(2008) and Leonard (2010) are the most reliable one for the central Apennines and, therefore, we recommended their use together with our newly-formulated equation to estimate the seismic potential of active faults in central Italy. Results obtained by these equations show that the Campo Felice faults can produce earthquakes with maximum Mw of ~5.8 and 6.2 with single or synchronous ruptures, respectively. Finally, we performed Coulomb stress change modelling (Toda et al ., 2011) to investigate the likelihood of post-seismic stress transfer between adjacent fault segments. This modeling showed that our previous assessments can increase considering a quasi-synchronous or cascade activation of the Campo Felice faults together with nearby faults.
