Summary of the results




Faulting under moderate to high tectonic loading
Using our multiscale cellular automaton model, we underline different phases of during the
formation and evolution of a population of faults under a low tectonic loading,

Other phases such as are more obvious during the

formation and evolution of a population of faults under a high tectonic loading.


Faulting under rotating conditions
o a. Temporal variations
Here, we present the formation and the evolution of fault populations according to a permanent rotation of
the orientation of the tectonic loading. This external loading is uniform across the entire domain. As shown in

formation and the evolution of a population of faults under rotating condition,

the reorganization of fault networks involves


o b. Spatial variations
Here, the tectonic loading does not evolve temporally but spatially following the North-South direction. As shown in

formation and the evolution of a population of faults with non uniform orientation of the tectonic loading.

We distinguish


Interaction between different faulting mechanisms
Here, we study the interrelated evolution of conjugate strike-slip fault.
