GOMEZ C, Augusto A. SEISMIC HAZARD MAP FOR THE ITALIAN TERRITORY USING MACROSEISMIC DATA. Earth Sci. Res. J. [online]. 2006, vol.10, n.2, pp.67-90. ISSN 1794-6190.

A seismic hazard map, in terms of macroseismic intensity, is proposed for the Italian continental territory and Sicily, which has a 10% probability of exceedance in 50 years. The methodology used here was first proposed by Cornell (1968), which requires information about the location and seismicity rates within each of the defined seismogenic zones, as well as an attenuation model. In particular, it is proposed an original macroseismic intensity attenuation model derived from the Italian macroseismic database DBMI04. The seismic hazard map, obtained in terms of intensity, was subsequently transformed into PGA by means of a linear relation between intensity and PGA, in order to compare it with the national seismic hazard map MPS04.
