A tsunami is a seismic sea wave caused by a submarine earthquake that propagates outwards from the earthquake's epicentre (the point on the Earth's surface directly above the earthquake's focus).

So if you question was "where was the earthquake (epicentre) located?", then it was about 150 miles of Northern Sumatra in the Andaman-Sumatran subduction zone.

If you meant "what locations were affected by the tsunami??" then as the tsunami spread radially from the epicentre, then the following countries in and around the Indian Ocean (in no particular order) were affected to varying degrees;
Indonesia, (which probably suffered the largest loss of life), Sri Lanka (also hit extremely hard), Thailand, (which probably received the most attention since it had the highest death toll of Westerners and was the most filmed.), Malaysia, Myanmar (Burma), Bangladesh, the south-eastern coast of India, the island groups of Andaman and Nicobar, Maldives and Seychelles, and as far as the western Indian Ocean and the east African coasts of Somalia, Kenya and Tanzania.
