Induced seismicity refers to earthquakes and seismic events that are directly or indirectly triggered by human activities that alter the state of stress or pore-fluid pressure in the Earth's crust. Key drivers include fluid injection or withdrawal (e.g., wastewater disposal, geothermal operations, hydrocarbon production), reservoir impoundment, mining, and underground construction. These activities modify effective normal stress on faults, potentially bringing pre-stressed fault segments to failure according to Coulomb failure criteria. Research focuses on characterizing fault activation thresholds, spatiotemporal patterns of seismicity, scaling relationships with operational parameters, and developing probabilistic hazard models and operational protocols (“traffic light” systems) to manage and mitigate seismic risk.
