Simulation of Tsunami Wave Generated by Submarine Slide: Generation, Propagation, Run-Up and Impact

Abstract

Submarine slides can trigger tsunamis with high affecting offshore structures, subsea facilities and human lives along the shoreline. Unfortunately, slide-generated tsunami is a difficult problem due to the source of sliding of mass failure by itself or by the other earthquakes. There are no effective numerical model that could simulate simultaneously all stages of generation, propagation, run-up and impact of tsunami phenomena. Physical understanding of slide tsunami hazards is very poor. We must understand substance of tsunami clearly and how to find methods to reduce damage from tsunami wave. This paper will present a parallel computing based on ParallelSPHysics, it can simulate a comprehensive model of tsunami wave by using Smooth Particle Hydrodynamics method.
