S. Neetu and D. Shankar simulated tsunami based on the tidal model of Unnikrishnan et al. (Proc. Ind. Acad. Sci. (Earth Planet. Sci.), volume 108, pp. 155-177, 1999). The forcing was by an initial perturbation (25 m) of the sea surface along an arc in the vicinity of the earthquake epicentre (3.4 N, 95.7 E.) and the Andaman and Nicobar Islands. The model resolution was about 9 km (5 minutes) and the ETOPO5 bathymetry was used. The simulation runs for 10 hours.
