Session ID#: 3361

Earthquake faulting involves physical processes operating over length 
scales which range from millimeter wide primary slip zones on the time 
scale of milliseconds to seconds during rupture, to the evolution of 
fault systems spanning hundreds of kilometers over thousands of years. 
Capturing the interaction among processes across this broad range of 
spatial and temporal scales necessitates multiscale approaches to 
numerical modeling, observations, and laboratory experiments. We invite 
submissions covering topics in this area, including earthquake 
initiation and triggering, rupture across multiple fault segments, 
effects of fault-surface roughness on source dynamics and near-field 
radiation, influence of bulk and fault rheologies on post-seismic 
deformation and slip localization, and evolution of fault zones and 
fault systems. Observational and laboratory studies that address 
multi-scale earthquake dynamics, computational efficiency, validation of 
modeling approaches, and leveraging of state-of-the-art open-source 
tools are all topics of particular interest.
