Far field tsunami simulation using an open boundary condition from an extended domain

This study assesses the simulation of far field tsunami from an extended domain along coastal belt Southern Thailand and west coast Peninsular Malaysia using a formulated open boundary condition. The vertically integrated depth averaged shallow water equations are solved numerically in two different model domains. Along with original (OD) (ED) is considered during process. Using method lines technique, linear (SWE) all together to simulate response source western side domain. A similar 2004 Indian Ocean Tsunami as initial condition for this value problem. ED up 2000 km coast. non-linear where was omitted. In domain, used which by amplitude imposed at OD compute absence source. Finally, effect simulated south part Malaysia. travelled time elevation location stimulated models. outputs compared available data USGS website, very reasonable agreement observed.
