What made thetsunami 2004 happen?

Answer 1

The 2004 tsunami was triggered by a massive undersea earthquake off the coast of Sumatra, Indonesia, which measured 9.1 to 9.3 on the Richter scale. This earthquake occurred along the boundary of the Indian and Australian tectonic plates, causing a significant displacement of the ocean floor. The sudden uplift of the seabed generated powerful waves that traveled across the Indian ocean, impacting multiple countries and resulting in widespread devastation and loss of life.
