Fig. 8: 2D FEM models of a faulted domain that gradually reaches the conditions for failure.

a–d Progressive horizontal compression (from 10 to 20 MPa), assuming constant stiffness for the large fault segment (ELF = 1 GPa) and for the small faults (ESF = 0.03–0.92 GPa). e–h Constant horizontal compression (20 MPa) with variable large fault stiffness (ELF = 0.01–10 GPa) and constant small faults stiffness (ESF = 0.03–0.92 GPa). Models are developed with COMSOL Multiphysics (v6.2).
