One hazard causes another hazard to occur (e.g.,earthquake leading to slope instability).
1
We build on an extensive body of work, particularly internationally recognised glossaries, to strengthen consensus across the hazard and risk community through a common understanding of multi-hazard, multi-risk terminology and concepts.
2
We propose draft multi-hazard, multi-risk indicators and a roadmap for testing their further development and application in disaster risk management.
3
We share key observations and recommendations for the application and evolution of terminology, applying the glossaries in our platform of quantitative and qualitative multi-hazard risk approaches, Disaster Risk Gateway.
Selected outputs
Glossary of 140 terms
- Terms relevant to multi-hazards, multi-risk management
- Terms relevant to interdisciplinary disaster risk research (MYRIAD-EU)
6 key sector descriptions
3 hazard interrelationships and related concepts
Two or more hazards may occur in the same region and/or time period with impacts different than their sum (e.g., storms leading to the occurrence of floods and landslide simultaneously).
One hazard can change the likelihood and/or magnitude of additional hazards in the future (e.g., drought increases the likelihood of wildfires)
4 KEY REFLECTIONS
- 1
Evolution of terminology. Emerging definitions are captured through the Disaster Risk Gateway.
- 2
Terminology and definitions matter. Establishing a common understanding is central to successful interdisciplinary research and practice.
- 3
Indicators could be used to drive progress towards multi-hazard, multi-risk management.
- 4
When is it helpful to include ‘multi-’as a prefix? We question whether part of the paradigm shift is through inherently seeing disaster risk through the lens of multiple, interrelated hazards.
3 groups of multi-hazard risk indicators
Multi-risk characterisation
Multi-risk preparedness
Multi-risk management and governance
