318 GNGTS 2016 S essione 2.1 the dimensions of the faults) for the zone, increased of its standard deviation. Mmax2 is assumed conservatively equal to Mmax1+0.3. A weight of 0.5 is applied to each branch. To compute the preliminary hazard results, the Akkar et al. (2014) GMPE was applied, both using the Joyner-Boore and hypocentral distance versions. A strict comparison with the values of the previous Italian seismic hazard map [MPS04: Gruppo di Lavoro MPS04 (2004); Stucchi et al. (������� ����� �� ������� �� ��������� �� ��� 2011)], which is assumed as reference by the Italian building code, is not possible because the two maps use different earthquake catalogues Fig. 3 – PGAwith a 475-year return period: a) original MPS04; b) A1 zonation (J&B distance, Akkar et al. , 2014) ; c) A1 zonation (hypocentral distance, Akkar et al. , 2014); d) original SHARE.
