I&#8217;ll discuss aspects of magma energy budget, external water entrainment and mixing, and fragmentation and fine ash production, adding context with a few key observations from real eruptions. To explore these concepts a little further, I&#8217;ll close with a thought experiment on the energy balance and driving mechanisms of the 2022 Hunga-Tonga Hunga-Ha&#8217;apai eruption column.<\/p>\n\n\n\n<figure class=\"block-image size-large\"><div class=\"loading-placeholder shine\" style=\"aspect-ratio: 1\/ 0.6962890625\"><img decoding=\"async\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" data-src=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1024x713.jpg\" data-srcset=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1024x713.jpg 1024w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-300x209.jpg 300w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-768x535.jpg 768w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1536x1070.jpg 1536w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-2048x1427.jpg 2048w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-201x140.jpg 201w\" width=\"1024\" height=\"713\" src=\"\/\/:0\" class=\"lazyload\" alt=\"Plumeschematic Double\" style=\"\"   loading=\"lazy\" \/><noscript><img decoding=\"async\" width=\"1024\" height=\"713\" src=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1024x713.jpg\" class=\"lazyload\" alt=\"Plumeschematic Double\" style=\"\" srcset=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1024x713.jpg 1024w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-300x209.jpg 300w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-768x535.jpg 768w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-1536x1070.jpg 1536w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-2048x1427.jpg 2048w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/08\/plumeschematic_double-201x140.jpg 201w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" loading=\"lazy\" \/><\/noscript><\/div><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>On September 6th, 2023, 16:00 UTC, CoSV hosted the webinar entitled &#8220;Shallow subaqueous and subglacial explosive eruptions: Comparing models and case studies to explore controls on column rise and stratospheric injection\u201d.
