How is deformation accommodated in structurally-immature, discontinuous fault zones? Strain accommodation is rarely limited to kinematically and/or geometrically homogeneous fault segments, and often involves strain partitioning between systems of faults that work together to release seismogenic strain. This is especially true in young or structurally immature zones such as fault tips, stepovers, transfer zones, fault relays, or other along-strike discontinuities, but may also occur on mature faults. Deformation in these zones is also often spatially or temporally variable over multiple earthquake cycles, challenging our seismic hazard assessments. We invite contributions that aim to characterize these complex zones, including the spatiotemporal expression of slip, both at depth and at the surface. Approaches from neotectonic mapping, paleoseismology, geodesy, modeling, and novel techniques are welcome.
