    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 ...

    Influence of climate change on magmatic processes: What does geodesy and modeling of geodetic data tell us? 
    Sigmundsson, Freysteinn; Parks, Michelle; Geirsson, Halldór; Albino, Fabien; Schmidt, Peter; Li, Siqi; Pálsson, Finnur; Ófeigsson, Benedikt G.; Drouin, Vincent; Aðalgeirsdóttir, Guðfinna; Magnússon, Eyjólfur; Hooper, Andy; Hreinsdóttir, Sigrún; Maclennan, John; Sturkell, Erik; Trasatti, Elisa (Elsevier, 2024)
    Anthropogenic global climate change is causing ice mass loss in all glacierized regions in the world. Iceland provides conditions that make it an efficient laboratory to study the effects of retreating glaciers on magmatic activity, as retreating ...

    A Preseismic Strain Anomaly Detected Before M6 Earthquakes in the South Iceland Seismic Zone From GPS Station Velocities 
    Arnadottir, Thora; Haines, John; Geirsson, Halldor; Hreinsdóttir, Sigrún (American Geophysical Union (AGU), 2018-12)
    The South Iceland Seismic Zone (SISZ) accommodates E‐W translation due to oblique spreading between the North American and the Eurasian plates in South Iceland with ruptures on N‐S faults. Strain is released in earthquake sequences that last days to ...
