World Tsunami Awareness Day (WTAD) 2025  

Tsunamis are infrequent, but when they strike coastal populations, the damage can be catastrophic – in lives, livelihoods and economic loss.

The theme supports global messaging on recognising natural tsunami warning signs, moving immediately to high ground or inland when needed, knowing local evacuation routes, preparing household emergency plans, taking part in community drills, and helping people who may require additional support, including children, older persons, persons with disabilities and tourists.

How to survive a Tsunami

The theme aligns with the final stretch of Sendai Framework implementation to 2030, with the Early Warnings for All initiative, and with the continued expansion of the UNESCO-IOC Tsunami Ready Recognition Programme.

In many tsunami scenarios, waves may arrive before official warnings do.

An unusual rise or recession of the sea
A loud ocean roar
Move immediately to high ground

Preparedness is power: Knowing an evacuation route, agreeing on a family meeting point, keeping essential supplies ready and taking part in drills builds readiness through simple actions practised regularly.


Early warnings save lives when people can act on them: Warning systems, science and technology matter, and they translate into safety when warnings are trusted, understood and acted upon quickly.


Inclusive preparedness protects everyone: Reaching persons with disabilities, children, older persons, tourists and migrants with clear, accessible planning extends protection to those most at risk of being left behind.


Community resilience begins with individual readiness: When neighbours, teachers, shopkeepers, hotel staff and local leaders know what to do, the entire community becomes safer.

Facts and Figures

230,000
The 2004 Indian Ocean tsunami remains the deadliest on record More than 230,000 people died across 14 countries – a scale of loss that continues to inform global tsunami preparedness policy despite the hazard’s infrequency.
14 countries
5 of 2,900
Preparedness education and drills save lives: the “Kamaishi Miracle” (2011) Only 5 of approximately 2,900 elementary and junior-high students in Kamaishi City, Japan, died when the tsunami triggered by the Great East Japan earthquake struck. No child at school that day died, an outcome attributed to sustained tsunami education and frequent evacuation drills.

Early warning delivers a strong return on investment Global analysis estimates US$4–36 billion in annual benefits for roughly US$1 billion invested each year in modern early warning, including approximately 23,000 lives saved annually.
US$1 billion invested each yearUS$4–36 billion in annual benefits
20%
Universal warnings cut losses Providing universal access to early warnings for storms, floods and tsunamis can reduce asset losses by up to 20%, preventing about US$13 billion in damage annually, with well-being gains of around US$22 billion per year.

Update

A tsunami warning is a race against time. A wave triggered close to shore can arrive within minutes, and when a volcano or landslide is the source, systems designed around earthquakes may register the threat late or not at all.
