in Southern Italy (in the Irpinia region). Starting from the source models proposed in different studies, we have simulated
the acceleration field for each hypothesized model, and compared it with the macroseismic data. We then
used the hybrid stochastic-deterministic technique proposed by Zollo et al. (1997) for the simulation of the ground
motion associated with the rupture of an extended fault. The accelerations simulated for several sites were associated
with the intensities using the empirical relationship proposed by Trifunac and Brady (1975), before being compared
with the available data from the macroseismic catalogue. A good reproduction of the macroseismic field is
provided by a normal fault striking in Apenninic direction (approximately NW-SE) and dipping 55° toward the SW.
