Effect of the different data survey scale on assessment of seismic exposure and vulnerability of the historic center of Caltabellotta
2019
The results of the prediction of exposure and seismic vulnerability for the buildings of the historic center of Caltabellotta, obtained with databases of different levels of accuracy, are compared. In particular, the results obtained on the basis of the estimation of the characteristics and of the distribution of the typologies derived from the filling in of the CARTIS sheets on a sector scale are compared with those obtained through a survey from the outside to a building scale. In this latter area, indicators contained in the CARTIS are suitably supplemented with those available in the literature, partly modified to adapt them to the local reality. The vulnerability is evaluated on the ba…
Placemaking in rural areas. New town Gibellina
2016
In Belice Valley, in 1968, after the earthquake, due to the generally poor life conditions, people losing their homes, and a rather not very present State, popular mobilisation was the choice. In the post-earthquake reconstruction, the self-organisation process came back in vogue due to the previous example of Danilo Dolci's action in western Sicily, during the fifties. The Mayor Ludovico Corrao also referred to the revolutionary roots of Dolci's movement, including those values in his dream of city's rebirth, involved inhabitants, artists, and architects to "make the town".
The ‘false vaults’ in the architecture of Sicily
2015
Between the end of the 17th century and the first decades of the 18th, Sicily was struck by several violent earthquakes. The total and partial collapse of monumental buildings produced a global debate involving various aspects of construction practice. One of the central topics of discussion was the construction of domes and large vaulted structures. Some architects studied the possibility of using so-called ‘false vaults’, a kind of lightweight structure created with a wooden frame, reed mats, and plaster. The technique was probably known by the 16th century and was used in a few major monuments, such as the dome of the Palermo Cathedral, in the mid-17th century. It was only after the Eart…
Prima della "Rivoluzione scientifica": uno sguardo alla ricerca antisismica nella Sicilia d'età moderna (XVI-XVIII secolo)
2021
The contribution presents and examines, through documentary readings, anti-seismic strategies and practices born with experience and with the relationship with history, selected and consolidated over time, applied in Sicilian construction from the sixteenth to the eighteenth century by architects and master builders after the great earthquakes that hit the island in the modern age.
Sistemazione in situ o musealizzazione dei frammenti architettonici: problemi di conservazione dopo il terremoto di Messina del 1908
2012
After the big earthquake of Messina in 1908, a lot of important fragments of the ancient city, coming from destroyed palaces and churches, were transported in a open space near the ancient church of SS. Salvatore, where in an old silk factory was born the actual Regional Museum of Messina. The arrangement of those elements - as Marble sculptures, big fragments of architectural decorations, stone portals - was long debated and different architects, art historians and archaeologists produced ideas and projects about the costruction of a new museum and the arrangement in open space of many fragments, so important to maintaining the memory of the ancient city of Messina, destroyed by the earthq…
Suspended territories and windows of opportunity after the 2016 earthquake in Central Italy
2019
While globalization is promoting strong economic concentrations in a few urban centres, peripheral regions are negatively affected by decreasing population and increasing impoverishment, due to the lack of policies and the failure to develop and maintain rural economies. Although natural disasters accelerate these trends, the shock created by unexpected events may generate a window of opportunity, linked both to risk-reduction processes and to transition paths towards more desirable futures. This review aims to discuss tendencies in post-disaster management in the central Apennines after the 2016 earthquake, since this shrinking rural region is slowly concluding the emergency phase and star…
Lo spazio pubblico nel post-sisma 2016-2017: mercificazione turistica e tentativi di riappropriazione dei luoghi nel caso di Amatrice
2020
La sequenza sismica che ha colpito l’Italia centrale tra 2016 e 2017 ha generato intensi processi di de- e riterritorializzazione che hanno reso il cratere un contesto privilegiato per l’analisi di fenomeni socio-territoriali. Attraverso l’analisi delle trasformazioni del territorio amatriciano nel post-sisma, si prende in esame l’impatto delle principali misure di gestione dell’emergenza e della ricostruzione, per comprendere il processo di riterritorializzazione in corso e le politiche di sviluppo sottintese. La riflessione si svolge nella prospettiva della geografia sociale, applicando alcune categorie della sociologia dei disastri. Delineato il quadro specifico della gestione emergenzia…
Testing for local structure in spatiotemporal point pattern data
2017
The detection of clustering structure in a point pattern is one of the main focuses of attention in spatiotemporal data mining. Indeed, statistical tools for clustering detection and identification of individual events belonging to clusters are welcome in epidemiology and seismology. Local second-order characteristics provide information on how an event relates to nearby events. In this work, we extend local indicators of spatial association (known as LISA functions) to the spatiotemporal context (which will be then called LISTA functions). These functions are then used to build local tests of clustering to analyse differences in local spatiotemporal structures. We present a simulation stud…
Gli ingegneri camerali in Sicilia dopo il terremoto del 1823
2016
La memoria intende indagare, attraverso lo studio delle fonti bibliografiche e soprattutto di una copiosa documentazione archivistica, il ruolo determinante svolto dalle istituzioni attraverso l’attività degli ingegneri camerali, tecnici alle dirette dipendenze dell’amministrazione regia, tra i quali emergono alcuni tra i professionisti più attivi del tempo quali Luigi Speranza, Giuseppe Patti e Alessandro Emmanuele Marvuglia. Questi ultimi vennero incaricati di effettuare numerosi sopralluoghi nelle zone colpite dal terremoto al fine di valutare e monitorare i danni, redigendo sia quadri di carattere generale relativi ai singoli centri, che perizie di dettaglio volte all’accertamento dei d…
Multi-disciplinary analysis to construct a crustal model of the Sicily Channel using geological and geophysical techniques (data): impacts on geologi…
2023
To understand the dynamics of crustal deformation and earthquakes in active orogenic systems, it is essential to have a detailed view of the lithospheric structures in three dimensions (3D). Several studies in the literature explain how 3D visualization can enable the recognition of tectonic structures or to be able to establish connections between intraplate volcanoes (Wu et al., 2016; Lei & Zhao, 2016; Tan et al., 2019). This work aims to define and discretize a 1D-velocity model of the Sicily Channel; create a detailed 3D lithospheric model of the Sicily Channel using a multidisciplinary approach to evaluate the geological hazard elements that affect the Iblean foreland integrating bathy…
