Let’s celebrate World Tsunami Awareness Day on 5 November 2021!

Date: 28 October 2021

This year’s World Tsunami Awareness Day on 5 November promises to be special.

Tsunamis are the single most deadly of all sudden onset natural hazards. Millions of people live and work in tsunami-exposed communities across the whole global ocean.

With the launch of the UN Decade of Ocean Science for Sustainable Development 2021-2030 (the 'Ocean Decade'), the world has a once-in-a-lifetime opportunity to reduce tsunami risk around the world.

UNESCO's Intergovernmental Oceanographic Commission (IOC) has established the Ocean Decade Tsunami Programme and a Scientific Committee to draft a 10-year research, development, and implementation plan for this programme -  fully supported by the UN Office for Disaster Risk Reduction, UN agencies, civil protection agencies and other partners.

The Tsunami Programme will contribute to the Safe Ocean outcome of the Ocean Decade by making 100% of at-risk communities Tsunami Ready by 2030.

Scaling up the Tsunami Ready programme is a testament to what focused, effective international cooperation can deliver, and will make a significant contribution to reducing risk and saving lives.

Only together can science, governments and communities achieve this ambition.

Join events around the world to celebrate World Tsunami Awareness Day on 5 November.
