\"MAXI-Plume\" in a nutshell<\/h2>\n

MAXI-Plume stands for \"Ma<\/strong>ss flux<\/strong> i<\/strong>nvestigations on ash plume<\/strong>s\" and is the acronym for a 3-years research project carried out at the Institute of Earth Sciences at University of Iceland since 01. 06.2020. MAXI-Plume is supported by an Icelandic Research Fund (IRF) postdoc grant by The Icelandic Centre for Research (RANN\u00cdS<\/a>).<\/p>\n

MAXI-Plume is focused on ash injection by volcanic plumes generated during explosive eruptions in Iceland. By integrating monitoring, geological field studies, models and experiments, MAXI-Plume addresses still open questions crucial for understanding plume dynamics: the link between magma fragmentation in the conduit and resulting source conditions, and wind entrainment. Both factors control the evolution of a plume.<\/p>\n

In particular, MAXI-Plume focusses on the mass flux at the vent, i.e. the mass of tephra and volcanic gases released per time. Within MAXI-Plume the mass flux of the most recent explosive Icelandic eruptions (e.g., Eyjafjallaj\u00f6kull 2010, Gr\u00edmsv\u00f6tn 2004\/11) is quantified by merging results of measurements on ash deposits with newly developed techniques using video analysis. The values obtained serve as a data base for comparing and fine-tuning existing plume models, in particular by adjusting the parameter describing wind entrainment. Complementary experiments help to investigate the dependencies of plume dynamics on wind entrainment processes.<\/p>\n

The ultimate goal of MAXI-Plume is to enhance real-time mass flux assessment in future eruption scenarios.<\/p>\n
