Production of magma and assembly of volcanic plumbing systems* *Session: Illuminating Active Volcanic Plumbing Systems* In the past decades, geophysical studies have revealed volcanoes to be complex systems in which chemical and physical processes are inextricably linked to one another. Gaining a detailed understanding of the distribution and composition of magmas in storage can increase our understanding of that volcanic systemâ??s growth and evolution. Constraints from multiple techniques including seismic, geodesy, potential field, and electromagnetic methods have the ability to inform about processes and illuminate deep within a volcanic plumbing system. These methods provide key constraints that cannot be obtained in other ways. Joint inversion or joint interpretation of distinct geophysical datasets is a particularly powerful tool as it often reveals complementary aspects of the same volcanic system. Additionally, integration of petrologic constraints into the interpretation of geophysical studies broadens understanding of that volcanic system. In this session, we welcome studies that use various methods to illuminate the structure and plumbing of active volcano systems. *Abstract submissions due Dec 20th* *https://on-line-form.eu/iavcei2025sa/abstracts/ <https://urldefense.com/v3/__https://on-line-form.eu/iavcei2025sa/abstracts/__;!!IKRxdwAv5BmarQ!aS-N5Uj_pdt6sNshpO1pQHahfbeJv67lWrianJjAdfUzxAzsn9Ey2bJHzoOyVVEe9eSnah83FjrAD5KtT7fcwM7tFg$>* *CONVENERS* *Roger Denlinger* (US Geological Survey, Vancouver, Washington, United States) *Freysteinn Sigmundsson* (University of Iceland, Reykjavik, Iceland) *Brandon Schmandt* (University of New Mexico, Albuquerque, New Mexico, United States) *Ninfa Bennington* (US Geological Survey, Hilo, Hawaii, United States) *Alex Iezzi* (US Geological Survey, Vancouver, Washington, United States) 6-6-6-6-6-6-6-6-6-6-6-6-6 ------------------------------
