Dear colleagues, We are excited to host a session on mush destabilisation in the lead-up to volcanic eruptions at the upcoming IAVCEI Scientific Assembly from 30th January to 3rd February 2023 in Rotorua, New Zealand! Please consider submitting an abstract by 2nd September 2022! https://confer.eventsair.com/iavcei2023/call-for-abstracts *Unlocking the mush: Integrated approaches to track the lead-up to volcanism* *Growing evidence suggests that mush systems can build up over protracted periods and yet catastrophically switch to a state of unrest and eruption on near-instantaneous timescales, posing a major challenge for volcano monitoring efforts. Understanding the birth, growth and potential mobilisation of mush systems is hence of major interest in volcanology, and requires a comprehensive approach to the study of magma transport, storage and differentiation through the crust. Crucially, the rates, depths and complexities inherent to magmatic plumbing systems have a major impact on the behaviour, duration and intensity of ensuing volcanic eruptions. * *We invite a wide range of contributions including field, petrographic, geochemical, experimental, numerical and/or geophysical approaches to constrain the spatio-temporal evolution of mush systems and the key processes that lead to eruption. We encourage combinations of conventional methodologies with innovative techniques to interrogate petrological and geochemical records and their links to monitoring data. * *Keynote speaker: Prof Jon Blundy (University of Oxford, UK) * *IAVCEI 2023 Theme: Eruption triggers and styles: From precursors to eruption* https://confer.eventsair.com/iavcei2023/scientific-symposia Thank you very much for considering our session, we are looking forward to seeing you in New Zealand!
