Dear colleagues, we would like to draw your attention to session *GMPV8.4*: "*Understanding magmatic processes: from magma storage to eruptive behaviour, and implications for volcanic hazard*" Convener: Fabio Arzilli (UNICAM) Co-conveners: Eleonora Braschi (CNR-IGG), Giuseppe La Spina (INGV), Emily Bamber (CNR-ISSMC), Chiara Maria Petrone (NHM-London) which will take place at the next EGU’s General Assembly in Vienna (Austria) from *27 April to 02 May 2025*. In this session we welcome a broad range of contributions from researchers investigating the processes occurring in magmatic storage to conduit regions, including petrological, geochemical, and volcanological studies. We welcome natural, experimental, theoretical, numerical-based and multidisciplinary approaches. The aim is to promote discussion on the integration of data and techniques that best address the connection between magma dynamics at depth and eruptive and emplacement dynamics at the surface, potentially providing new tools to be implemented in petrological monitoring practices. We particularly encourage contributions from early-career scientists and studies that adopt multidisciplinary and/or innovative approaches. Please find further information at: https://meetingorganizer.copernicus.org/EGU25/session/54228 <https://meetingorganizer.copernicus.org/EGU25/sessionprogramme/5521> The *abstract submission deadline is the 15th of January 2025, 13:00 CET.* Guidelines for abstract submission can be found at https://www.egu25.eu/programme/how_to_submit.html If you are an ECR or a researcher from low- to upper-middle income country, you can apply for Travel Support sending the abstract by 2 December 2024, 13:00 CET. More information can be found at the following link: https://www.egu25.eu/guidelines/supports_and_waivers.html Looking forward to your contributions.
