Event Information

On December 26, 2004, an earthquake in the Indian Ocean caused a devastating tsunami that tragically claimed the lives of around 230,000 people and affected 14 countries. This event marked the first major global disaster of the 21st century and remains one of the deadliest in recent history.

The lessons learned by the survivors, such as recognizing the warning signs of a tsunami and the importance of seeking high ground, have been engraved in their memories. However, as we approach the 20th anniversary of the disaster, a new generation who either experienced it at a very young age, or were born after the event can benefit from these lessons that the older survivors have learned.

This year’s World Tsunami Awareness Day theme aligns with the International Day for Disaster Risk Reduction, and the Summit of the Future, focusing on "youth and future generations." The activities planned for the observance aim to commemorate the 20th anniversary of the Indian Ocean Tsunami by passing on its lessons to a new generation of children and youth.

UNDRR is urging countries at risk from tsunamis to update evacuation routes, install new warning systems, and raise awareness among children and youth. They also encourage youth and learning institutes to play and learn from the Stop Disasters online game to understand how to save lives during disasters.
