Complexities of fault rupture and their implications for the joint studies of earthquake source physics and ground motion

Session ID#: 157082

Session Description:
Natural fault zones are an ensemble of multi-physics complexities, such as fault geometry, heterogeneous frictional properties and fault loading, damage zones, and fault roughness. How do natural fault zone complexities manifest on rupture dynamics and ground motion? Can we identify their specific traits, such as back-propagating fronts, rupture speed variations, spatial segmentation of slip and low/high frequency ground motion, using physical models? Given the ubiquitous near-field ground motion variability, furthermore, how should we account for the source-related physical processes in ground motion studies, targeting robust -- non-ergodic -- seismic hazard assessment? We invite all numerical, analytical, and experimental studies that address any of the above questions, with the purpose of developing a holistic understanding of the current challenges and future directions in -- deterministic, stochastic, and probabilistic -- joint studies of earthquake source physics and ground motion.
