Constraining maximum event magnitude during injection-triggered seismicity
Understanding mechanisms controlling fluid injection-triggered seismicity is key in defining
strategies to ameliorate it. Recent triggered events (eg Pohang, Mw 5.5) have exceeded …

[HTML][HTML] Permeability evolution of fluid-injection-reactivated granite fractures of contrasting roughnesses
Fracture/fault instability induced by fluid injection in deep geothermal reservoirs could not
only vary the reservoir permeability but also trigger hazardous seismicity. To address this …
