Geosystems represent a major strategic resource for the ongoing transition toward cleaner and carbon-free energy production and waste management. Energy production and waste storage in geological media often involve complex multiphysical processes in the porous fractured rock, where changes in pore pressure, temperature and strain of the solid skeleton are superposed to chemical reactions. Such processes commonly induce microseismicity and in some occasions induce large magnitude earthquakes that are perceived by the local population and may damage the infrastructure. Understanding and predicting the processes that induce seismicity require integration of advanced experimental, analytical and numerical approaches that describe coupled thermo-hydro-mechanical-chemical interactions. Applications include (but are not limited to) carbon capture and storage (CCS), geothermal energy, gas storage, stimulation strategies, hydro-fracturing/shearing and radioactive waste storage. In this session, we welcome contributions that advance the understanding of triggering mechanisms of induced seismicity and present novel methodologies to forecast fluid injection induced seismicity.
