ABSTRACT

Shallow water equations were analyzed numerically for simulation of tsunami propagation from the source area to coastal zone of Mentawai Islands along West Sumatra Island. A triangular mesh was set for spatial discretization and a system of partial differential equation is reduced to a system of ordinary differential equations. Initial displacement based on Okada model was applied. Our numerical techniques were demonstrated with a simulation of tsunami generated from an earthquake with epicenter near South Pagai Island, Mentawai Islands, Indonesia.
