ENVIRONMENTAL AND GEOLOGIC INDUCED RISK: A CASE STUDY IN ALCAMO MARINA (TRAPANI, SICILY)

2009

Human activities often interfere with the natural evolution of the environment, even more so when any rule or criterion of respect for the environment or urban planning is followed. This, in addition to perturb the natural system, determines conditions for geological and environmental risks, particularly when acting on vulnerable areas, poorly suited for urbanization. In the present study, risk conditions for the site of Alcamo Marina, in the territory of the town of Alcamo (TP), are analyzed, which are determined due both to the geomorphologic setting of the territory and to a large number of human interventions. carried out under an irrational approach since the 70s, in this stretch of co…

Note illustrative alla carta geomorfologica della Tavoletta Menfi (Sicilia occidentale)

2009

The present note is to describe the morphogenetic processes and the relative landforms that were recognized in the area represented by the 1: 25,000 scale IGMI topographic map named Tavoletta Menfi (Serie 25/V F. 266 IV NO). The geomorphological map was realized by using the classic methodology based on direct geological and geomorphological field surveys, integrating the acquired data with the analysis of 1:18,000 scale aerial photos taken in 1997. From the geological point of view the examined area is characterized by the outcropping of carbonate and terrigenous sediments. The great part of the territory is affected by landslide phenomena, of different sizes and activity degree, that show…

Inside The Glaciers Project: Laser Scanning Of The Grotta Del Gelo (Mount Etna, Italy)

2017

As part of activities of the “Inside the Glaciers” project, managed by an Italian team of speleologists and geologists with the purpose of studying several ice-caves in Europe and South America, a research campaign was recently carried out in Mount Etna (Sicily, Italy). This volcano is the highest active in Europe and hosts more than 200 caves including Grotta del Gelo (Ice Cave) which is located on the Northern flank of Mount Etna at an altitude of about 2040 m a.s.l. This cave was formed during the Etna’s long and most destructive eruption dated from 1614 to 1624 and is one of the most famous because it hosts a small glacier, maybe the southernmost of the Northern hemisphere. Aim of this …

The Cozzo Disi mine (Casteltermini, Sicily, Italy) a multi-disciplinary approach to record, study, preserve and develop the mining heritage in Sicily

2015

Cozzo Disi was one of the main sulphur mines in Italy, but after the closure and more than 10 years of desertion, urgent works are now necessary to save it from vandalism and flooding. This big mine contains geological and mineralogical peculiarities, so uncommon to be sometimes unique: this is the case of the “Grandi Garbere” at 3rd level, majestic karst cavities, containing magnificent selenite crystals documented by old miners. The possibility to have a “Sicilian Naica” attracted a multi-disciplinary underground task-force, now exploring the mine underground, in order to inspect old works and their good-safety conditions, and to achieve the rooms/caves of “Grandi Garbere”. This extraordi…

La Rocca di Cefalù: modello geomeccanico e condizioni di rischio per la cittadina normanna

2021

La cittadina di Cefalù, ubicata a circa 70 km da Palermo, è una delle perle del Mediterraneo, per la bellezza dei luoghi, dominati dalla Rocca, imponente rupe carbonatica alta circa 250 m s.l.m., e per i beni architettonici (Figg. 1 e 2). Fondata dai greci con il nome di Κεφαλοίδιον tra il XIV e il XIII a.C., conserva sulla Rocca il palazzo santuario ciclopico-megalitico, noto come Tempio di Diana. Sul ciglio della Rocca e per il suo intero sviluppo si snoda la cinta muraria di tipo megalitico risalente alla fine del V secolo a.C. (periodo pre-ellenico), in parte ricostruita nel periodo bizantino (VII÷IX secolo d.C.). Nel periodo normanno (secolo XII d.C.) furono costruiti i principali monu…
