Hazard, Risk and Vulnerability Analysis

Identifying and understanding the risks a community may face allows emergency managers to prevent or significantly reduce the impacts and consequences of hazards. The purpose of Hazard, Risk and Vulnerability Analysis (HRVA) is to help community leaders make risk-based choices to address vulnerabilities, mitigate hazards and prepare for response and recovery from emergencies. A completed Hazard Risk and Vulnerability Analysis (HRVA) provides a comparison of any risks that may exist within a community. A ‘risk’ is a combination of a hazard or threat impact and the likelihood of its occurrence.  

The HRVA report is the foundation document for any community emergency program and is ideally completed before the strategic plan or any emergency response and recovery plans are written. Comparing risks is a requirement mandated by the Local Authority Emergency Management Regulation. Section 2(1) of this regulation requires local authorities to prepare emergency plans that reflect the local authority's assessment of the relative risk of occurrence and the potential impact on people and property of the emergencies or disasters.

To assist local authorities, EMBC has a HRVA toolkit and the EMBC  Online HRVA tool.
