2D as well as 3D models of the December Tsunami inundation [both in AVI and QT formats] are available in the above site.

The 3 d movie in Quick Time format [985 KB] can be downloaded alternatively from here.

This is the only simulation movie available on the Internet that shows visually the tsunami waves in 3 d inundating the shores of South India and Sri Lanka. We see the inundating waves spreading from Mahabalipuram in the north, to Kodiakkarai and Palk Strait in the south.


The preliminary simulation that produced this animation shows the propagation of the tsunami starting at 01.00 hours UTC. In the deep ocean the waves measure tens of centimetres in height. In the coastal areas however, these relatively small waves can increase up to 4 to 10 meters depending on the local topography and bathymetry.


Areas hit by high flood waves are shown in bright colours. Yellow and red colours indicate the worst hit areas. The simulation is carried out using the Delft3D simulation package of WL Delft Hydraulics.
