> Abstract:
> Our understanding of subduction dynamics has its roots in earlier  
> innovative analytical and laboratory models. These early methods  
> focused on determining first order interactions between the driving  
> forces of subduction (density anomalies) and dissipative processes  
> (e.g., viscous, shear heating, bending) that resist subduction and  
> deform the slab as it sinks into the mantle. Today numerical models  
> play a special role by facilitating hypothesis testing that  
> includes such phenomena as multiple phase transitions, non- 
> newtonian viscosity, effects of grain size, water and melt.  My  
> talk will attempt to provide a historical context for the  
> scientific questions and observations driving today's models of  
> subduction dynamics, and to illustrate one way in which multiple  
> observations can be used to constrain how mantle rheology affects  
> subduction dynamics.
