Tectonic fault zones are inherently complex systems, rarely conforming to simplistic or homogenous structural models. They are characterized by localized-to-distributed zones of brittle-to-ductile deformation accommodated across architecturally complex shear zones, fault cores, and slip surfaces with variable frictional, rheological and material properties. Such complexities and heterogeneities play a fundamental role in controlling the full spectrum of earthquake rupture processes, including nucleation, propagation, arrest and post-seismic deformation, including afterslip. This session will showcase recent interdisciplinary advances that enhanced our understanding on how fault zone complexity influences earthquake rupture dynamics. We welcome contributions covering a broad range of approaches, including geodetic measurements of fault creep and slow-slip, in-situ field experiments, and seismic field observations. Submissions employing laboratory experiments, theoretical analyses and numerical modeling are encouraged. By bringing together diverse methodologies and perspectives, this session seeks to advance our understanding of the mechanisms governing earthquake initiation and rupture evolution in complex fault zones.
