I terremoti in Sicilia dall'anno 1000 al 1968: uno studio analitico e statistico

The historical data about 624 Sicilian earthquakes from the year 1000 up to 196S have been accurately studied and scientifically interpretated. 248 of them, with I > VII, or .1/ > 4.6 are plotted on the epicenter map. Their corresponding approximated magnitude have been calculated with the help of an experimental curve plotted by means of some of them. With such calculated magnitude, a statistical study has been carried out:
