Comprehensive insight into coupled thermo-hydro-mechanical processes of rocks under stress is difficult to achieve, due to rock complexity. However advance in this discipline is required for a large number of problems with high socio-economic relevance.

Whether we deal with exploitation of groundwater or geothermal energy or CO2 storage or with the physics of earthquakes and volcanic eruptions, understanding thermo-hydro mechanical coupling of stressed rocks is crucial.

The study of rocks under stress can be obtained through laboratory experiments and numerical modeling from the micro to the macro scale. We invite novel contributions from laboratory experiments, numerical modeling and field work relative to the understanding of:

1. Fault structure and mechanics: from laboratory to exploratory drilling of major faults;
2. Fault healing, sealing and rupture process: observations and modeling;
3. Shear heating: experiments and modeling from frictional sliding to viscous shear heating.
4. Reservoir mechanical characterization: from geothermal stimulation to CO2 Storage and Radioactive waste disposal;
5. Rock deformation and coupled processes in rocks: observations and modeling;
6. Fracture and flow in volcanic areas and physical properties of volcanic rocks;
7. Scaling laws: from microcracks to fracture networks.
