Are bending-moment fault a good proxy to assess the timing of movement of underlying deeper structures? We made use of a series of sand-box experiments in order to model bending-moment faults generation and growth during progressive folding. Syn-growth sedimentation was included into the model. Our results indicated that displacement, at surface, is cumulating regularly along these structures, even when lateral propagation is inhibited, thus assuring a good reliability for the cross-section analysis of these structures (i.e. paleoseismological studies) and implying that bending-moment fault growth and associated folding could be put in relation through kinematic modelling.
From sandbox modeling to paleoseismology: preliminary results on bending-moment faults modeling.

Abstract
Are bending-moment fault a good proxy to assess the timing of movement of underlying deeper structures? We made use of a series of sand-box experiments in order to model bending-moment faults generation and growth during progressive folding. Syn-growth sedimentation was included into the model. Our results indicated that displacement, at surface, is cumulating regularly along these structures, even when lateral propagation is inhibited, thus assuring a good reliability for the cross-section analysis of these structures (i.e. paleoseismological studies) and implying that bending-moment fault growth and associated folding could be put in relation through kinematic modelling.
