Failure processes in submarine landslides: a geomorphological approach
… bathymetric data and can significantly enhance submarine<br/>geomorphological investigations. The methods are applied to bathymetric data from the<br/>Storegga Slide, one of the largest known submarine landslides, to investigate three aspects<br/>of submarine mass movements: spreading, fractal …

Numerical modeling of submarine landslides and surface water waves which they generate
Underwater landslides are a common source of tsunamis in coastal areas. In this thesis, three numerical models are developed to simulate the coupling of submarine landslides and the surface waves which they generate. Three different rheologies of the submarine sediments are considered: a viscous …

Submarine landslide flows simulation through centrifuge modelling
Landslides occur both onshore and offshore. However, little attention has been given to offshore landslides (submarine landslides). Submarine landslides have significant impacts and consequences on offshore and coastal facilities. The unique characteristics of submarine landslides include large …

Geomorfologia del Margine Continentale della Sardegna meridionale
… canyons and channels and areas affected by big submarine landslides. The detailed morphometric analysis carried out for each system of canyons and channel offered further information on the evolution dynamics and on the state of activity of the margin. Were detected evidence related to uplift …

3D Structural and Stratigraphic Architecture of the Northwest Santa Barbara Basin and Implications for Submarine Landslide Generation
<p>Multiple submarine landslides have been previously documented on the north flank of the Santa Barbara Channel, and such failures are considered to be capable of generating local tsunamis hazards to the Santa Barbara region. 2D seismic-reflection datasets provide a general view of regional …

Landslide generated tsunamis : numerical modeling and real-time prediction
Submarine landslides can generate local tsunamis posing a hazard to human lives and coastal facilities. Two major related problems are: (i) quantitative estimation of tsunami hazard and (ii) early detection of the most dangerous landslides. This thesis focuses on both those issues by providing …

Structure, Stratigraphy and Hydrocarbon Potential of the Colombian Caribbean Margin and Tsunamigenic Hazards in the Western Caribbean and the South China Sea
… exploration potential. I also characterize the submarine landslide related tsunami hazard of the western Caribbean region and for the South China Sea. In Chapter 2, I identify and map three giant (>1000’s km3), Plio-Pleistocene submarine landslides along the Colombian subduction margin. To …

Physical Modelling of Instability in Granular Soils and Tsunami Hazards Associated with Coastal Slope Failures
Coastal mass failures such as submarine and subaerial landslides have the potential to create significant tsunami hazards. As an inherently coupled solid-fluid interaction problem, accurate assessment of these hazards requires an understanding of the triggering mechanisms of failure to predict the …
