Materiali per un catalogo dei terremoti italiani. Aggiornamento di studi tra gli anni 1964-1972

This paper presents the results of a review of knowledge on a dozen moderate‐energy earthquakes in the time span from 1964 to 1972. Starting from the super expeditious studies already available, the analysis of seismological sources was deepened and specific research was carried out on journalistic sources, re‐evaluating and enriching macroseismic estimates for each of the earthquakes considered. The aim of this work is to improve the overall knowledge of the earthquakes considered, the intensity data of which can contribute to enlarge the data set used for calibrating intensity‐magnitude relationships, as agreed with the CPTI15 Working Group.
