The Indian Ocean tsunami wasn't located in a specific place, but rather originated in a specific location and affected a vast area.

Here's the breakdown:

* Origin: The 2004 Indian Ocean tsunami was triggered by a massive undersea earthquake off the coast of Sumatra, Indonesia.

* Affected Area: The tsunami's impact extended across the entire Indian Ocean, reaching coastlines of 14 countries including:

* Indonesia

* Sri Lanka

* India

* Thailand

* Myanmar

* Malaysia

* Somalia

* Tanzania

* Kenya

* Seychelles

* Maldives

* Bangladesh

* South Africa

* Oman

It's important to remember that the Indian Ocean tsunami wasn't a single event, but rather a series of massive waves that spread out from the epicenter of the earthquake.
