GPS Monitoring of the Scopello (Sicily, Italy) DGSD Phenomenon: Relationships Between Surficial and Deep-Seated Morphodynamics
2015
The Scopello area, which is located along the north-western Tyrrhenian coastal sector of the Sicilian chain (Italy), is widely affected by Deep-seated Gravitational Slope Deformation (DGSD) phenomena, which are mainly the result of a geomorphologic setting marked by the outcropping of an overthrust plan, limiting a brittle fractured carbonate slab, laid onto a ductile marly-clayey substratum. Due to the very advanced stage of the deformation phenomena, a coupled morphodynamic style has established between shallow landslides and DGSD phenomena, affecting the exhumed ductile substratum and the overlaying rigid dismantled slab, respectively. A GPS network was realized for monitoring the Scopel…
Evaluation, Analysis and Perception of Sustainable Forest Management Through the Lens of the PEFC Forest Certification Using Two Case Studies in Sici…
2019
Sustainable forest management has reached a common understanding between scientific and technical definitions. A series of criteria and indicators have been implemented for monitoring the effectiveness of the management in functional and structural terms, and to evaluate its effects on ecosystem services of forests. Currently, Sicily has no forest areas with certification of sustainable forest management and in order to evaluate the diffusion of knowledge of certification schemes and their importance in SFM, a questionnaire survey was carried out during a foresters' workshop on the island. The possibility of applying the criteria and indicators of PEFC certification of sustainable forest ma…
ESPLORANDO IL MEDIOEVO: HENRY GALLY KNIGHT E LA SICILIA
2018
This essay is dedicated to the figure of Henry Gally Knight, a well-known british expert of medieval architecture, who decided to reach Sicily in 1836 to complete his Norman architecture investigations, together with the architect George Moore. During his stay in the island, besides visiting more traditional landmarks of classical antiquity, Gally Knight’s specific interests will lead him not only to study prestigious architectural complexes like Monreale and Cefalù, but also to trace the medieval vestiges even of the island’s inner parts, such as Randazzo, Maniace, Troina. Gally Knight’s tour and the esulting volumes he published – The Normans in Sicily: being a Sequel to “An architectural…
Investigating the Effects of Cell Size in Statistical Landslide Susceptibility Modelling for Different Landslide Typologies: A Test in Central–Northe…
2023
Optimally sizing grid cells is a relevant research issue in landslide susceptibility evaluation. In fact, the size of the adopted mapping units influences several aspects spanning from statistical (the number of positive/negative cases and prevalence and resolution/precision trade-off) and purely geomorphological (the representativeness of the mapping units and the diagnostic areas) to cartographic (the suitability of the obtained prediction images for the final users) topics. In this paper, the results of landslide susceptibility modelling in a 343 km2 catchment for three different types of landslides (rotational/translational slides, slope flows and local flows) using different pixel-size…
Multi-temporal tectonic evolution of Capo Granitola and Sciacca foreland transcurrent faults (Sicily channel)
2019
Highlights • Seismic reflection profiles evidence tectonic inversion and active strike-slip faults offshore SW Sicily foreland • Pliocene-Quaternary transpressional inversion of Late Miocene extensional basins • Transpressional fold growth rates were high in Latest Miocene-Pliocene and decreased during Quaternary Joint analysis of high-penetration multi-channel and high-resolution single-channel seismic reflection profiles, calibrated by deep well boreholes, allowed a detailed reconstruction of the Late Miocene to Recent tectonic history of the Capo Granitola and Sciacca fault systems offshore southwestern Sicily. These two fault arrays are part of a regional system of transcurrent faults t…
Sea Surface Temperatures and Paleoenvironmental Variability in the Central Mediterranean During Historical Times Reconstructed Using Planktonic Foram…
2019
The ongoing anthropogenic‐induced warming assessment requires a robust background from regional sea surface temperature (SST) reconstructions. Planktonic foraminifera have yielded valuable insights into late Quaternary SST dynamics, but the techniques to estimate SST from fossil assemblages have only rarely been used in very recent sedimentary records (the last 2,000 years). Here we use two transfer function methods, modern analog technique and artificial neural networks, to reconstruct SST variability in two cores from the Central Mediterranean Sea that span the last five centuries. Both cores show similar and considerable changes in the planktonic foraminifera assemblages. However, the in…
Le fondazioni dei frati predicatori in Sicilia tra XIII e XVIII secolo: un primo bilancio storiografico
2021
The historiographical literature dedicated to the architecture of the Friar Preachers in Sicily, if one excludes the few studies on the complexes in Palermo, which are anyhow focussed on the churches only, is still substantially limited to the sporadic studies by local scholars or members of the Order on the history of the Dominicans in Sicily. The aim of our research, therefore, was to outline a general framework that could serve as a stepping stone for further research. It was first of all necessary to carry out a census of all the Dominican architectural complexes in Sicily, in order to determine the overall dimensions of the phenomenon and its chronological and territorial articulation,…
APPLICAZIONE DI CRITERI E INDICATORI DELLA CERTIFICAZIONE PEFC DI GESTIONE FORESTALE SOSTENIBILE: DUE CASI STUDIO A CONFRONTO NEL TERRITORIO SICILIANO
2018
Sicily currently has no forest areas with certification of sustainable forest management. This work analyzes the possibility of applying the criteria and indicators of PEFC certification of sustainable forest management in two study-cases: the municipal forest of Bivona (AG) and a forest area in the Madonie Mountains (PA). Both are representative of different and important Sicilian forest ecosystems. This analysis highlights the main weaknesses related to current forest management practices and the inadequate consultation with stakeholders.
Geohazard assessment of the north-eastern Sicily continental margin (SW Mediterranean): coastal erosion, sea-level rise and retrogressive canyon head…
2022
Coastal dynamics are the result of several processes controlling the balance between sediment input and output over time. The beach system is not always able to maintain a neutral coastal balance due to natural and anthropogenic causes. We present an integrated marine geology, geomorphological and sea-level rise analysis in the coastal sector between Torre delle Ciavole and Capo Calavà (North-Eastern Sicily, Italy).This sector is characterized by high uplift rates and frequent seismicity (mainly generated by the very active Vulcano-Tindari Fault System), promoting the development of mass-wasting processes in the coastal and offshore sectors. A main erosive feature observed in the area is th…
Granulometry, mineralogy and trace elements of marine sediments from the Gulf of Milazzo (NE Sicily): evaluation of anthropogenic impact
2010
Granulometry, mineralogy, and trace element concentrations are determined in marine sediments from thirty-six sampling sites in the littoral environment of the Gulf of Milazzo (NE Sicily). Sediment samples were collected in August 2008, along 18 seaward transects, at water depths of ‐10, ‐20 and ‐30 m, by using a Van Veen grab. Grain-size analysis shows predominance of sand (56%) and silt (35%) fractions with respect to clay (7%) and gravel (2%) fractions. Bulk mineralogical analysis documents the presence of quartz, micas, feldspars, calcite, and chlorite, which reflect erosion processes affecting the Kabilian-Calabrian Units. Concentrations of most trace elements in the deeper sediments w…
