Computational Aspects of Submarine Slide Generated Tsunami

Abstract

Submarine landslide is the most serious threat on both local and regional scales. Tsunami phenomenon induced by submarine slide has put us on the challenge in understanding from generation mechanism to propagation and coastal inundation and mitigating the risk from submarine slide generated tsunami. This research presents the numerical simulation methodology by Smooth Particle Hydrodynamics (SPH) to investigate the impact forces of tsunami waves with the aid of physical modeling. By using parallelSPHysics, it is a source code based on the SPH method to model nearly‐incompressible flows, including various physical processes. The conclusions may potentially be taken as guideline of mitigate the risk from tsunami wave.
