Abstract
Local soil conditions, roughlysummarised by considering a reference soil for eachmunicipality of the Friuli – Venezia Giulia region inNE Italy, are introduced into probabilistic seismichazard estimates: the subsequent improvement ischecked by comparing these new results and the maximumobserved intensities in each municipality toinvestigate if the major differences betweenprobabilistic estimates and actually observed data canbe explained by local site effects and/or by thegeometry of the seismogenic zones used in thecomputation. In addition, a comparison between the newprobabilistic hazard results, and the standard onesreferred to rock is made for the present and theproposed Italian seismic zonation. The resultsunderline the influence of the seismogenic model used,but are not determinant on the role of site effects.
