall AGU session - T20: Earthquake Cycle Deformation: Moving Beyond Kinematic Elastic Models

[Eric Hetland]

Please consider submitting to Tectonophysics session T20 at the AGU Fall
2009 meeting in San Francisco:

T20: Earthquake Cycle Deformation: Moving Beyond Kinematic Elastic  
Models

Description:  For the past three decades, interseismic deformation  
recorded
with Geodetic instruments has been described by the classic elastic half
space model Where deep extensions of seismogenic faults slip steadily  
at the
long-term Fault slip rate. In recent years, as geodetic data in  
deforming
regions has Become more abundant, investigators have proposed models of
interseismic deformation that move beyond the entirely kinematic elastic
half-space model. This session brings together different perspectives on
models of deformation throughout the earthquake cycle, models that
collectively are building toward a more realistic description of  
lithosphere
structure, fault geometry, and bulk and fault rheology. This evolving  
body
of work includes models that incorporate viscous flow in the  
asthenosphere,
heterogenous material properties, inelastic off-fault deformation,
frictional fault slip, and far-field driving loads. Because interseismic
deformation is intimately linked to earthquakes and coseismic slip, this
session also seeks contributions that examine models of the full  
earthquake
cycle, including earthquake nucleation and rupture, afterslip, and
interseismic fault creep. Of particular interest are studies that use
geologic and/or geophysical data to constrain models of interseismic
deformation, and studies that relate model predictions to seismicity or
measurements of long-term deformation.
