They enable the empirical characterization of volcanic phenomena and provide essential benchmarks for developing analog, numerical, and theoretical models. These models help unravel the underlying physical mechanisms and are crucial for generating predictions to mitigate associated impacts. However, volcanic processes are intrinsically unpredictable, highly variable, potentially threatening to human health and field instruments, and often happen in remote and hazardous environments, inhibiting field investigations. This session seeks studies presenting *in situ *analysis of volcanic processes obtained through classical field measurements and novel techniques including instrumentation and communications in remote settings (autonomous monitoring). We also invite contributions involving various types of models and instruments, from ground-based sampling to drone-embedded devices, which facilitate the study of volcanic processes. *Abstract submissions due 20 December 2024:* *https://on-line-form.eu/iavcei2025sa/abstracts/index.php?coo=1 <https://urldefense.com/v3/__https://on-line-form.eu/iavcei2025sa/abstracts/index.php?coo=1__;!!IKRxdwAv5BmarQ!dcYeD4WCdrikLOck-aCOLmLHGS-eVKlrxeItpYdzGNZZeGW5hqXSCV8CKJxSv9Nbd4aIgbfWlK72bNsRyTTx1HSPgg$>* Conveners: Allan Fries (Université de Genève, Geneva, Switzerland) Simon Thivet (Université de Genève, Geneva, Switzerland) Kristi Wallace (USGS, Anchorage, United States) Emanuela De Beni (INGV Osservatorio Etneo, Catania, Italy) Valentin Fréret-Lorgeril (Laboratoire Magmas et Volcans, Université Clermont Auvergne, Clermont-Ferrand, France) 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
