316 GNGTS 2022 Sessione 2.2 (1) (2) Results. Fig. 1 shows the (M w – R) scenarios computed using the BMSE for a return period of 475yr, for the three sites selected as reference: Milano, Bologna and L’Aquila. The sites are Fig. 1 - Best fitting earthquake scenarios, in terms of magnitude M w and distance R epi , for three sites of the Italian territory: Milano, Bologna and L’Aquila. The plots on the left show the position of the site with respect to the seismogenic sources of the ZS9 model used in the MPS04 SH analyses. The numbers are the maximum magnitudes associated to the seismogenic sources. The circles show the scenario epicentral distances R epi . The plots on the right show the best fitting (M w – R epi ) spectrum (red dashed lines) together with the corresponding UHS target (grey solid lines). All the results refer to a return period of 475 years and an ε value of 0.
