When disasters strike and systems fail, one signal often stays on and returns first: radio

281 Hazards
Experts worldwide have created a comprehensive list of 281 hazards — ranging from earthquakes, tsunamis, and floods to pandemics, chemical accidents, and even extraterrestrial events like solar storms. This shared framework helps countries, policymakers, and communities develop stronger disaster risk reduction (DRR) strategies.
What's new
2024: Three Regional Platforms for Disaster Risk Reduction
From October to November, the Asia Pacific, Africa and Europe and Central Asia regional platforms will be held.
These are a key opportunity to tackle trans-boundary issues around disaster prevention and preparedness, provide leadership and direction, and propose relevant solutions to address disaster risk and to build the resilience of communities and nations.
Building on these, the Eighth session of the Global Platform for Disaster Risk Reduction (GP2025) will be held in June 2025.
From managing disasters to managing risk and safeguarding development
We envision a world where disasters no longer threaten the well-being of people and the future of the planet. Sustainable development and the 2030 Agenda cannot be achieved without working towards building resilience.



UNDRR is the lead UN agency for the coordination of disaster risk reduction
We help decision makers across the globe better understand and change their attitude to risk.

The Disaster Risk Communication Hub supports practitioners across sectors to plan and deliver public risk communication that helps people understand risk and take informed action.
