Natural hazards events such as earthquakes or volcanic eruptions involve activation of coupled thermo-hydro-chemo-mechanical processes in rocks. Understanding these dynamic coupled processes is therefore of key importance in elucidating our comprehension of earthquakes and volcanic unrests and essential for the mitigation of seismic and volcanic hazard.
Rock physics experiments and numerical models can help us to understand and constrain the mechanisms of natural hazards from the micro to the macro scale. We invite novel contributions based on laboratory experiments, numerical modeling and field work (or a combination of these) relative to the understanding of:

1) Fault evolution in the interseismic period, including healing, and sealing processes,
2) Rupture processes: experiments and modeling from frictional sliding to viscous shear heating.
3) Rock deformation and coupled processes in rocks,
4) Fault structure and mechanics, from the field and laboratory to exploratory drilling of major faults,
5) Fracture and flow in volcanic and geothermal areas and the physical properties of volcanic rocks
