Unrest phase. (a–h) Temperature (∆T) and pressure (∆P) changes and gas saturation (\({S}_{\mathrm{g}}\)) during the unrest phase; (i–n) radial distributions of horizontal (U) and vertical (V) displacements and of gravity changes (\(\Delta g\)) on the ground surface over time (from 0.0 to 1.0 year) induced by the injection of 1485 t/d of H₂O and 726 t/d of CO₂ at a temperature of 600 °C from a 100 m-wide inlet, for two different permeability configurations, HP (left panels) and LP (right panels)
