Description:
A seismic hazard map, with 10% probability of exceedance in 50 years in terms of macroseismic intensity, is proposed for the Italian territory.
The input elements used to evaluate the seismic hazard are: the seismogenic zoning ZS9, the earthquake catalogue CPTI04, the historical and statistical completeness. These elements are those used in MPS04 (Gruppo di Lavoro MPS, 2004).
Two new intensity attenuation models were used: 1) a set of regional relationships derived from a previous cubic model (Berardi et al., 1993) which has been recalibrated (Gómez Capera, 2006); 2) a relationship obtained with a new approach (Pasolini et al., 2006). The intensity attenuation models were obtained using the macroseismic intensity database, which was used for compiling CPTI04.
The computer code adopted to evaluate the seismic hazard, with the elements cited above, is SeisRisk III, which has been modified to be used with macroseismic intensity data, i.e. allowing to consider the normal distribution of the residuals. A logic tree approach has been used to explore some possible alternatives of epistemic character.
