    Earthquake Sequence 1973–1996 in Bárðarbunga Volcano: Seismic Activity Leading up to Eruptions in the NW-Vatnajökull Area 
    Bjarnason, Ingi Þorleifur (Iceland Glaciological Society and Geoscience Society of IcelandJöklarannsóknafélags Íslands og Jarðfræðafélags Íslands, 2014)
    A day and a half after the earthquake (mb=5.3, MS=5.6, MW=5.6) in the Bárðarbunga central volcano on Sept. 29th 1996, a volcanic eruption broke out under the Vatnajökull glacier. The eruption was located approximately 20 km SSE of the earthquake ...

    Seismic evidence for a tilted mantle plume and north–south mantle flow beneath Iceland 
    Shen, Yang; Solomon, Sean C.; Bjarnason, Ingi Þorleifur; Nolet, Guust; Morgan, W.Jason; Allen, Richard M.; Vogfjörð, Kristín; Jakobsdóttir, Steinunn; Stefánsson, Ragnar; Julian, B.R.; Foulger, G.R. (Elsevier BV, 2002-04)
    Shear waves converted from compressional waves at mantle discontinuities near 410- and 660-km depth recorded by two broadband seismic experiments in Iceland reveal that the center of an area of anomalously thin mantle transition zone lies at least 100 ...

    Seismic ground vibrations give advanced early-warning of subglacial floods 
    Eibl, Eva; Bean, Christopher J.; Einarsson, Bergur; Pálsson, Finnur; Vogfjörd, Kristín S. (Springer Science and Business Media LLC, 2020-07-21)
    Glacier runoff and melt from volcanic and geothermal activity accumulates in glacier dammed lakes in glaciated areas around the world. These lakes eventually drain, creating hazardous subglacial floods that are usually only confirmed after they exit ...

    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, ...

    Temperature and melting of a ridge-centred plume with application to Iceland. Part II: Predictions for electromagnetic and seismic observables 
    Kreutzmann, A.; Schmeling, Harro; Junge, A.; Ruedas, T.; Marquart, G.; Bjarnason, Ingi Þorleifur (Oxford University Press (OUP), 2004-12)
    The dynamic and melting processes of a ridge-centred plume have been investigated in a companion paper by Ruedas et al. (hereafter referred to as Paper I) in a set of 3-D numerical fluid dynamic models with varying plume excess temperatures and melt ...

    Tomographic image of the Mid-Atlantic Plate Boundary in southwestern Iceland 
    Bjarnason, Ingi Þorleifur; Menke, William; Flóvenz, Ólafur G.; Caress, David (American Geophysical Union (AGU), 1993-04-10)
    The 170 km South Iceland Seismic Tomography (SIST) profile extends from the west and across the Mid‐Atlantic Ridge spreading center in the Western Volcanic Zone and continues obliquely through the transform zone (the South Iceland Seismic Zone) to the ...
