Abstract: This paper describes a computationally efficient, fast and accurate model to simulate tsunami generation, propagation and inundation. Tsunamis are simulated using the non-linear shallow water wave (NSWE) model in both the Spherical and the Cartesian coordinate system to simulate trans-oceanic wave propagation and inundation. The NSW equations are solved using a finite volume based shock capturing algorithm. The positivity preserving algorithm accurately preserves the steady �C� state of the NSWE equations. The solver is implemented on GPGPUs (General-Purpose computing on Graphics Processing Unit) using NVIDIA's Compute Unified Device Architecture (CUDA) programming platform. The model has been successfully verified and validated with analytical, experimental and field cases. In this paper, the model validation is summarized against the benchmark cases provided by the National Tsunami Hazard Mitigation Program (NTHMP) of National Oceanic and Atmospheric Administration (NOAA) USA. The validation cases include analytical solutions, laboratory experiments and field data
