Definition: Extensive disaster risk
The risk of low-severity, high-frequency hazardous events and disasters, mainly but not exclusively associated with highly localized hazards.
Annotation: Extensive disaster risk is usually high where communities are exposed to, and vulnerable to, recurring localized floods, landslides, storms or drought. Extensive disaster risk is often exacerbated by poverty, urbanization and environmental degradation.

About the terminology
The Open-ended Intergovernmental Expert Working Group on Indicators and Terminology (OIEWG) relating to disaster risk reduction was established by the General Assembly in its resolution 69/284 for the development of a set of possible indicators to measure global progress in the implementation of the Sendai Framework for Disaster Risk Reduction 2015-2030, coherent with the work of the Inter-Agency and Expert Group on Sustainable Development Goal Indicators. The report was adopted by the United Nations General Assembly on February 2nd, 2017.
The Sendai Framework Terminology on Disaster Risk Reduction promotes a common understanding and usage of disaster risk reduction concepts and to assist the disaster risk reduction efforts of authorities, practitioners and the public.
