Stochastic Simulation of Sub-Seismic Faults Conditioned on Displacement Intensity Maps

We present stochastic simulations of sub-seismic faults conditioned on displacement intensity and stress orientation maps generated from a geomechanical model. The simulations are performed in an iterative process where new faults are proposed and have a high probability of being accepted if the contribution of the new fault gives a better match with the input displacement intensity map. The algorithm is demonstrated on a synthetic test case and shows that displacement field and strike orientation of the simulated sub-seismic faults matches the pattern of the displacement intensity map and the orientation of the maximum horizontal stress from a geomechanical model.
