The 'all hazards' approach that the Sendai Framework on Disaster Risk Reduction calls for ‘to strengthen technical and scientific capacity to capitalize on and consolidate existing knowledge and to develop and apply methodologies and models to assess disaster risks, vulnerabilities and exposure to all hazards;’ (paragraph 24 j)’ needed clarification.

Following extensive scientific consultation, the United Nations Office for Disaster Risk Reduction (UNDRR) and the International Science Council (ISC) published in 2020 the UNDRR/ISC Hazard definition and classification review. This was followed by the UNDRR/ISC Hazard Information Profiles: Supplement to UNDRR-ISC Hazard Definition & Classification Review–Technical Report (2021). This Supplement consists of a description of each of the 302 hazard information profiles (HIPs), which was developed using a consultative process by scientists and experts across the globe.

The UNDRR/ISC Hazard Information Profiles (HIPs) provide a common set of hazard definitions and other information relevant to informing the strategies and actions of governments and stakeholders, and for managing the risks associated with hazards. They can be used whenever and wherever for assessment, planning, and action related to hazards. As such, they relate to the design, implementation, and monitoring of disaster risk reduction and risk-informed investments at all levels.

The science-based structure of the HIPs serves to avoid confusion and duplication in the classification of hazards. It also promotes up-to-date information derived from the ‘data revolution, rigorous accountability mechanisms and renewed global partnerships’. The HIPs support the implementation of not only the Sendai Framework for Disaster Risk Reduction 2015-2030, but also the Sustainable Development Goals of Agenda 2030, the Paris Agreement and International Health Regulations (2005). In 2022 an International Science Council Policy Brief was published describing the use of UNDRR/ISC HIPs to manage risk and implement the Sendai framework for disaster risk reduction.
