Session Time: 4:30 PM to 5:45 PM (local time)

This session brings together researchers in geodynamic modelling and earthquake rupture modelling to exchange ideas in the areas of algorithms, software tools, benchmarks and, of course, scientific results. 
 
The timescales of interest in global geodynamics range from the overturn time of the mantle to the timescale of measurable change of plate motions. This latter timescale becomes increasingly shorter as our capacity to measure deformations reaches sub-millimetre accuracy (driven by the need to understand pressing issues in global climate change, for example). Geodynamic timescales now overlap those associated with surface relaxation times of large earthquakes. Coming from the other direction, models of earthquake rupture run over the seismic cycle and capture the long-term evolution of the surface deformation and capture the accumulated offset along individual faults. 
 
As we approach the computing power and model capacity to attempt to unify long-term geodynamic models with short timescale seismic rupture models, we propose this session to ask: What stands in our way? What algorithm developments are needed? Are there mathematical or physical scale-crossing problems that need to be overcome? Can the geodynamics and earthquake modelling community talk to each other?
