This study demonstrates the skills of D-FLOW Flexible Mesh (FM) and SFINCS (Super-Fast INundation CoastS) in combination with Delft Dashboard Tsunami Toolbox to numerically simulate tsunami offshore propagation inundation based on example 2011 T?hoku Japan. Caused by a megathrust earthquake, this is one most severe events recent history, resulting vast devastation Japanese coast. The comparison...

Tsunamis induced by rock slides constitute a severe hazard towards coastal fjord communities. Fjords are narrow and rugged with steep slopes, and modeling the shortfrequency and high-amplitude tsunamis in this environment is demanding. In the present paper, our ability (and the lack thereof) to simulate tsunami propagation and run-up in fjords for typical wave characteristics of rock-slide-indu...

Non-breaking tsunami waves run-up on steep slopes can cause severe damages to coastal structures. The estimation of the wave run-up rate caused by tsunami waves are important to understand the performance and safety issues of the breakwater in practice. In this paper, an Incompressible Smoothed Particle Hydrodynamics method (ISPH) method was utilized for the 2DV numerical modeling of nonli...

Karymskoye caldera lake is a nearly circular body of water with a diameter of approximately 4 km and a depth of up to 60 m. The sublacustrine, Surtseyan-type eruption in the lake on 2–3 January 1996 included a series of underwater explosions. A field survey conducted the following summer showed signs of tsunami wave runup around the entire coastline of the lake, with a maximum of 29 m runup at ...

The tsunami science and engineering began in Japan, the country the most frequently hit by local and distant tsunamis. The gate to the tsunami science was opened in 1896 by a giant local tsunami of the highest run-up height of 38 m that claimed 22,000 lives. The crucial key was a tide record to conclude that this tsunami was generated by a "tsunami earthquake". In 1933, the same area was hit ag...

The Chicxulub crater is the site of an asteroid impact linked with Cretaceous-Paleogene (K-Pg) mass extinction at ∼66 Ma. This struck in shallow water and caused a large tsunami. Here we present first global simulation tsunami from initial contact projectile to propagation. We use hydrocode model displacement water, sediment, crust over 10 min, shallow-water ocean that point onwards. was up 30,...

The 2011 Tohoku earthquake (Mw = 9.1) highlighted previously unobserved features for megathrust events, such as the large slip in a relatively limited area and the shallow rupture propagation. We use a Finite Element Model (FEM), taking into account the 3D geometrical and structural complexities up to the trench zone, and perform a joint inversion of tsunami and geodetic data to retrieve the ea...

We derive fully nonlinear, weakly dispersive model equations for propagation of surface gravity waves in a shallow, homogeneous ocean of variable depth on the surface of a rotating sphere. A numerical model is developed for the weakly nonlinear version of the model based on a combined finite-volume and finitedifference method with a fourth-order MUSCL-TVD scheme in space and a third-order SSP R...

Natural tsunami catastrophes occurred over the years have developed the interest in studying the associated physical phenomena in order to refine existing modeling tools and enhance alert mechanisms. To this purpose, it is essential to carry out an adequate risk analysis for the most exposed areas and therefore to study any historical event that may provide useful indications on the dynamics of...

The problem of generation and propagation of tsunami waves is mainly focused on plane beach, there are very few analytical works where wave generation is considered on non-uniformly sloping beach and as a result those works might have failed to capture important facts which are influenced by bottom-slope of the beach. Some researchers provided solution to the forced long linear waves but on a b...
