Fig. 3: Workflow describing the two main steps of our approach.

The approach includes1 model setup and a constraint on model parameters through geophysical imagery and field observations, and2 stochastic approach for which the simulated topography is compared with the topography of terrace treads extracted from a very high-resolution digital elevation model. This approach yields posterior information on the fault geometry and height of pre-deformed alluvial deposit. The obtained cumulative displacement is combined with age constraints to derive fault slip velocity.
