Examples of anthropogenic sinkholes in Sicily and comparison with similar phenomena in southern Italy

2013

A sinkhole, occurred in June 2011 and related to an underground quarry in the eastern sector of Marsala, is described in this paper as a case study (Figure 2). The site was selected for the availability of topographic data of the underground quarry, prior to the formation of the Abstract Anthropogenic sinkholes affect several built-up areas of Sicily (southern Italy) representing a great risk to people, buildings, and infrastructures. These phenomena are generally associated with the presence of ancient underground quarries for the extraction of calcarenite rock, used for building or ornamental materials. These quarries were poorly constructed and abandoned throughout history.

The safety of an industrial archaeological heritage

2013

The present paper analyses an underground and inactive quarry of calcarenite, which belong to a localised area called Cave di calcarenite in Contrada Cuccidenna that has been recognised as a typical example of industrial archaeological heritage. The study of this typical quarry is finalised to the preservation and safe fruition of this site, which represents the history of manufacturing technologies of rocky ashlars. Rock samples from the pillars have been collected and, at first, a petrographic characterisation has been performed. The strength parameters have been estimated by means of triaxial and isotropic compression tests. Through a finite element analysis, the mechanical characterizat…
