Structural interpretation of geological and geophysical data available for the central Apennines (Italy) allowed us to draw, balance, and restore three geological profiles across the external zones of the Umbria‐Marche thrust system and to evaluate the timing and rates of deformation in a roughly 4 Ma time window (from late Messinian to late Pleistocene time). From this data set we established a general correlation between spacing L and thickness D of the thrust sheets (which was used as a depth correction factor for deriving local versus regional depths to the sole thrust) and a time‐space relationship between the closing time of activity of each thrust and the distance X from a reference point within the system.
