Seismicity and Crustal Structure in the Italian Region: A Preliminary Zoning

  • Roberto Cassinis
Part of the Ettore Majorana International Science Series book series (PRIP)


The transitional area of Italy is a very complex one, the relationship between seismicity and crustal structure being complicated by the geological history of the more general collision between Eurasian and African plates.

The final objective of the investigation is to analyze the elements of instability in order to use them as weighted parameters for the definition and classification of the earthquake origin zones.

The phase of the survey illustrated in this paper consists in the preparation of a preliminary zoning, in the determination of the average values of the available parameters for each zone and in the comparison between the major units as far as the character of the seismicity and the structural type is concerned.
