    Deformation of geothermal reservoirs: A case study in the Hengill geothermal area using satellite geodesy 
    Juncu, Daniel (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2018-01)
    Deformation of geothermal reservoirs is a growing topic in the field of crustal deformation research. The deformation behavior of a geothermal resource can give us insight about its sustainability and can help to increase our understanding of reservoir ...

    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 ...

    A geophysical study of propagating rifts at the Bight-Transform Fault on the southern part of the Reykjanes Ridge and in the Eastern Volcanic Zone of Iceland 
    Benediktsdóttir, Ásdís (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-06-28)
    Iceland is located on the Mid-Atlantic Ridge and is the surface exposure of the ridge system on land. The influence of the plume has been shown to reach towards the south at least as far as the Bight Transform Fault. The ridge system in Iceland has ...

    The Jan Mayen microcontinent and Iceland Plateau: Tectono-magmatic evolution and rift propagation 
    Blischke, Anett (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-05-15)
    This study focused on the tectono-magmatic reconstruction of the Jan Mayen microcontinent (JMMC) and Iceland Plateau Rift (IPR) in context to the breakup and opening processes of the Northeast Atlantic region. Joint interpretation of densely spaced ...

    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, ...
