    A dynamic mid-crustal magma domain revealed by the 2023 to 2024 Sundhnúksgígar eruptions in Iceland 
    Matthews, Simon W.; Caracciolo, Alberto; Bali, Enikő; Halldórsson, Sæmundur A.; Sigmarsson, Olgeir; Guðfinnsson, Guðmundur H.; Pedersen, Gro B. M.; Robin, Jóhann Gunnarsson; Marshall, Edward W.; Aden, Araksan A.; Gísladóttir, Bryndís Ýr; Bosq, Chantal; Auclair, Delphine; Merrill, Heini; Levillayer, Nicolas; Löw, Noëmi; Rúnarsdóttir, Rebekka Hlín; Johnson, Sóley M.; Steinþórsson, Sveinbjörn; Drouin, Vincent (American Association for the Advancement of Science (AAAS), 2024-10-17)
    Mid-crustal magma domains are the source of many basaltic eruptions. Lavas from individual eruptions are often chemically homogeneous, suggesting they derive from single well-mixed magma reservoirs. The 2023-2024 eruptions at Sundhnúksgígar in the ...

    Fracturing and tectonic stress drive ultrarapid magma flow into dikes 
    Sigmundsson, Freysteinn; Parks, Michelle; Geirsson, Halldór; Hooper, Andrew; Drouin, Vincent; Vogfjörd, Kristín S.; Ófeigsson, Benedikt G.; Greiner, Sonja H. M.; Yang, Yilin; Lanzi, Chiara; De Pascale, Gregory P.; Jónsdóttir, Kristín; Hreinsdóttir, Sigrún; Tolpekin, Valentyn; Friðriksdóttir, Hildur María; Einarsson, Páll; Barsotti, Sara (American Association for the Advancement of Science (AAAS), 2024-03-15)
    Many examples of exposed giant dike swarms can be found where lateral magma flow exceeded hundreds of kilometers. We show that massive magma flow into dikes can be established with only modest overpressure in a magma body, if a large enough pathway ...

    Large volcanic eruptions on Earth commonly occur with a collapse of the roof of a crustal magma reservoir, forming a caldera. Only a few such collapses occur per century, and the lack of detailed observations has obscured insight into the mechanical ...
