In this article, the Cultural Heritage Earthquake Damage Ontology (CHEDO) model is presented. This ontology has been designed to document damage and loss caused by earthquakes in cultural heritage, through its integration into BIM systems interconnected with databases, although this integration is not addressed in the present work. The CHEDO model integrates terms and relationships to document the damage process in relation to the building characteristics (architectural, spatial, constructional, and geometrical) and the physical environment of the same. This model, by providing a comprehensive description of the building and its environment, allows for complete and accurate documentation of damage, which supports the planning of post-earthquake restoration and reconstruction.

Este estudio presenta una evaluación simplificada para valorar la probabilidad de daños debidos a los movimientos sísmicos en los Sitios del Patrimonio Mundial de la UNESCO en toda Europa.

The conference, dedicated to museums and damage caused by earthquakes, most of whose papers are presented in this publication, was held from November 16 to 18, 2011 in Lorca.

Heritage at Risk Conference. The Lorca earthquake coordinated by the IPCE, on the effect of seismic movements on cultural heritage, in September 2011, and whose papers are collected in this publication.

The seismic evaluation of art objects requires a multidisciplinary approach and the definition of a methodology to assess the level of safety and the possible interventions necessary for the prevention of seismic risk, seeking a compromise between safety and conservation. This article describes a first step in this direction, in which the different aspects of the procedure, from the path of knowledge of the art object to the structural analysis, were studied on the six statues of Michelangelo located in the "Galleria dei Prigioni" (Slaves Gallery) of the Galleria dell'Accademia in Florence. We have shown that the general principles and criteria expressed in the "Italian Guidelines for the evaluation and mitigation of seismic risk of cultural heritage", which are specifically dedicated to masonry constructions, could be usefully extended to other works of art such as statues, starting from historical research, geometrical study and characterization of materials, to the development of specific methods of analysis. This research could be the basis for future studies on the prevention of seismic damage to art objects, including minimal interventions and specific devices, such as isolation systems.
