    Hekla Volcano, Iceland, in the 20th Century: Lava Volumes, Production Rates, and Effusion Rates 
    Pedersen, Gro; Belart, Joaquín M. C.; Magnússon, Eyjólfur; Vilmundardóttir, Olga Kolbrún; Kizel, Fadi; Sigurmundsson, Friðþór Sófus; Gísladóttir, Guðrún; Benediktsson, Jon Atli (American Geophysical Union (AGU), 2018-02-22)
    Lava flow thicknesses, volumes, and effusion rates provide essential information for understanding the behavior of eruptions and their associated deformation signals. Preeruption and posteruption elevation models were generated from historical stereo ...

    Historical lava flow fields at Hekla volcano, South Iceland 
    Pedersen, Gro; Montalvo, Jorge; Einarsson, Páll; Vilmundardóttir, Olga Kolbrún; Sigurmundsson, Friðþór Sófus; Belart, Joaquín M. C.; Hjartardottir, Asta Rut; Kizel, Fadi; Rustowicz, Rose; Falco, Nicola; Gísladóttir, Guðrún; Benediktsson, Jon Atli (Iceland Glaciological Society and Geoscience Society of IcelandJöklarannsóknafélags Íslands og Jarðfræðafélags Íslands, 2018)
    Hekla volcano is known to have erupted at least 23 times in historical time (last 1100 years); often producing mixed eruptions of tephra and lava. The lava flow volumes from the 20th century have amounted 80% to almost 100% of the entire erupted ...

    Long or short silicic magma residence time beneath Hekla volcano, Iceland? 
    Sigmarsson, Olgeir; Bergþórsdóttir, Ingibjörg A.; Devidal, Jean-Luc; Larsen, Guðrún; Gannoun, Abdelmouhcine (Springer Nature, 2022-01-07)
    Timescales of magma transfer and differentiation processes can be estimated when the magma differentiation mechanism is known. When conventional major and trace element analyses fail to distinguish between various processes of magma differentiation, ...

    Magma fragmentation and tephra dispersal in explosive eruptions: The 1991 and 1845 Hekla eruptions 
    Guðnason, Jónas (University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017-07-12)
    Iceland is one of the most volcanically active terrestrial regions on Earth. Hazards posed from volcanic eruptions to local population and life stock is well known in Iceland and the wider effects from volcanic activity have been elevated in recent ...

    Of mosses and men: Plant succession, soil development and soil carbon accretion in the sub-Arctic volcanic landscape of Hekla, Iceland 
    Vilmundardóttir, Olga Kolbrún; Sigurmundsson, Friðþór Sófus; Pedersen, Gro; Belart, Joaquín M. C.; Kizel, Fadi; Falco, Nicola; Benediktsson, Jon Atli; Gísladóttir, Guðrún (SAGE Publications, 2018-10-07)
    Lava flows pose a hazard in volcanic environments and reset ecosystem development. A succession of dated lava flows provides the possibility to estimate the direction and rates of ecosystem development and can be used to predict future development. We ...
