Earthquake catalogue
Italian seismicity is well described by historical chronicles, reportage,
manuscripts, and so on, due to the rich cultural tradition and history of the
country. Among the most complete catalogues available in Italy for this study we
selected the Camassi and Stucchi (1996) catalogue, because it was specifically
assembled for hazard studies. In fact this catalogue contains only mainshocks
and the events are associated to the seismic source zones in Figure 8.1. The
seismicity is described by the epicentral intensity and the surface wave
magnitude.
The catalogue lists earthquakes that occurred in Italy from AD 1000 to 1980;
we updated the catalogue up to 1996, adding earthquakes above magnitude 4.6
contained in the instrumental catalogue of the National Institute of Geophysics.
The resulting catalogue consists of 2028 earthquakes relevant for Italy
distributed over the 81 seismic source zones and 150 earthquakes belonging to a
