The geodynamic complexity of the Apennines and adjacent sedimentary basins in Umbria-Marche (North-Central&#13; Italy) makes the dynamics of the present day deformation and its relationships with the seismicity less well understood.&#13; In this paper, we argue that, further to buoyancy forces, postseismic deformation of earthquakes taking place&#13; on the Apennines contributes to the regional deformation. We investigate the interaction between the normal faulting&#13; system responsible of the 1997 Umbria-Marche earthquake sequence (Colfiorito fault) and the low angle normal&#13; faulting system bordering the sedimentary basins, namely the Altotiberina fault. We set-up a 2D finite element&#13; model of the lithosphere-asthenosphere accounting for lateral heterogeneities and investigate how this heterogeneous&#13; structure is capable of localizing strain under the Umbria-Marche sedimentary basins, providing a way for&#13; the Colfiorito fault to influence the evolution of the Altotiberina fault. We show how the two different length and&#13; time scale processes, namely postseismic deformation and buoyancy, are complementary in shaping the Apennines&#13; and adjacent sedimentary basins. The high resolution deformation patterns modeled in this study can hardly be reproduced&#13; by a model accounting only for external forces such as a rotating or subducting or retreating Adria
