ABSTRACT Flexure in pro‐foreland basins results from the interplay between (sub)surface loading, foreland plate strength, inherited crustal architecture, and degree of coupling. It is expected that lateral variations these controlling mechanisms will result along‐strike flexural profile basin. This directly influence position width forebulge, thereby altering associated extensional stress field space time around which syn‐flexural normal faults accommodate deformation. As such, spatiotemporal growth may provide valuable information regarding evolution an orogen‐foreland basin system. However, relation fault flexure remains underexplored. Here, we quantify vertical throw distributions for strata German Molasse Basin. allowed us to develop a 4D model. Our indicate was with both nucleation new selective reactivation pre‐flexural faults, latter depending on burial depth at onset flexure. Furthermore, our suggest localisation strain deformation top European during controlled site Molasse. Additionally, variation activity suggests northward migration rate 7.8 mm/year consistent previous estimates based other independent methods. Lastly, west‐to‐east increase cumulative offsets down‐dip Basin have been by orogen‐parallel lithospheric strength downgoing plate.
