An Integrated Multiscale Method for the Characterisation of Active Faults in Offshore Areas. The Case of Sant’Eufemia Gulf (Offshore Calabria, Italy)
2021
Diagnostic morphological features (e.g., rectilinear seafloor scarps) and lateral offsets of the Upper Quaternary deposits are used to infer active faults in offshore areas. Although they deform a significant seafloor region, the active faults are not necessarily capable of producing large earthquakes as they correspond to shallow structures formed in response to local stresses. We present a multiscale approach to reconstruct the structural pattern in offshore areas and distinguish between shallow, non-seismogenic, active faults, and deep blind faults, potentially associated with large seismic moment release. The approach is based on the interpretation of marine seismic reflection data and …
Shared language, diverging genetic histories: high-resolution analysis of Y-chromosome variability in Calabrian and Sicilian Arbereshe.
2015
The relationship between genetic and linguistic diversification in human populations has been often explored to interpret some specific issues in human history. The Albanian-speaking minorities of Sicily and Southern Italy (Arbereshe) constitute an important portion of the ethnolinguistic variability of Italy. Their linguistic isolation from neighboring Italian populations and their documented migration history, make such minorities particularly effective for investigating the interplay between cultural, geographic and historical factors. Nevertheless, the extent of Arbereshe genetic relationships with the Balkan homeland and the Italian recipient populations has been only partially investi…
Earthquake-resistant construction techniques in Italy between 1880 and 1910: alternatives to reinforced concrete
2017
The series of earthquakes that struck Italy between the late nineteenth century and the first decade of the twentieth century spurred a lively debate about earthquake-resistant buildings that, through the influence of foreign experience, resulted in specialised literature and competitions that gave rise to a series of interesting patents. Innovative construction solutions for seismic areas were largely developed after the earthquake that struck the cities of Messina and Reggio Calabria in 1908, alongside the parallel advances in reinforced concrete. New earthquake-resistant construction solutions were based on a reassessment of traditional construction methods that used bricks, timber or me…
Carbonate/evaporitic sedimentation during the Messinian salinity crisis in active accretionary wedge basins of the northern Calabria, southern Italy
2020
Abstract This work deals with Messinian deposits belonging to the Neogene infill of the Rossano and Belvedere Basins, respectively developed along the fore-arc and the back-arc areas of the north Calabria accretionary wedge. The main goal is to characterize the carbonate and evaporitic sedimentation during the Messinian Salinity Crisis, in the general framework of the basin architecture and the interplay between eustatic vs tectonic controlled sea-level variations. Fieldwork integrated with seismic lines and well logs interpretations led to the revision of the general stratigraphy of the basins and the proposal of a new sequential stratigraphic model driven by cyclic sea-level variations. E…
Active deformation evidence in the offshore of western Calabria (southern Tyrrhenian Sea) from ultra-resolution multichannel seismic reflection data:…
2020
<p>An ultra-resolution, multichannel seismic reflection data set was collected during an oceanographic cruise organised in the frame of the “<em>Earthquake Potential of Active Faults using offshore Geological and Morphological Indicators</em>” (EPAF) project, which was founded by the Scientific and Technological Cooperation (Scientific Track 2017) between the Italian Ministry of Foreign Affairs and International Cooperation and the Ministry of Science, Technology and Space of the State of Israel. The data acquisition approach was based on innovative technologies for the offshore imaging of stratigraphy and structures alo…
Considerazioni citotassonomiche e corologiche su Allium chamaespathum Boiss. (Alliaceae) geofita nuova per la flora italiana.
2010
Oggetto di questo studio è una singolare popolazione di Allium a fioritura autunnale, rinvenuta presso Reggio Calabria (Italia meridionale), la quale, per alcune caratteristiche vegetative e fiorali, rientra chiaramente nella sezione Allium. Le piante sono caratterizzate da un habitus robusto, foglie subcilindriche ampiamente fistolose, spata unica, caduca, slargata, con appendice fistolosa, lacerantesi lateralmente, infiorescenza globosa, densa, perianzio cilindrico con tepali conniventi, stami con filamenti laminari, dimorfi, gli esterni semplici e gli interni tricuspidati, e ovario con nettari ben sviluppati. Oltre alla fioritura tardiva (IX-X), gli individui di questa popolazione, prese…
DENTRO IL PAESAGGIO. Una casa in Calabria
2021
Progettare un’architettura in Calabria impone una chiave interpretativa. Confrontarsi con i caratteri fisici di un’orografia a tratti impetuosa e dirompente, alternata ad inaspettate ampie dilatazioni degli invasi, delinea due strade: vi si può rimanere schiacciati e per questo provare a superare il proprio complesso adoperandosi con la mimesi o, per opposto, prodigarsi in un dialogo a distanza nel quale la dimensione antropica e i caratteri del sito dispongono le premesse di un vicendevole ascolto. In entrambi i casi, è la forza ancora tellurica degli ultimi resti del paesaggio originario italiano a disporre le premesse di una riflessione.
The Calabrian Stage redefined
2008
The name Calabrian was introduced in the geological literature by the French stratigrapher Maurice Gignoux in 1910, and later described in his important monograph (633 pages) "Les formations marines pliocènes et quaternaires de l'Italie du sud et de la Sicile" published in 1913. Detailed data were provided on several sections (Santa Maria di Catanzaro, Caraffa, Monasterace, Palermo) and on their fossil content. The Calabrian Stage has commonly been used for over fifty years as the oldest subdivision of the Quaternary, notably in the time scales of Berggren & van Couvering (1974) and Haq & Eysinga (1987). However, after the GSSP for the Pliocene/Pleistocene boundary (P/P) was approved by INQ…
Millstones as indicators of relative sea-level changes in northern Sicily and southern Calabria coastlines, Italy
2011
Abstract New data are presented for late Holocene relative sea-level changes in two coastal sites of Sicily and Calabria, southern Italy. Reconstructions are based on precise measurements of submerged archaeological remains that are valuable indicators of past sea-level position. The archaeological remains are millstone quarries carved on sandstone coastal rocks and nowadays partially submerged which, to the authors’ knowledge, are used for the first time as sea-level markers. Millstones of similar typology are located on the coast of Capo d’Orlando (northern Sicily) and Capo dell’Armi (southern Calabria). When the archeologically-based sea-level position is compared with the shoreline elev…
INTEGRATED CALCAREOUS PLANKTON BIOSTRATIGRAPHY OF SELECTED MIOCENE SUCCESSIONS IN THE NORTHERN CALABRIA (ITALY).
2005
An integrated calcareous plankton biostratigraphic approach on six sections cropping out in Northern Calabria allowed to define a revised chronostratigraphic framework for Tortonian-Messinian deposits. Four sections have been investigated in the Amantea Basin (Timpone Napoli, Vallone Salina, Case Vespano, and Cozzo Salice) and two in the Rossano Basin (Vallone Casino and Cozzo Sant'Isidoro). Biostratigraphic analyses have been based on quantitative counting of planktonic foraminifers and semiquantitative counting of nannofossils. The Timpone Napoli and Vallone Salina sections are Late Tortonian in age and referable to the Globorotalia suterae Zone. In terms of nannofossils zonal scheme thes…
