Comment on 'Insights from the Mw 6.3, 2009 L'Aquila earthquake (central Apennines) to unveil new seismogenic sources through their surface signature: the adjacent San Pio Fault' by Bucci et al. (2011)

We question the approach followed by the Authors in identifying a presumed 'new' fault, and particularly the uncritical use made of topographic profiles, in which morphological features of different ages and origins are crudely correlated, creating the fake image of fault-tilting. We also point out the incorrect age attribution of faulted deposits - assumed without any analytical determination and/or stratigraphical framework - which has yielded serious errors as far as the timing of fault activity is concerned. These mistakes have led to incorrect conclusions and unavoidable repercussions for seismic hazard assessment of a region which has been just tragically struck by a disruptive earthquake.
