World Tsunami Awareness Day

November 5, 2022

Image of a cresting sea wave with the words "Know how to recognize a tsunami, and what to do save your life".

In 2015 the United Nations declared that each year 5 November would be observed as World Tsunami Awareness Day – a reminder that when a tsunami strikes, everyone must be ready to get to high ground.

Tsunamis can be deadly, but they needn’t be. Early warning and early action are effective tools to protect people, saving lives, and preventing the hazard from becoming a disaster.

To be effective, tsunami early-warning systems must cover every at-risk person, they must be multi-hazard, and communities must be prepared so they can act quickly.

Graphic with quote: No one should be left behind when a tsunami strikes.

5 November 2022 is #TsunamiDay – a reminder that when a tsunami hits, everyone must be ready to #GetToHighGround
