    The 2014 Lake Askja rockslide-induced tsunami: Optimization of numerical tsunami model using observed data 
    Gylfadottir, Sigridur Sif; Kim, Jihwan; Helgason, Jón Kristinn; Brynjólfsson, Sveinn; Höskuldsson, Ármann; Jóhannesson, Tómas; Harbitz, Carl Bonnevie; Løvholt, Finn (Wiley-Blackwell, 2017-05)
    A large rockslide was released from the inner Askja caldera into Lake Askja, Iceland, on 21 July 2014. Upon entering the lake, it caused a large tsunami that traveled about ∼3 km across the lake and inundated the shore with vertical runup measuring up ...

    Assessment of Landslide-Induced Geomorphological Changes in Hítardalur Valley, Iceland, Using Sentinel-1 and Sentinel-2 Data 
    Dabiri, Zahra; Hölbling, Daniel; Abad, Lorena; Helgason, Jón Kristinn; Saemundsson, Thorsteinn; Tiede, Dirk (MDPI AG, 2020-08-24)
    Landslide mapping and analysis are essential aspects of hazard and risk analysis. Landslides can block rivers and create landslide-dammed lakes, which pose a significant risk for downstream areas. In this research, we used an object-based image analysis ...

    Geological challenges and geohazard monitoring of a mega engineering hydropower project in Iceland 
    Sigtryggsdóttir, Fjóla G.; Snaebjornsson, Jonas Thor (Elsevier BV, 2019-09)
    Geohazards must be considered, assessed and mitigated for all life-cycle phases of most mega infrastructure projects. This paper presents a unique mega engineering project, the 600 MW Kárahnjúkar Hydropower Project in Iceland. The construction site ...

    Local knowledge of emerging hazards : Instability above an Icelandic glacier 
    Matti, Stephanie Alice; Ögmundardóttir, Helga (2021-05-01)
    Climate change is contributing to shifts in the magnitude and scale of hazards, and the emergence of risks in areas where they were previously unknown. In south-east Iceland, a fracture in the mountainside of Svínafellsheiði threatens to cause between ...

    Managing unprecedented risk: Unstable slopes in Iceland and Greenland 
    Matti, Stephanie Alice (University of Iceland, School of Social Sciences, Faculty of Sociology, Anthropology and Folkloristics, 2022)
    Climate change is contributing to shifts in the magnitude and scale of hazards, and the emergence of environmental risks in areas where they were previously unknown. In the Öræfi district of south-east Iceland, a fracture discovered by farmers gathering ...

    Molards as an indicator of permafrost degradation and landslide processes 
    Morino, Costanza; Conway, Susan J.; Saemundsson, Thorsteinn; Helgason, Jón Kristinn; Hillier, John; Butcher, Frances E.G.; Balme, Matthew R.; Jordan, Colm; Argles, Tom (Elsevier BV, 2019-06-15)
    Molards have been defined in the past as conical mounds of debris that can form part of a landslide's deposits. We present the first conclusive evidence that molards in permafrost terrains are cones of loose debris that result from thawing of frozen ...
