2-2-2-2-2-2-2-2-2-2-2-2-2 From: Domenico Doronzo <domenico.doronzo@xxxxxxx> Dear All, We wish to draw your attention to the scientific session *S07 - Large eruptions magma-chambers formation and evolution: implications on magmatic processes, eruption dynamics and environmental impact*, which will be held at the 5th edition of the A. Rittmann Conference in Catania, Italy, from September 29 to October 1, 2022. *Information about submitting an abstract to this session (deadline 11 June 2022) **can be found on the conference website* ( https://urldefense.com/v3/__https://www.conferenzarittmann.it/__;!!IKRxdwAv5BmarQ!Zr97ZsQy8e-WWqpXzlaMnaE1knrwTdPrPBtJrgEQMoSDZyqXaUFxymb8qsDdGhwQ6ljmPlC_yIEmV5i-$ <https://urldefense.com/v3/__https://www.conferenzarittmann.it/__;!!IKRxdwAv5BmarQ!aoW1MUU1p1z5BR00FDWhz_Ri_1h7-ox1YMFdSM-B0589av83MW4yfp6syXgEtRBSz8QxTFMRxGRM6e7CKu4C_nuByo8$> ). Sandro de Vita, Claudia D'Oriano, Ilenia Arienzo, Domenico Doronzo Session details Reconstructing the structure, timing and modalities of growth and evolution of the magmatic feeding system/s associated with high-magnitude eruptions is one of the most challenging targets that the volcanological community is facing nowadays. These issues are of primary importance for understanding the evolution of volcanism in active volcanic areas, as magma accumulation represents a pre-requisite for the growing of large magma reservoirs and then for the occurrence of high-magnitude eruptions. This translates into specific eruption mechanisms and phenomena such as: structure-controlled eruptions, Plinian and ultra-Plinian eruptions, caldera collapse, pyroclastic density currents and ash fallout generation and dispersal, and caldera resurgence. Moreover, high-magnitude eruptions can have a dramatic impact on the environment and human settlements and life, in terms of direct geomorphological modifications and climate changes. Aim of this session is to bring together the most recent studies focused on volcanic stratigraphy, tephra correlation, eruption dynamics, geochemical characterization of the eruptive products, magma withdrawal, timescales of magma chamber (storage, mixing/mingling and refilling), and conduit (ascent) processes. We encourage the submission of interdisciplinary contributes on geological, tephrostratigraphical, sedimentological, volcanological, structural, petrological, geochronological and geophysical investigations, as well as numerical modelling of large eruptions, ash dispersion in the atmosphere and climatic impact assessment. 2-2-2-2-2-2-2-2-2-2-2-2-2 ------------------------------
