ABSTRACT

The observation of seismic damages to archaeological sites after the 2009 earthquake in Abruzzo (Italy) has

been conducted by the Regional Directorate for Cultural Heritage and by the CNR-ITC of L'Aquila, in order

A particularly interesting aspect was the opportunity to verify the effects of the former restoration works: the

materials used have often proved to be incompatible, both from the mechanical and from the physical-

chemical point of view. The use of inadequate materials has intensified the degradation of ancient materials

(erosion and salt crystallization) and it has caused a concentration of seismic damages near the restored

areas. Those areas with a greater rigidity have almost entirely detached from old parts, causing damage to

them.

Four years after the earthquake further surveys have been carried out on a few sites that were particularly

critical conditions, in order to check the decay evolution. Among these, the amphitheater of Amiternum
