International Day for Disaster Risk Reduction

The International Day for Disaster Risk Reduction, known worldwide as the International Day for Disaster Risk Reduction, is observed on October 13.

The day was established by the United Nations General Assembly in 1989.

The purpose of this international observance is to send an important message to governments around the world, as well as to international organizations and the global population, encouraging reflection on the increasing frequency and severity of natural disasters.

The United Nations Office for Disaster Risk Reduction has chosen “Resilience Starts at Home” as the theme for the 2026 International Day.

ISPRA, as part of its institutional responsibilities for the collection, processing and dissemination of data and maps on hydrogeological instability covering the entire national territory, publishes the Report on Hydrogeological Instability in Italy every three years. The report constitutes the official reference framework for hydrogeological hazard and risk in Italy.

As highlighted in the latest report, presented in July 2025, 94.5% of Italian municipalities are exposed to risks from landslides, floods, avalanches and/or coastal erosion; 19.2% of the national territory is classified as being at higher risk from landslides and floods; 1.28 million people live in areas exposed to high or very high landslide hazard; and 6.8 million people are exposed to flood risk under the medium-probability flood hazard scenario, with return periods ranging from 100 to 200 years.

All data are made available to support prevention and risk mitigation efforts across the country.

As part of its technological innovation activities, the Institute promotes the testing of innovative technologies for landslide monitoring, such as photo monitoring based on photographic sensors capable of documenting changes in the territory over time. It also uses Artificial Intelligence to collect, analyse and archive information on landslides and to improve the accessibility and usability of information for citizens through the IdroGEO platform, by implementing a virtual assistant that interacts with users, providing information and answering questions about hydrogeological instability.
