Narrowest inlet and higher permeability in the conduit. (af) Temperature (∆T) and pressure (∆P) changes and gas saturation (\({S}_{\mathrm{g}}\)) during the unrest phase; (gl) 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 5 m-wide inlet. The unrest phase was simulated for the permeability configurations HP (left panels) and LP (right panels) after increasing the permeability of the central conduit FC by two orders of magnitude
