The architecture of mountain belts evolves in space and time, essentially through the formation of faults and shear zones that are active at different depths in the lithosphere. Tectonic faults and shear zones accommodate orogenic deformation through a combination of long-term aseismic creep and short-term seismic slip across a wide range of spatiotemporal scales, and of stress, pressure, temperature, and fluid conditions. Understanding what governs the short- and long-term rheology of faults and shear zones is central to the geodynamics of mountain belts, as well as to the assessment of their seismic potential. The session welcomes contributions from geological, geophysical, experimental, and modelling studies that explore the underlying rheology controlling different deformation styles and seismicity in orogenic belts, bridging the gap across different spatial and temporal scales of observations.
