I think it was the Tsunami in 2004.
The most destructive, if not the largest, tsunami ever recorded was the Sumatra tsunami known as the Boxing Day 2004 tsunami, on 26 December 2004. An earthquake off the west coast of Sumatra in Indonesia sent a deadly tsunami across the Indian Ocean and smaller waves into the Pacific (and Southern) Ocean. The wave caused deaths or damage in Indonesia, Malaysia, Thailand, Burma, Bangladesh, India, and on the coast of Somalia in Africa.

The 2004 tsunami was one of the most devastating due to its massive scale, affecting multiple countries across the Indian Ocean region. It was triggered by a powerful undersea earthquake, resulting in massive tsunamis that caused widespread destruction and loss of life. The lack of adequate warning systems and preparedness in many areas contributed to the high death toll.
