Abstract
[4] The conclusions of the paper are not changed: The endothermic character of the decarbonation reaction limits the co-seismic temperature increase; decarbonation is a source of CO2 that significantly increases the slip-weakening effect of thermal pressurization; the pore fluid pressure exhibits an initial phase of increase due to thermal pressurization, then a sudden acceleration of generated pore pressure when the solid decomposition is activated. The increase of permeability limits the pore pressure that reaches a maximum and then decreases. The numerical results reproduce this pore pressure pulse and the initial fault weakening followed by a restrengthening of the shear stress.
