Thermo-hydro-mechanical and chemical (THMC) processes are strongly coupled and potentially trigger earthquake events. Fluids in the subsurface can be mantle-derived, thermally decomposed by dehydration reactions, or injected for industrial applications, such as geothermics and Carbon Capture and Storage (CCS), eventually causing induced seismicity. High-pressure fluid diffusion is also often associated with various seismic phenomena, such as Episodic Tremor and Slip (ETS) Events, earthquake swarms, as well as foreshock - mainshock - aftershock sequences in different tectonic environments, including volcanic systems and subduction zones. Chemical reactions alter the hydraulic and mechanical system facilitating rock failure events. Besides the variety of observable phenomena, the underlying physical principles of fluid and heat transport, migration, and storage are similar. In this session, we want to collect novel works from (i) field observations, (ii) laboratory studies, and (iii) numerical and theoretical model development addressing the role of fluids in the earth's subsurface.
