Retracing the tsunami rays

  • R. Shankar

Abstract

The propagation of the tsunami waves can be modelled with varying degrees of accuracy. The more accurate methods, which involve the numerical solution of the shallow water equations, are costly in terms of simulation times. With present day technology, the simulations are too slow for many of the requirements of a tsunami early warning system. The ray diagram technique is one where accuracy is sacrificed for computational speed. Also referred to as refraction diagrams, they were first used to analyse tsunami propagation by Kenji Satake (1; 2).
