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. (Peer reviewed; Journal article, 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, ... -
Coupling of dispersive tsunami propagation and shallow water coastal response
Løvholt, Finn; Pedersen, Geir Kleivstul; Glimsdal, Sylfest (Journal article, 2010)The key issue of this article is the concept of combining a model dedicated to dispersive large scale propagation of tsunamis with ComMIT, developed and made freely available by NOAA, that is a state of the art tool for ... -
Dispersion of tsunamis: does it really matter?
Glimsdal, Sylfest; Pedersen, Geir Kleivstul; Harbitz, Carl Bonnevie; Løvholt, Finn (Journal article, 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 ... -
Earthquake related tsunami hazard along the western coast of Thailand
Løvholt, Finn; Bungum, Hilmar; Harbitz, Carl Bonnevie; Glimsdal, Sylfest; Lindholm, Conrad D.; Pedersen, Geir Kleivstul (Journal article, 2006)The primary background for the present study was a project to assist the authorities in Thailand with development of plans for how to deal with the future tsunami risk in both short and long term perspectives, in the wake ... -
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 (Peer reviewed; Journal article, 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 ... -
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, 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 (Peer reviewed; Journal article, 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 ... -
On the characteristics of landslide tsunamis
Løvholt, Finn; Pedersen, Geir Kleivstul; Harbitz, Carl Bonnevie; Glimsdal, Sylfest; Kim, Jihwan (Journal article, 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 (Peer reviewed; Journal article, 2013) -
Simulating tsunami propagation in fjords with long-wave models
Løvholt, Finn; Glimsdal, Sylfest; Lynett, P.; Pedersen, Geir Kleivstul (Journal article, 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 ... -
Stochastic analysis of tsunami runup due to heterogeneous coseismic slip and dispersion
Løvholt, Finn; Pedersen, Geir Kleivstul; Bazin, Sara; Kühn, Daniela; Bredesen, Rolv Erlend; Harbitz, Carl Bonnevie (Peer reviewed; Journal article, 2012)Most tsunami models apply dislocation models that assume uniform slip over the entire fault plane, followed by standard analytical models based on Volterra's theory of elastic dislocations for the seabed deformation. In ... -
Tsunami generation due to submerged blocks and deformable landslides involving retrogression
Løvholt, Finn; Kim, Jihwan; Harbitz, Carl Bonnevie; Pedersen, Geir Kleivstul (Lecture, 2015)
