3-3-3-3-3-3-3-3-3-3-3-3-3 From: "Andrews, Benjamin" <AndrewsB@xxxxxx> Dear Colleagues, We would like to draw your attention to AGU Fall Meeting Session V015: Explosive eruption processes (confex.com) <https://urldefense.com/v3/__https://agu.confex.com/agu/fm23/prelim.cgi/Session/191365__;!!IKRxdwAv5BmarQ!f3a_frQJV7pSUb7ls4FPUaKJyOjsUSkgRxSY-ymJriouIrnl1AWq82LKSPYOrc3jOhJCbHA61E5jr6UsYmwN$> Explosive volcanic eruptions encompass processes that span an enormous range of physical scales. Magma fragmentation occurs over microns to 10s of centimeters during millisecond timescales. Eruption jets and plumes turbulently mix with the atmosphere over 100s of meters and 10s of seconds. Pyroclastic current transport and sedimentation can be controlled by either (or both) granular flow mechanics or turbulent flow processes. All these processes are challenging to observe because of volcanic hazards and their locations within the conduit or opaque eruption clouds. Understanding explosive eruption processes helps to interpret changes in eruption style recorded by deposits, and will hopefully lead to better forecasting of future activity. We seek submissions that study explosive eruption processes through direct observations, fieldwork examining ancient deposits, pyroclast textural analysis, laboratory experiments, and/or numerical simulations. We hope to elicit a discussion of eruption dynamics that includes eruption case studies and broader descriptions of explosive processes. As a reminder, the abstract submission deadline is 2 August.
