Epicenter of 2004 Indian Ocean earthquake , just north of Simeulue Island.

Note that although the epicenter of the earthquake was at this precise point source, about 1200 km of faultline slipped in total, in an arc curving northwards along the Nicobar Islands and Andaman Islands , and the resulting tsunamis were generated along this entire arc rather than from this point source.

Note the precise longitude and latitude shown in the caption have since been adjusted slightly by the USGS.
