Temporal hydraulic and mechanical responses during experiments at different combinations of temperature and stress state. (a,b) Borehole and outlet pressures, and displacements of the pistons during triaxial compression of the sample at 400 °C under normal-faulting stress, and (c,d) the same data but at 400 °C under strike-slip stress, as functions of time.
