Geometry and model set-up. The 2-dimensional model has an extent of 20 times 20 m. The bedding plane in this area of the Mont Terri rock laboratory has an inclination of 10°. The boundaries of the numerical model are fixed in the horizontal direction at the right side, and in the vertical direction at the bottom. The far-field stresses are given by 7 MPa in the vertical direction and 5 MPa in the horizontal direction. Initially, the model domain is assumed to be fully saturated in the whole domain, and it is assumed to remain fully saturated at the boundaries. The pore pressure in this area is set to 900 kPa
