    Structural features of Panarea volcano in the frame of the Aeolian Arc (Italy): Implications for the 2002–2003 unrest (2009)
    Elsevier Ltd
    Details
    Publication Date: 2017-04-04
    Description: Panarea, characterized by gas unrest in 2002–2003, is the volcanic island with the least constrained structure in the eastern-central Aeolian Arc (Italy). Based on structural measurements, we define here its deformation pattern relative to the Arc. The main deformations are subvertical extension fractures (63% of data), normal faults (25%) and dikes (12%). The mean orientation of the extension fractures and faults is ∼N38◦E, with a mean opening direction of N135◦ ±8◦, implying extension with a moderate component of dextral shear. These data, matched with those available for Stromboli volcano (pure opening) and Vulcano, Lipari and Salina volcanoes (predominant dextralmotions) along the eastern-central Arc, suggest a progressivewestward rotation of the extension direction and an increase in the dextral shear. The dextral shear turns into compression in the western arc. The recent unrest at Panarea, coeval to that of nearby Stromboli, may also be explained by the structural context, as both volcanoes lie along the portion of the Arc subject to extension.

    Gas hazard assessment at the Monticchio Mt. Vulture, a volcano in Southern Italy (2009)
    Wiley-Blackwell
    Details
    Publication Date: 2017-04-04
    Description: Geochemical investigations have shown that there is a considerable inflow of gas into both crater lakes of Monticchio, Southern Italy. These lakes are located in two maars that formed 140 000 years ago during Mt. Vulture volcano s last eruptive activity. Isotopic analyses suggest that CO2 and helium are of magmatic origin; the latter displays 3He ⁄ 4He isotope ratios similar to those measured in olivines of the maar ejecta. In spite of the fact that the amount of dissolved gases in the water is less than that found in Lake Nyos (Cameroon), both the results obtained and the historical reports studied indicate that these crater lakes could be highly hazardous sites, even though they are located in a region currently considered inactive. This could be of special significance in very popular tourist areas such as the Monticchio lakes, which are visited by about 30 000 people throughout the summer, for the most part on Sundays.

    L’impatto dell’evento combinato Ignimbrite Campana-Heinrich Event 4 sugli ecosistemi umani europei di 40 ka BP (2007)
    CNR Edizioni
    Details
    Publication Date: 2017-04-03
    Description: Vengono presentati i risultati di uno studio interdisciplinare sull’impatto dell’evento combinato vulcanico-climatico della “super-eruzione” dell’Ignimbrite Campana (IC) avvenuta ai Campi Flegrei e dell’episodio di acuto raffreddamento dell’Heinrich Event 4 (HE4), entrambi di c. 40.000 anni BP, sugli ecosistemi umani europei al passaggio Paleolitico medio/Paleolitico superiore. Questi risultati indicano che il raffreddamento globale indotto dall’evento eruttivo dell’IC, stimato intorno ai 3-4 °C, si determinò esattamente all’inizio dell’HE4, con probabile prolungamento ed amplificazione degli effetti climaticoambientali e conseguente notevole impatto sui gruppi paleolitici. Questa ipotesi è argomentata sulla base delle tendenze e dei processi climatici in prossimità dell’evento dell’IC, sui parametri fisici e chimici dell’eruzione nonché sulle evidenze archeologiche derivanti dall’analisi sia del contesto generale europeo che di alcune importanti sequenze stratigrafico-culturali contenenti il tefra dell’IC distribuite in un’ampia area tra l’Italia meridionale e la Russia.
