This is a simulation of the Indian Ocean tsunami that occurred on
26th December 2004 resulting from a magnitude 9.3 earthquake off the west coast of
Sumatra. The tsunami travels at great speed and reaches Sri Lanka in
just under two hours.
Lat: 27N - Lon: 72E The spatial domain (approx. 3500x3500 km) was divided into 250000 rectangular cells. The model was based on land topographic and sea bathymetric data obtained from the NDGC. The tsunami travels at great speed and reaches Sri Lanka in approx just under two hours. Wave speeds were calculated for each cell based on the appropriate celerity relationship at each point in the spatial domain. Coriolis effects were also included. The non-circular wave-fronts are clearly visible, which indicates curved rays. The earthquake was due to a 1200km long subduction rupture zone at around 5100m depth in the deepest part of the Java Trench. The subduction consisted of four segments, of lengths 220km, 410km, 300km and 350km respectively. The segments were modelled using physical data as reported by Watts, et al, WAVES, 2005. |

This documentary was uploaded on the tenth anniversary of the
2004 Boxing Day disaster as a reminder of the immense suffering that took place on
that fateful day. The Boxing Day Tsunami of 2004 was a singular event among disasters
and philanthropy. It reached us and connected us like no other. |
