MULTISCALE DYNAMICS OF EARTHQUAKE FAULTING
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.
