6-6-6-6-6-6-6-6-6-6-6-6-6 From: "Andrews, Benjamin" <AndrewsB@xxxxxx> Dear colleagues, On behalf of my fellow conveners, I would like to draw your attention to Fall AGU Session V032 What Goes Up Must (Eventually) Come Down: Dynamics of and Deposition from Volcanic Eruption Columns, Plumes, and Pyroclastic Density Currents (confex.com) <https://urldefense.com/v3/__https://agu.confex.com/agu/agu24/prelim.cgi/Session/228435__;!!IKRxdwAv5BmarQ!eJnxAZixAfQgVRmWx9cOBwLjhK_ZNuJd1ZUZpZAq9q3Ag6ThO3YABS1w3auDRLu5WQmnDtYGSiDXjh_1kLMH9ftr2g$> â??Volcanic eruption columns, plumes, and pyroclastic density currents (PDCs) can rapidly distribute ash and other pyroclastic material into the atmosphere and over local and distal areas. Dispersal of this material can strongly impact and alter the landscape; those processes can also present substantial hazards to human life and property. Understanding explosive eruption dynamics is thus critical to interpreting ancient deposits and forecasting modern or future volcanic activity. This session will explore physical eruption processes using fieldwork on ancient or modern eruptions, observations of modern eruptions, computational modeling, analog experiments, or some combination thereof. Particular areas of interest include (1) the effects of vent overpressure and vent geometry on eruption processes, (2) air entrainment into eruption columns and PDCs, (3) controls on eruption column height, (4) particle aggregation, charging, and volcano lightning, (5) plume dispersal and sedimentation, (6) PDC transport and deposition, and (7) buoyancy reversal and plume formation from PDCs.â?? As a reminder, abstract submission closes at 23:59 p.m. ET/03:59 +1 GMT If you have any questions about the session, feel free to email me. Sincerely, Ben Benjamin Andrews Corrado Cimarelli Kristen Fauria 6-6-6-6-6-6-6-6-6-6-6-6-6 ------------------------------
