Vulnerability assessment and risk mitigation: the case of Vulcano Island, Italy
No full textThe paper reports on a comprehensive vulnerability analysis based on a research work developed within the EC ENSURE Project (7FP) dealing with the assessment of different volcanic phenomena and induced mass-movements on Vulcano Island (S Italy) as a key tool for proactive efforts for multi-risk mitigation. The work is mainly focused on tephra sedimentation and lahar hazards and related physical, systemic and mitigation capacities
APPLICATION OF THE EMPIRICAL PREDICTIVE DAMAGE MODEL OF HISTORICAL CHURCHES
No full textStrong seismic events are the main cause of serious damage to cultural heritage, especially to historical churches characterized by a lack of efficient resisting mechanisms and by high vulnerability due to their structural systems peculiarities. Their poor seismic performance is demonstrated by the recurrence of specific seismic damage mechanisms. In this paper, an empirical probabilistic damage predictive model recently presented in the literature is used to provide a scenario dependent risk assessment in a seismic prone area in Italy. In this response model, the damage is expressed by a continuous index and the seismic action is described by a scalar intensity measure. For the illustrative case study, a sample of churches falling into a limited area of Marche Region, hit by the Central Italy 2016 seismic sequence, has been chosen.
The sample includes all the historical churches belonging to the Archdiocese of Camerino-San Severino. The damage scenario following a seismic event of magnitude 5.8, generated by the Camerino fault, has been evaluated to illustrate the capability of this model in the prediction
of post-earthquake situation. Risk maps obtained by means of the method presented in the paper, can provide a notable support to the organization of post-event emergency actions and to the planning of preventive actions for the risk mitigation

No full textSubmarine Slope Failures along the Northern Sicilian Continental Margin (Southern Tyrrhenian Sea) and Possible Implications for Geo-hazard
No full textMass wasting and downslope movements are common processes that have contributed to shape the northern
Sicilian continental margin (southern Tyrrhenian Sea) since the Late Quaternary. Nevertheless, processes
controlling their evolution are still partially unknown and a variety of geologic factors can be responsible for
their formation. In this work we present an overview of the main mass wasting features (submarine canyons,
landslides, debris flows) observed and mapped in different sectors of the northern Sicilian margin. The margin is
characterized by a narrow, steep continental shelf (1-2°) and a very irregular and steep (6-8°) upper slope. The
main aims of this work are: (1) to outline the morphology of the submarine canyons and of the related mass
failure features, (2) to describe the main geological processes that control mass failure and (3) highlight their
potential implications for the geo-hazard. The study is based on Multi Beam echosounder, Side Scan Sonar data
and seismic reflection profiles, for a depth range of 20-1500 m, and on sediment samples and scattered gravity
cores, collected to define the textural and compositional properties of the seafloor. Our study focused on the
Castellammare Gulf-San Vito Trough system, the Gulf of Palermo, the Termini-Cefalù offshore and the Ustica
offshore. In the Castellammare Gulf two main channel systems converge at the San Vito Canyon. This latter
develops northwards with a very sinuous pattern, crossing the San Vito through. In the western margin of the
Gulf, where the upper slope is very steep (12-13°) and the continental shelf is very narrow or absent, there are a
lot of short, straight, sub-parallel gullies that are only few metres deep. In this sector the gully heads are located
very close to the coastline and are associated to retrogressive slides. According to the aforesaid, downward
erosive flows appear to be the most common mechanism generating widespread slope failure inside the
Castellammare Gulf. In the Palermo Gulf a difference in slope configuration can be observed between western
and central-eastern sector. Submarine canyons are confined to the upper slope or indent the shelf-edge and enter
the Palermo intraslope basin at a depth of around 1,300 m. The canyons evolved through concurrent top-down
turbiditic processes and bottom-up retrogressive mass failures. Most of the mass failure features of the area are
related to canyon shaping processes. The western sector of the Palermo Gulf slope displays a highly dissected
substrate, showing steep to very steep gradients, that appear to favour a retrogressive evolution of the canyons.
Headward erosion processes are the main controlling factor in shaping this sector. NNE trending canyons
occurring in the central-eastern sector develop in connection with the Oreto and Eleuterio rivers, breaching the
shelf break, and show a linear to sinuous thalweg path. A similar pattern can be recognized in the eastern sector
of the Termini-Cefalù offshore. The occurrence of pockmarks and carbonate mounds also suggests the probable
role that fluid seeps play in the mass wasting processes of the area. Furthermore, the occurrence of pockmarks
and highs that probably consist of authigenic carbonates above faulted and folded strata suggests a local
relationship between structural control, fluid escape processes and mass failure. In the Ustica offshore volcanism
related features (debris avalanche, gravitational collapse of volcanic edifices) are mainly linked to neotectonic
activity and volcanism that tends to build, load and steepen the submarine slopes with time. This paper presents
a valuable high-resolution morphologic dataset of the northern Sicily continental margin, which constitutes a
reliable base for evaluating the geo-hazard potential related to slope failures in the area, through monitoring of
areas where mass movement might be forthcoming and modelling landslides consequences to develop geohazard
mitigation strategies
Empirical predictive model for seismic damage of historical churches
No full textGenerally, strong seismic events cause serious damage to cultural heritage, especially in ancient churches characterized by a high vulnerability due to the intrinsic peculiarities of their structural systems which are not able to develop efficient resisting mechanisms. Starting from observed damage of churches and recorded ground motions, it is possible to define empirical response models. In this paper, an empirical predictive model for the seismic damage of churches is proposed. In particular, the damage is expressed by a continuous index and the seismic action is described by a scalar intensity measure. A sample of churches falling into a limited area hit by the Central Italy 2016 seismic sequence, which caused notable damage to the cultural heritage, has been chosen to calibrate the parameters of the proposed predictive model. The considered sample covers a wide range of damage and intensity levels, and includes all the churches of the area. The parameters of the model have been evaluated using the maximum likelihood estimation, considering a double step in the optimization procedure that combines a discrete with a continuous approach. Alternative proposals have been considered for the shape functions used in the numerical approximation and the results are discussed. Finally, the predictive model is applied to evaluate the damage scenario after a single seismic event and to illustrate the potential application of this risk analysis in decision-making processes. In particular, a deterministic event of magnitude 5.9 generated by the Senigallia fault has been considered and the consequences on historical churches reported in the national catalogue, are evaluated

Abstract
In the month of January 1900, in Verona, two washerwomen find a dismembered and incomplete body. It is Isolina Canuti, a young 20-year-old woman from a humble family, not very attractive physically, and of dubious morality. All the blame fell on the man who had been her lover and had got her pregnant: army lieutenant Carlo Trivulzio, who wanted Isolina to have an abortion. Isolina. La donna tagliata a pezzi is a realist work that grants great importance to documentation, up to the point that the author herself moved to Verona in 1983 to gather together all the necessary documents. Apart from the newspapers, she could only find silence, because the honour of the army was at stake and, what was the life of a young woman like Isolina worth against the honour of the army
