The 1930 Irpinia earthquake, with an epicentral intensity of X MCS, is one of the largest Italian event of the XX century. It struck the north-eastern part of the Irpinia region causing the loss of about 1500 lives. The isoseismal curves (Fig. 1) trend NW-SE, such as most of largest historical earthquakes occurred in the Southern Apennines and show a weak concavity toward the SW. Large uncertainties affect the source model proposed so far due to the poor quality of the available seismological records. In this study we propose a new source model for the 1930 Irpinia earthquake based on the comparison between simulated ground acceleration field and macroseismic intensity data.
