At 4 sites in Italy, a set of comparative seismic hazard estimates was performed with the aim to assess the sensitivity of each estimate to the use of different data sets. Estimates of expected average return periods for strong earthquakes have been carried out using a new approach based on probabilistic counting and logistic-type attenuation models. The different data sets used were:

the National Catalogue of Italian Earthquakes of epicentral data from 1000 until 1980 (Postpischl, 1985);

a new catalogue prepared considering all available results of recent researches on historical seismicity carried out in the framework of GNDT (National protection Against Earthquake of the National Council of Research)

data base of observed intensities compiled by the same research group.

Significant differences were found which, in particular, show the importance of observed site intensities for a reliable hazard assessment.
