A scenario-based assessment of the tsunami hazard in palermo, northern sicily, and the southern tyrrhenian sea
2020
Palermo is a populous city situated on the northern coast of Sicily, bordered by the Tyrrhenian Sea. This central part of the Mediterranean Sea features dramatic bathymetry, numerous subaqueous landslides and is also the epicentre to many subaqueous earthquakes. As such, the region is an area prone to tsunamis. This investigation uses the Cornell Multi-Grid Coupled Tsunami (COMCOT) tsunami modelling package to simulate five near-field landslides, and five near-field earthquakes regarded as worst-case credible scenarios for Palermo. The seismic simulations produced waves on a very small scale, the largest being c. 5 cm at its maximum height, and none of the earthquake-generated tsunami waves…
THE ROLE OF VOLCANIC AND ANTHROPOGENIC ACTIVITIES IN CONTROLLING THE EROSION PROCESSES AT VULCANO ISLAND (ITALY)
2011
The paper describes the erosion processes acting at La Fossa cone (Vulcano Island, Italy). La Fossa cone is a stratovolcano made up of pyroclastic deposits and lavas covered by tuffs from the last eruption, dated 1888-90. Its flanks are affected by intense water erosion phenomena leading to the formation of denudation surfaces due to sheet erosion, rills, gullies and small canyons. As a consequence of very intense rainfalls, episodic debris flows occur along main gullies and canyons. Fumarolic activity plays an important role in the control of erosion processes, being both an obstacle for the growth of vegetation and a weathering factor. The GIS analysis and comparison of geo-referenced map…

Il carsismo nei gessi della Sicilia occidentale
2018
Viene proposto un itinerario che consente di osservare alcune delle aree carsiche gessose più significative dell’intero Bacino del Mediterraneo per la eccezionale varietà e ricchezza di morfologie carsiche sia superficiali che sotterranee in esse presenti. L’itinerario si sviluppa in Sicilia occidentale e centro-meridionale e si articola in tre percorsi che possono essere realizzati in tre giorni, attraverso l’utilizzo dell’auto e tratti a piedi. Alcune delle aree, per la loro valenza scientifica e paesaggistica, costituiscono delle riserve naturali, istituite dalla Regione Sicilia, e/o Zone Speciali di Conservazione (ZSC) e Zone di Importanza Comunitaria (SIC).

Future coastal hazard scenarios. A case study in NE Sicily (Italy)
2012
The coastal dynamics is the result of several causes that contribute to change the balance of beach deposits over time. The beach system is not always able to maintain coastal balance: the factors contributing to this phenomenon are to be found in both natural and anthropogenic spheres. In this context we present the analysis of marine geology and coastal geomorphological data of a sector between Rocca di Caprileone and Tindari (north-eastern Sicily) with the aim to: i) determine their onland-offshore area relationships, ii) analyze which natural features may contribute to coastal retreat, iii) present coastal hazard scenarios. Until fifty years ago the natural balance of this coastal area …
