Dear colleagues,
We kindly invite you to submit a contribution to the Session S1.2 "Exploring Volcanic Climactic Explosive Activity From Magma Source to Ground and Atmosphere", which will be carried out at the Cities on Volcanoes 10 Meeting, to be held in Naples-Italy, between September 2 and 7 of 2018.
The session is organized by Patrick Allard, Alessandro Bonaccorso, Sonia Calvari, and Andrew Harris.
Climactic or paroxysmal explosive activity from active volcanoes is one of the most spectacular natural phenomenon, causing sustained eruptive columns and ash plumes spreading for tens of km in height and whose fallouts involve extremely large areas. These events are recognised as having a strong impact not only at a local scale but also on far areas and, indeed, can significantly affect the atmosphere, and the environment in the overall. The most devastating and recent example occurred in 2010, when the Icelandic Eyiafjallajökull volcano erupted disrupting air traffic all over Europe for weeks. Between 2008 and 2013, the long-lasting eruption of Chaitén volcano in Chile produced plumes 14-20 km high reaching the coast of Argentina and causing ash fallout as far as 800 km from the vent, and the continuously erupting volcanoes of the Kamchatka Peninsula and of the Aleutian arc have caused often treats to air traffic. The eruption of Pinatubo in 1991 (Philippines) had a strong impact all over the globe, causing significant and measurable atmospheric perturbation and impacting the world temperature. More recently, Mount Etna in Italy displayed tens of paroxysmal explosive episodes in 2011-2013, and also sequences of several episodes in just a few days in 2015 and 2016, affecting air traffic, viability, settlements, environment, and economics. Over time, several studies have been devoted to understanding what drives the huge size of these explosive events, involving several eruptive styles. These span from weak lava fountains, to phreatomagmatic eruptions, to powerful Vulcanian and Plinian eruption styles. Owning to the intrinsic threating characteristics, so far great efforts have been made trying to detect precursory signals, parameterise the phenomena, apply conceptual and experimental models, and assess the associated hazards. We encourage contributions to review the key aspects of climactic or paroxysmal eruptions comprising several eruptive styles and magma compositions, as well as new findings relating to source characterisation, application of novel/integrated monitoring techniques enabling the retrieval of new parameters and step forwards in the knowledge of climactic or paroxysmal activity all over the world, technology improvements allowing higher quality of observations, data integration and modelling, and providing more precise hazard assessment tools. Integrated multidisciplinary presentations on single eruptive episodes, as well as single techniques applied to different eruptive episodes and/or volcanoes and multidisciplinary contributions are especially welcome.
Looking forward to meet you there!
Patrick, Alessandro, Sonia & Andrew
