Histogram of the chronology of the EUROSEISMOS earthquakes.
Over half (61%) of the earthquakes of interest for the project partners are concentrated before 1940, of which 30% in priority A, 15% in B and 16% in C.
Besides, over 33% of the earthquakes of priority interest A are concentrated before 1920, 61% before 1940 and 81% before 1960. This simple representation of the data highlights the efficacy of the project and the importance of this early reproduction phase in that it focuses on the most ancient period, whose data are rarest.
