Numerical simulations of Tsunami generation by using Boussinesq equations
The Boussinesq equations are used to study the nonlinear processes of Tsunamiss generation and propagation. Induced by submarine landslides and slumps, Tsunami has been investigated firstly using simple source models in linear wave theory under assumption of potential flow theory. The surface waves computed by the linear wave theory and by the numerical solution of the linearized Boussinesq equations for the case of submarine smoothly raised slides are compared, indicating good performance of the proposed model on simulating the beach deformation. With a specified section of Okinawa trench, scenarios of the Tsunami waveforms induced by bottom deformation, from their generation in deep sea to shallow water, are simulated. The relations between the earthquake magnitude and Tsunami waveform are discussed.
