Academic literature on the topic 'NE Friuli'

We reconstructed the seismotectonic setting of the area comprising the northeastern Friuli Plain and the Julian pre-Alpine border (NE Italy) by integrating geological and seismological data. The study area represents the junction between the SSE-verging polyphase thrust-front of the south-Alpine Chain and the NW–SE-trending strike-slip faults of the eastern Friuli–western Slovenia domain. Following a multidisciplinary approach, the 3D geometry of the Susans–Tricesimo thrust system was reconstructed through the elaboration of four geological cross sections derived from the interpretation of ENI industrial seismic lines. In a second step, the seismogenic volume of the central-eastern Friuli area was investigated through hypocentral distribution analysis: the seismic events of the latest 50 years (1976–1977 and 1978–2019 time intervals) were plotted on four NE-SW-oriented seriated sections together with the fault plane’s geometry. Through this procedure, we were able to investigate the relationship between the NW-SE-striking high-angle faults, which characterize the northern Julian pre-Alps, and the WSW-verging medium-angle reverse fronts located at the piedmont of the Friuli plain, which experienced NW-SE- to NNW-SSE-oriented compression starting at least from the Pliocene. In detail, we examined the involvement of these structures during the seismic sequences of May and September 1976, in terms of activation and/or interaction. The resulting seismotectonic model highlights the interplay between transpressive/strike-slip and reverse planes. In particular, this study suggests that Predjama and Maniaglia transpressive faults strongly control the stress release and likely played a fundamental role both during the 6 May (Mw 6.5) and 15 September (Mw 6.0) Friuli earthquakes.

In aree plurilingui, l’esposizione di indicazioni toponimiche in lingue diverse costituisce un contributo fondamentale per garantire la visibilità delle lingue del territorio. Nel caso di comunità linguistiche minoritarie con spiccata frammentazione dialettale, con una varietà di riferimento di recente codificazione o prive di essa, nonché in zone con scarso orientamento verso una norma esogena (isole linguistiche, ma talora anche territori di confine), la decisione di esporre toponimi in più lingue non è tuttavia scevra di problemi: va prediletta la forma locale, spesso di diffusione limitata, o una forma sovralocale? Nel caso di lingue non codificate, a quale tradizione grafica ci si deve orientare? All’esempio del Friuli Venezia Giulia, nel nordest d’Italia, illustreremo come le scelte toponimiche, talora contrastanti a seconda degli attori che le attuano, possano suscitare irritazioni e reazioni negative nella popolazione. Cercheremo poi di indagare i motivi che guidano tali scelte e quale cultura della memoria ne emerga.

Abstract. The article deals with public participation in recovery after earthquakes in the border region of Friuli (NE Italy) and the Upper Soča Valley (NW Slovenia) in 1976 (magnitude 6.4, 6 May; magnitude 6.1, 15 September), 1998 (magnitude 6.0, 12 April), and 2004 (magnitude 4.9, 7 July). It highlights the differences in the concepts of the post-earthquake recovery, taking into consideration the different political systems between the two countries (capitalist Italy vs. communist Slovenia in 1976) and changes in recovery after the change of political system in Slovenia (communist Slovenia in 1976 vs. capitalist Slovenia in 1998 and 2004).

Three old specimens of <em>Stephanopachys</em> <em>linearis</em> (Kugelann, 1792) from NE Italy, Udine Province (Friuli-Venezia Giulia Region) are recorded. This is the first certain record of this species for Italy since the only previous records, from South Tyrol, were doubtful. This new record is of high conservation value, since this species is protected by the Habitats Directive in the European Union. Distributional and biological data on <em>S. linearis</em> are summarized and it is documented that the previous, doubtful literature records from South Tyrol are erroneous.

Les sociétés européennes perçoivent la période actuelle comme marquée par la recrudescence des crues ou des inondations ayant des conséquences catastrophiques. Aboutir à une meilleure définition des risques naturels est ainsi devenu un des enjeux majeurs pour la recherche et pour ses applications pratiques en terme d'aménagement du territoire. Dans l'arrière pays montagneux du pourtour méditerranéen, la tâche est d'autant plus ardue que les phénomènes torrentiels sont fréquents, de grande ampleur, multiples et en interaction permanente (crues associées ou non à des inondations, mouvements de terrain) et que les effets d'échelle vis-à-vis des transferts sédimentaires restent encore mal compris. Ce mémoire analyse l'évolution du risque torrentiel d'un bassin versant des Préalpes Carniques orientales (le bassin versant de la rivière Arzino, Frioul) en examinant le risque dans toutes ses dimensions - de l'aléa à la vulnérabilité en passant par la perception des sociétés - sur une période suffisamment longue et documentée : le XXe siècle. Les habitants de la vallée y perçoivent une augmentation de l'aléa : l'objectif est de comprendre pourquoi et si cette perception est justifiée. À l'aide d'une approche pluriscalaire et pluridisciplinaire associant des techniques variées (levées hydrogéomorphologiques, statistiques, photo-interprétation, S. I. G. Et techniques d'enquêtes), ce travail a montré qu'au cours du XXe siècle le système torrentiel est resté en équilibre dynamique, d'où une permanence spatiale de l'aléa. Pourtant, le risque s'est déplacé pour se concentrer dans les fonds de vallée, au sein et autour des villages, le long des routes et, en particulier, à l'aval du bassin versant de l'Arzino. Ce changement reflète surtout l'évolution de la vulnérabilité, d'autant plus accrue que les habitants n'acceptent plus le risque. En montrant la nécessité de prendre en compte toutes les dimensions du risque torrentiel, ce travail invite enfin à repenser sa gestion par une approche intégrée et multirisques
European societies generally consider the last twenty years as a period of increased catastrophic hazards and floods. A better assessment of the nature and modalities of torrential hazards has thus became a major topic of research and management. In the mountainous hinterland of the Mediterranean Sea, such a task turns out to be quite uneasy owing to the high frequency of large scale torrential events, that are various in nature and in constant interaction (high flows associated or not to floods and landslides). Moreover, sediment supply processes at various scale still remains poorly known. This work deals with the evolution of torrential hazards and risks in the Arzino catchment, in the Carnic Pre-Alps (Friuli). The starting point of our research is the feeling of the inhabitants of this valley who perceive an increase of torrential hazards since the end of the last World War. We aim at understanding why and to what extent their statement is justified. We adopted a multiple approach study - that considers hazard, vulnerability and perception by societies -by using the historical (archives) documentation available during the 20th century. We also adopted a multi-disciplinary and multi-scale analysis that combined various techniques (hydrogeomorphological measures, statistics, interpretation of air-photographs, G. I. S. And techniques of public survey). In contrast to the inhabitant perception, we were able to show the permanence of a dynamical equilibrium in the torrential System during the twentieth century. Although hazards remained the same, we show that risk increased and the zones at risk are now in the downstream part of the catchment: in and around the villages and nearby the roads, particularly along the river floodplains. This change is a result of increased vulnerability that can be explained by a low resilience of the inhabitants, who do not anymore accept the risk. Finally, this work not only demonstrates the necessity of taking ail risk's aspects into account for: it also suggests that from now on, risk management should be reconsidered with an integrated and multi-risks approach
