Induced earthquakes triggered by oil and gas production, enhanced geothermal systems, fluid injection for mining and carbon capture have raised significant concerns. The spatial and temporal evolution of induced seismicity is intricately connected to multiple factors, including the poroelastic response of the site, fluid budget, duration of operations and halts, dimension and hydromechanical properties of the substratum, and fault-slip modes under undrained/drained conditions. These factors vary between nonproducing unconventional reservoirs and porous conventional reservoirs. The spatiotemporal progression of induced earthquakes appears closely tied to pre-existing tectonic structures, the orientation of faults, the diffusion of pore pressures, stress redistribution over time and poroelastic stress transfer. Multidisciplinary approaches can help to unravel underlying mechanisms, thereby, providing insights into the development of multifaceted mitigation strategies.
We invite submissions of case studies that offer insight into the underlying physics of induced earthquakes and the dynamic evolution of stress on host faults. We encourage interdisciplinary studies showcasing source properties of induced earthquakes, 3D imaging of faults, numerical simulations, stress field modeling, InSAR modeling, ground motion prediction models tailored for induced earthquakes, and integrated hydrologic and geo-mechanical modeling linked to production/injection operational data. We welcome contributions that delve into innovative datasets such as deep learning, distributed acoustic sensing and large-N arrays. We also seek computational, laboratory and in-situ experiments to unravel hydromechanical processes governing triggering mechanisms over time.
