    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 ...

    Reinterpretation of the RRISP-77 Iceland shear-wave profiles 
    Menke, William; Brandsdóttir, Bryndís; Einarsson, Páll; Bjarnason, Ingi Þorleifur (Oxford University Press (OUP), 1996-07)
    Two shear-wave profiles, E and G, collected during the 1977 Reykjanes Ridge Iceland Seismic Experiment have played an important role in models of the Icelandic crust. They were originally interpreted as indicating very low shear-wave velocities and ...

    Seismicity on Conjugate Faults in Ölfus, South Iceland: Case Study of the 1998 Hjalli‐Ölfus Earthquake 
    Mozhikunnath Parameswaran, Revathy; Þorbjarnardóttir, Bergþóra Sólveig; Stefánsson, Ragnar; Bjarnason, Ingi Þorleifur (American Geophysical Union (AGU), 2020-08)
    The Ölfus seismic belt lies at the western end of the ~E‐W sinistral transform shear zone in South Iceland, called the South Iceland Seismic Zone (SISZ), where most seismicity and surface faulting show ~N‐S dextral slip. Unlike the rest of SISZ, ...
