| Zusammenfassung |
| We investigated the active and potentially seismogenic sources of the Lunigiana and Garfagnana extensional basins by integrating geological and morpho-structural surveys with seismological and seismic reflection data. The Lunigiana and Garfagnana basins are NW-SE grabens, originated in the hanging wall of a E-NE dipping low-angle detachment faults outcropping in the northern Tuscany Apennines. The conjugate faults bounding the basins join with the detachment at depths varying from 1 to 2.5 sec TWT, from W to E. The outcrop expression of the two fault sets is similar but the east-dipping faults show, on average, lower dip-angles (i) (30°4 km) than the west-dipping ones (50°
