The advancement of subsurface energy technologies for fluid injection/extraction has resulted in a rapid increase in induced seismic events since 2008. While fluid pressure changes and the resulting stresses have been identified as responsible for induced earthquakes, several mechanistic issues are still debated, including how events are triggered at large distances/depths, the role of static/dynamic stress transfer, the role of hydro-chemical reaction driven by injected fluids, the role of aseismic slip, and what geological and stress conditions determine/limit the maximum induced earthquake size. We invite contributions that focus on understanding these mechanistic issues, developing new predictive capabilities, or presenting relevant field/laboratory observations, including (1) multiphase flow and coupling processes (e.g., poroelastic, thermal and chemical), (2) geomechanical modeling from fracture to reservoir scales, (3) geological/hydrological parameters and heterogeneity, (4) elastic loading, stress transfer processes and aseismic deformation, and (5) the influence of tectonic stressing, proximity to failure and fault orientations.
