The session focuses on the processes preceding, accompanying and following dynamic and slow ruptures. Rupture nucleation and propagation in fault zones, volcanoes, glacier systems, and landslides are governed by multiple factors including material properties, in situ stress and fluid pressure conditions, time-dependent deformation and pre-existing heterogeneities or defects. Geophysical and geological observations across fault systems at multiple scales allow to quantitatively characterize the nucleation and propagation of ruptures and to assess the thermo-hydro-mechanical properties of shear zones. At the laboratory scale, new experiments are able to investigate the 3D microstructure evolution of a deforming rock and to quantify the entire strain field. Concurrent numerical modeling efforts assist laboratory observations by unraveling the governing physical processes. Our aim is to integrate field, laboratory, and modeling investigations to address the multi-scale deformation mechanisms before, during and after major slow and fast ruptures
