2025 Hazard Information Profiles (HIPs) online reference

A description of each of the 281 hazard information profiles (HIPs), developed using a consultative process by scientists and experts across the globe.

Following the recommendation for regular review and update, three years after their initial release, the UNDRR and the ISC undertook an update of the UNDRR-ISC HIPs: the revised publication is available now and the online resource below has been updated. A machine actionable data set will be available in the coming weeks.

The HIPs serve as a trusted source of scientifically grounded, standardized hazard information used by governments, agencies, researchers and educators worldwide. They support risk assessment, disaster preparedness, loss tracking and multi-sectoral planning. Above all, they are a practical resource – valued because they are usable, useful and used.

The Hazards Information Profiles and the Technical report provide an important resource to support the implementation of disaster risk reduction and risk-informed investment, aligned with the Sendai Framework for Disaster Risk Reduction 2015–2030, but also the Sustainable Development Goals of Agenda 2030, the Paris Agreement on Climate Change and the Addis Ababa Action Agenda on Sustainable Financing. It provides a common set of hazard definitions to Governments and stakeholders to inform their strategies and actions on risk reduction and management.

The HIPs support the development and updating of national and local disaster risk reduction strategies and loss databases, as well as integrating disaster risk reduction into national statistics, legal, accounting and regulatory frameworks and public and private policy, financing and investment decisions.

Aligned with the UNDRR-ISC Hazard Definition and Classification Review - Technical report, the 2025 HIPs are divided into eight hazard types. Each hazard type is further divided by cluster type and covers a variable number of specific hazards.

Background on the HIPs

Hazard information when combined with exposure, vulnerability and capacity is fundamental to all aspects of disaster risk management, from multi-hazard risk assessments for prevention dn mitigation to warnings and alerts, to disaster response and recovery, long-term planning and public awareness.

In 2019 the United Nations Office for Disaster Risk Reduction (UNDRR) and the International Sceince Council (ISC) jointly established a technical working group to identify the full scope of hazards relevant to the Sendai Framework as a basis for countries to review and strengthen their risk reduction policies and operational risk management practicies.

The Hazard Information Profiles (HIPs) are the result of this international collaborative effort and aim to fill gap by providing a systematic approach and standardised characterisation of hazards. The HIPs aim to contribute to a coherent view of hazards, which can support countries:

  • Report effectively on loss and damage;
  • Implement a comprehensive and inclusive approach to the development of disaster risk reduction strategies;
  • Develop and use multi-hazard early warning systems effectively and forecast events in the future.
