Processes occurring in magma storage regions control magma compositions and properties, which in turn affect ascent dynamics, eruptive behaviour, and emplacement mechanisms of volcanic products thus representing a paramount factor for the environmental and societal impact of volcanic eruptions.
Magma fractionation, degassing, mixing, and country-rock assimilation occur on a wide range of timescales and depths. Decompression and cooling driven by the ascent of magmas in volcanic conduits also impart their signature on eruptive products, complicating the interpretation of physico-chemical changes of the system. Indeed, during magma ascent, several physical and chemical processes are taking place, which can affect eruptive behavior and the style of activity.
Textural, chemical, and isotopic characteristics of eruptive products can be used as forensic tools to elucidate the inner workings of magmatic plumbing systems as well as pre- and syn-eruptive processes. Similarly, analytical/field observations, laboratory experiment and numerical modelling can also provide a useful tool to investigate pre- and syn-eruptive processes. Together, these information are of paramount importance for policymakers in charge of mitigating the risks associated with volcanic eruptions.
In this session we welcome a wide range of petrological, geochemical, geophysical and volcanological studies, based on natural, experimental, theoretical, or numerical-based approaches, with the scope of shedding light on magmatic processes occurring at depth and during ascent towards the surface. We also encourage submissions of contributions that deal with the mitigation of the hazards associated with volcanic activity. Interdisciplinary work considering the close and complex interplay between magmatic processes, conduit dynamics, eruptive behaviour, and emplacement mechanisms are of particular interest.
