Modelled three-dimensional in situ stress state and fault reactivation risk in the Ruhr region

Abstract

This dataset presents the results of a 3D geomechanical-numerical model of the in situ stress state of the Ruhr region. The modelled three-dimensional in situ stress state is provided for each of the six components of the full stress tensor as well as for the three components of the principal stress tensor. Presented in situ stress magnitudes represent total stresses i.e., a sum of effective in situ stresses and pore pressure field accounting for the Biot’s coefficient of the rock mass. In addition to the full and principal stress tensor, scalar properties of the major fault zones located within the model volume such as shear stress, normal effective stress, Coulomb Failure Function, slip tendency, and dilation tendency are presented.
