Earth-flow susceptibility assessment in the Marvello River basin (Sicily, Italy)
2014
In this study, statistical models of earth-flow susceptibility were prepared using logistic regression. The analyses were carried out in a small (51 km2) basin of western Sicily, where 1,376 earth-flows were identified. To predict the spatial distribution of the mapped landslides, outcropping lithology and seven topographic attributes were exploited as explanatory variables. Before calculating these variables, a reconstruction of the pre-failure topography was performed. To evaluate the predictive skill and the robustness of the models, two groups made of five random subsets of earth-flows and stable cells were prepared. Absences of the first group were selected as individual cells whereas …

Identification and assessment of geosites for territorial enhancement – the study and geoheritage exploitation of the Torre Salsa natural reserve (Si…
2014
The “Ecological Cross-‐border Networks Malta-‐Sicily” (RE.MA.SI.) is an international research project founded by the Italia-‐Malta 2007-‐2013 Programme. A part of the project aims to carry out a multidisciplinary study for the identification and enhancement of geosites in the Maltese Islands and Sicily. Some areas have been picked out; these areas are spectacular and interesting for the tourists and can make a significant contribution to the understanding the geological and geomorphological history. Field surveys took place for the identification and classification of the most significant geomorphosites and the verification of the collected bibliographical data; in particular, the iden…
Bridging Malta and Sicily through geoheritage exploitation: Identification and assessment of geosites for territorial enhancement
2013
Malta and Sicily show common geological and geomorphological features, having been also physically linked not later than the Last Glacial Maximum. At present both islands have a high tourist vocation, but their environmental potential is not fully exploited for attracting tourists and visitors. In the framework of an international research project, “Ecological Cross-border Networks Malta-Sicily” (RE.MA.SI.), a multidisciplinary study for the identification, selection and enhancement of geosites in the Maltese and Sicilian islands was carried out. A number of sites both in Malta and Sicily have been identified and qualitatively and quantitatively assessed applying a methodology already teste…
Recenti indagini sul sistema carsico di Sant’Angelo Muxaro (Sicilia Centrale)
2015
Il sistema carsico di Sant’Angelo Muxaro si sviluppa in corrispondenza del rilievo gessoso su cui sorge l’abitato omonimo, nel centro Sicilia, in provincia di Agrigento. Tale sistema è costituito da due inghiottitoi attivi (Grotta di Sant’Angelo Muxaro o localmente Grotta Ciavuli e Inghiottitoio Infantino), che si aprono al termine di due valli cieche alla base del versante meridionale del rilievo, e da una risorgenza attiva, ubicata alle pendici del versante nord-occidentale dello stesso rilievo. Le prime esplorazioni speleologiche e l’attività di ricerca in questo sistema nei gessi messiniani della Sicilia, escludendo le segnalazioni del geografo Olinto Marinelli, sono cominciate tra la f…
Multi-parametric GIS analysis to assess gully erosion susceptibility: a test in southern Sicily, Italy
2011
: A GIS-analysis was carried out in a test basin of southern Sicily, the Magazzolo River basin, in order to assess susceptibility conditions to gully erosion phenomena. The linear density of ephemeral and permanent gullies computed within each class of nine environmental variables was used to generate a gully erosion susceptibility map for the area. A validation procedure carried out in order to test the reliability of the adopted method highlighted a clear correlation between the occurrence of gullies and the computed susceptibility levels
