  • A Boussinesq type extension of the GeoClaw model - a study of wave breaking phenomena applying dispersive long wave models 
    Kim, Jihwan; Pedersen, Geir Kleivstul; Løvholt, Finn; LeVeque, Randall J. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The nonlinear shallow water model is widely used in the study of tsunami propagation, but an increasing number of studies are dedicated to the dispersion dynamics of tsunamis. If the wave dispersion becomes important, ...
  • Dispersion of tsunamis: does it really matter? 
    Glimsdal, Sylfest; Pedersen, Geir Kleivstul; Harbitz, Carl Bonnevie; Løvholt, Finn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    This article focuses on the effect of dispersion in the field of tsunami modeling. Frequency dispersion in the linear long-wave limit is first briefly discussed from a theoretical point of view. A single parameter, denoted ...
  • Effects of rotational submarine slump dynamics on tsunami-genesis – new insight from idealized models and the 1929 Grand Banks event 
    Zengaffinen, Thomas; Løvholt, Finn; Pedersen, Geir Kleivstul; Harbitz, Carl Bonnevie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Sediment slumps are known to have generated important tsunamis such as the 1998 Papua New Guinea (PNG) and the 1929 Grand Banks events. Tsunami modellers commonly use solid blocks with short run-out distances to simulate ...
  • Glacier and Permafrost Hazards 
    Wolken, Gabriel J.; Liljedahl, Anne K.; Brubaker, Michael; Coe, J.A.; Fiske, G.; Christiansen, Hanne H; Jacquemart, Mylene; Jones, Benjamin M.; Kääb, Andreas; Løvholt, Finn; Natali, Sue; Rudy, Ashley C A; Streletskiy, D. (Chapter / Bokkapittel / AcceptedVersion, 2021)
    Retreating glaciers and thawing permafrost are causing local- to regional-scale hazards that threaten lives and livelihoods, infrastructure, sustainable resource development, and national security. Permafrost hazards are ...
  • Granular porous landslide tsunami modelling – the 2014 Lake Askja flank collapse 
    Rauter, Matthias; Viroulet, Sylvain; Gylfadóttir, Sigríður Sif; Fellin, Wolfgang; Løvholt, Finn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Subaerial landslides and volcano flank collapses can generate tsunamis with devastating consequences. The lack of comprehensive models incorporating both the landslide and the wave mechanics represents a gap in providing ...
  • Modeling propagation and inundation of the 11 March 2011 Tohoku tsunami 
    Løvholt, Finn; Kaiser, Gunilla; Glimsdal, Sylfest; Scheele, Lasse; Harbitz, Carl Bonnevie; Pedersen, Geir Kleivstul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    On 11 March 2011 the Tohoku tsunami devastated the east coast of Japan, claiming thousands of casualties and destroying coastal settlements and infrastructure. In this paper tsunami generation, propagation, and inundation ...
  • Modelling 2018 Anak Krakatoa Flank Collapse and Tsunami: Effect of Landslide Failure Mechanism and Dynamics on Tsunami Generation 
    Zengaffinen, Thomas; Løvholt, Finn; Pedersen, Geir Kleivstul; Muhari, Abdul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The 2018 Anak Krakatoa volcano flank collapse generated a tsunami that impacted the Sunda Strait coastlines. In the absence of a tsunami early warning system, it caused several hundred fatalities. There are ongoing discussions ...
  • Numerical simulation of impulse wave generation by idealized landslides with OpenFOAM 
    Rauter, Matthias; Hosse, L.; Mulligan, Ryan P.; Take, W. A.; Løvholt, Finn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Landslide tsunamis and impulse waves are hazardous events with severe socioeconomic impacts. A long standing problem with simulations of these events is the generation stage, where landslides and water interact. Depth-averaged ...
  • On the characteristics of landslide tsunamis 
    Løvholt, Finn; Pedersen, Geir Kleivstul; Harbitz, Carl Bonnevie; Glimsdal, Sylfest; Kim, Jihwan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    This review presents modelling techniques and processes that govern landslide tsunami generation, with emphasis on tsunamis induced by fully submerged landslides. The analysis focuses on a set of representative examples ...
  • Simulating run-up on steep slopes with operational Boussinesq models; capabilities, spurious effects and instabilities 
    Løvholt, Finn; Lynett, P.; Pedersen, Geir Kleivstul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Tsunamis induced by rock slides plunging into fjords constitute a severe threat to local coastal communities. The rock slide impact may give rise to highly non-linear waves in the near field, and because the wave lengths ...
  • Simulating tsunami propagation in fjords with long-wave models 
    Løvholt, Finn; Glimsdal, Sylfest; Lynett, P.; Pedersen, Geir Kleivstul (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Tsunamis induced by rock slides constitute a severe hazard towards coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the short-frequency and high-amplitude tsunamis in this environment ...
  • Some giant submarine landslides do not produce large tsunamis 
    Løvholt, Finn; Bondevik, Stein; Laberg, Jan Sverre; Kim, Jihwan; Boylan, Noel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Landslides are the second-most important cause of tsunamis after earthquakes, and their potential for generating large tsunamis depend on the slide process. Among the world's largest submarine landslides is the Storegga ...
