Dear Colleagues, the following session at EGU in Vienna might be of interest to you. The topic is at the focus of growing international interest on hazard-related physical processes. We hope to see as many of you there to share your research and create opportunities for future projects. With Best Regards Sergio, Stefan, Philip and Federico *Thermo-hydro-mechanical coupling and physical properties: implications for natural hazards* http://meetingorganizer.copernicus.org/EGU2016/session/20103 EMRP1.5/GMPV5.15/NH3.21 Convener: Sergio Vinciguerra Co-Conveners: Stefan Nielsen , Philip Benson , Federico Agliardi 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. In particular, a good understanding of the physical role of the temperature in the deformation processes is of crucial importance for crustal deformations. 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 and frictional processes: experiments and modeling, 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
