Across many tectonic settings, major active fault systems commonly comprise multiple intersecting, branching or adjacent faults. High-resolution observations - including satellite geodesy, back-projection, and field data - from recent large earthquakes show that these events often rupture multiple fault segments and generate widespread off-fault damage. Over a wide range of timescales, details of the mechanical interactions between segments in complex fault systems remain challenging to untangle using traditional models of fault segmentation. Nonetheless, these interactions appear to influence the seismic and tsunami hazards resulting from complex earthquake ruptures. This session will focus on new observations, laboratory experiments, and models that illuminate how structurally complex multi-segment fault systems form and deform over geologic to seismic-cycle timescales, and how complex faulting affects earthquake cycle processes, seismicity and natural hazards for nearby communities. Submissions are encouraged from a broad range of disciplines including geology, geomorphology, seismology, geodesy, rock mechanics, and geodynamics, among others.
