They can become big and are heavy, and the material on which they are built, and by which they are built, can be weak. This combination promotes anomalous movement or even catastrophic collapses of parts of the volcano with severe consequences. Just like an iceberg, only a small portion of the whole volcanic edifice sticks out if the water. Yet, nearly all of our monitoring and surveillance efforts concentrate on the small subaerial part. In the <a href=\"https:\/\/www.pre-collapse.eu\/research-background\" data-type=\"link\" data-id=\"https:\/\/www.pre-collapse.eu\/research-background\">PRE-COLLAPSE<\/a> group we study how our understanding of the mechanics of the volcano changes when we consider the whole edifice, from its feet in the deep ocean to its top high above sea level. In this talk I want to introduce the main questions, the different perspectives and range of methodologies we use to improve the assessment of the hazards posed by unstable marine volcanoes.<\/p>\n\n\n\n<figure class=\"block-image size-large\"><div class=\"loading-placeholder shine\" style=\"aspect-ratio: 1\/ 0.66796875\"><img decoding=\"async\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" data-src=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1024x684.jpg\" data-srcset=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1024x684.jpg 1024w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-300x200.jpg 300w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-768x513.jpg 768w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1536x1025.jpg 1536w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-2048x1367.jpg 2048w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-210x140.jpg 210w\" width=\"1024\" height=\"684\" src=\"\/\/:0\" class=\"lazyload\" alt=\"2023 08 22 Krakatau Morelia Urlaub C Jonas Preine Uni Hamburg04\" style=\"\"   loading=\"lazy\" \/><noscript><img decoding=\"async\" width=\"1024\" height=\"684\" src=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1024x684.jpg\" class=\"lazyload\" alt=\"2023 08 22 Krakatau Morelia Urlaub C Jonas Preine Uni Hamburg04\" style=\"\" srcset=\"https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1024x684.jpg 1024w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-300x200.jpg 300w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-768x513.jpg 768w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-1536x1025.jpg 1536w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-2048x1367.jpg 2048w, https:\/\/submarine.iavceivolcano.org\/content\/uploads\/sites\/6\/2023\/11\/2023-08-22_krakatau_morelia_urlaub_c_jonas-preine_uni-hamburg04-210x140.jpg 210w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" loading=\"lazy\" \/><\/noscript><\/div><figcaption class=\"wp-element-caption\"><em>View of the west flank of Anak Krakatau, which slid down in 2018 and has already formed a new volcanic cone.
