    Description: In this paper, we describe the 1809 eruption of Mt. Etna, Italy, which represents one historical rare case in which it is possible to observe details of the internal structure of the feeder system. This is possible thanks to the presence of two large pit craters located in the middle of the eruptive fracture field that allow studying a section of the shallow feeder system. Along the walls of one of these craters, we analysed well-exposed cross sections of the uppermost 15–20 m of the feeder system and related volcanic products. Here, we describe the structure, morphology and lithology of this portion of the 1809 feeder system, including the host rock which conditioned the propagation of the dyke, and compare the results with other recent eruptions. Finally, we propose the dynamic model of the magma behaviour inside a laterally-propagating feeder dyke, demonstrating how this dynamic triggered important changes in the eruptive style (from effusive/Strombolian to phreatomagmatic) during the same eruption. Our results are also useful for hazard assessment related to the development of flank eruptions, potentially the most hazardous type of eruption from basaltic volcanoes in densely urbanized areas, such as Mt. Etna.

    Convivere con i rischi naturali (2015)
    Società editrice Il Mulino, Bologna

    Publication Date: 2017-04-04
    Description: I fenomeni naturali, anche nei loro aspetti più temibili, ci ricordano che la Terra è un pianeta vivo. L’Italia, paese geologicamente fragile, è soggetto a terremoti, eruzioni, frane, inondazioni dagli effetti spesso devastanti. A un ambiente fisico così difficile si sono colpevolmente aggiunte l’incuria e la disattenzione dell’uomo. Quali sono le cause dei fenomeni naturali? In che misura sono prevedibili? Come possiamo difenderci? Il primo passo è trasformare la cultura del soccorso e dell’emergenza in cultura della prevenzione e della mitigazione del rischio.
