Short summary

Considering all mapped faults in Italy, empirical scaling laws between fault dimensions and earthquake magnitude are used at the national scale. Results are compared with earthquake catalogues. The consistency between our results and the catalogues gives credibility to the method. Some large differences between the two datasets suggest the validation of this experiment elsewhere.
