Nonlinear mechanism of tsunami wave generation by atmospheric disturbances
The problem of tsunami wave generation by variable meteo-conditions is discussed. The simplified linear and nonlinear shallow water models are derived, and their analytical solutions for a basin of constant depth are discussed. The shallow-water model describes well the properties of the generated tsunami waves for all regimes, except the resonance case. The nonlinear-dispersive model based on ...
متن کاملComparison between three-dimensional linear and nonlinear tsunami generation models
The modeling of tsunami generation is an essential phase in understanding tsunamis. For tsunamis generated by underwater earthquakes, it involves the modeling of the sea bottom motion as well as the resulting motion of the water above it. A comparison between various models for three-dimensional water motion, ranging from linear theory to fully nonlinear theory, is performed. It is found that f...
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 کاملevaluating the potential for tsunami generation in southern iran
makran subduction zone (msz) offshore of iran and pakistan is one of the most tsunamigenic sources in the indian ocean. historically, the msz has generated some tsunamigenic earthquakes like that of 28 november 1945 with the death tool of more than 4000 people along the coasts of iran, pakistan, india, and oman. in this study, the tsunami hazard associated with the msz is investigated. at first...
متن کاملTsunami Generation by Submarine Mass Failure
Numerical experiments are conducted for two-dimensional model problems of tsunami generation by underwater slides and slumps. These problems consist of a semi-ellipse, translating down an incline with a prescribed center of mass motion. For each problem, this motion is derived as a function of geometric and material parameters, and we calculate corresponding characteristic tsunami amplitudes. L...
