Tsunami modeling of a submarine landslide in the Fram Strait
[1] The present geological setting west of Svalbard closely parallels the situation off mid-Norway after the last glaciation, when crustal unloading by melting of ice induced very large earthquakes. Today, on the modern Svalbard margin, increasing bottom water temperatures are destabilizing marine gas hydrates, which are held in continental margin sediments consisting of interlayered contourite...
متن کاملUnderwater Landslide Shape, Motion, Deformation, and Tsunami Generation
We study underwater landslide shape, motion and deformation at early times. We present experimental and numerical results in a search for general behaviors of tsunamigenic underwater landslides. Our experimental work presents a granular mass moving and deforming down a steep incline. Our numerical work uses a Bingham-like fluid model (BING) to simulate more realistic underwater landslide models...
متن کاملLandslide tsunami case studies using a Boussinesq model and a fully nonlinear tsunami generation model
Case studies of landslide tsunamis require integration of marine geology data and interpretations into numerical simulations of tsunami attack. Many landslide tsunami generation and propagation models have been proposed in recent time, further motivated by the 1998 Papua New Guinea event. However, few of these models have proven capable of integrating the best available marine geology data and ...
متن کاملQuadtree-adaptive tsunami modelling
The well-balanced, positivity-preserving scheme of Audusse et al, 2004, for the solution of the Saint-Venant equations with wetting and drying, is generalised to an adaptive quadtree spatial discretisation. The scheme is validated using an analytical solution for the oscillation of a fluid in a parabolic container, as well as the classic Monai tsunami laboratory benchmark. An efficient database...
متن کاملTsunami Modelling using the Well-Balanced Scheme
A well balanced numerical scheme based on stationary waves for shallow water flows with arbitrary topography has been introduced by Thanh et al. [18]. The scheme was constructed so that it maintains equilibrium states and tests indicate that it is stable and fast. Applying the well-balanced scheme for the one-dimensional shallow water equations, we study the early shock waves propagation toward...
