HRVA Component #2 – Risk Risk = likelihood + consequence Risk also considers exposure Frequency Ratings:
Likelihood Frequency Certain Every 2 years or more frequently Likely Every 3-10 years Possible Every 11-50 years Unlikely Every 51-100 years Rare Less than once every 100 years
Economic Environment Physical Social
e.g. bridges, pipelines
e.g. homeless, commuters
e.g. limited credit, farm land
e.g. forests, coastlines
Gathering Hazard Data
Documents: old HRVA documents and emergency plans, other risk assessments completed within the region, historical archives and news articles, external data sources (e.g., Canadian Disaster Database).
People: Elders and other community members who have access to oral or written historical records on past disasters, subject matter experts within and external to the community.
HRVA Component #4 – Impact
HRVA Step #4 – Impact Analysis 1. Review the ratings for each vulnerability. 2. Determine and rate the components of impact for each hazard or area.
HRVA Component #3 – Vulnerability
Risk Avoidance: a decision to effectively remove the exposure and/or sources of a risk or remove oneself from a risk (Government of British Columbia, 2016). Risk-Based Decision Making: making risk reduction choices based on the acceptability of consequences and the frequency of hazards (Government of British Columbia, 2004). Risk Evaluation: the process of examining a risk in terms of a cost/benefit analysis and evaluating whether it is an “acceptable” risk based on the needs and concerns of stakeholders (Government of British Columbia, 2016). Risk Identification: the process of finding and describing risks. Risk Management: the application of disaster reduction policies and strategies to prevent new risk, reduce existing risk, and manage residual risk (United Nations, 2016).
Risk Matrix: depicts clusters of risks, which influence risk-based decision making, and in turn contributes to priority-setting. Risk Profile: an analysis of a risk, its likelihood, possible impact, prioritization, and proposed mitigation strategies (Public Safety Canada, 2018). Risk Reduction: a decision to implement strategies to reduce the impact of a risk to an acceptable level. Risk Tolerance: the willingness of a community to accept or reject a given level of residual risk. Risk Transfer: a decision to shift some or all of the risk to another entity, asset, system, network, or geographic area, making impacts easier to bear (Government of British Columbia, 2016).
Frequency ratings chart: Emergency Management BC, 2019. Risk assessment steps: British Columbia Ministry of Public Safety and Solicitor General, 2003.
Likelihood Periods: historic, current, future HRVA Step #2 – Risk Assessment 1. Risk identification 2. Risk analysis 3. Risk evaluation
HRVA Component #1 – Hazard Types of Hazards: natural hazards; diseases, pest infestations, and epidemics; human-caused hazards. HRVA Step #1 – Hazard Identification 1. Identify hazards for a community and define characteristics. 2. Identify potential multi-hazard events. 3. Obtain data on identified hazards.
HRVA COMPONENTS & PROCESSES
HRVA Step #3 – Vulnerability Analysis 1. Review the vulnerability factors for each hazard. 2. Rate each factor on whether the community is high or low in resilience.
RISK GLOSSARY
Risk: the combination of the likelihood that a hazard will occur and the severity of potential impacts to health, property, the environment, and other assets, for a specific time period and location (Emergency Management BC, 2019). Risk Acceptance: a decision to do nothing and accept the risk and its potential impacts (Government of British Columbia, 2016). Risk Adaptation: a decision to prepare for and adjust to a risk, with the goal of reducing harm; achieved by reducing vulnerabilities or increasing resilience. Risk Analysis: the systemic use of information to estimate the likelihood and severity of injury or loss to people, property, the environment, or other assets (Government of British Columbia, 2016). Risk Assessment: a qualitative or quantitative approach to identify, analyze, and evaluate a risk.
HRVA Step #5 – Resilience Planning 1. Create goals. 2. Identify strategies for building resilience.

Hazard Risk Analysis (HRA) Hazard Resilience Index (HRI) Aboriginal Resilience Index (ARI) A community’s hazard identification – a hazard risk profile that outlines hazards likely to occur in a community and the underlying risk factors. Steps: 1. Decide on which hazards you will start with. 2. Consider dividing your community into
zones. 3. Rate the factors for each hazard. 4. Highlight factors that are important to your
community. 5. Rate your community’s hazard risk level. 6. Complete the Hazard Risk Profile template. 86 hazards organized into 17 categories: accidents, astronomical, atmospheric, conflictual social action, contamination, dam failure and structural collapse, diseases, earthquakes/ tsunamis/volcanoes, fires, food shortages, geological hazards, hazardous material spills/explosions/ gas leaks, hydrological (water and snow) hazards, nuclear failure, power and water outages, riots, terrorism.
A community’s resilience assessment – a tool to assess a community’s resilience in the face of locally identified hazard-risk priorities. Steps: 1. Decide on which hazards you will start with. 2. Rate the factors for each hazard. 3. Highlight factors that are important to your
community. 4. Rate your community’s overall resilience for
each hazard. 5. Complete the Integrated Resilience Profile
template.
A tool to build a disaster resilience plan – to assess a community’s current resilience and areas of resilience that can be enhanced. Two categories of resilience: Community resources – examples include: • Close-knit and involved • Self-sufficient and resourceful • Has a strong health and social support
system Disaster management – examples include: • Disaster-aware • Has a comprehensive disaster plan • Has adequate first response capacity Steps: 1. Select an indicator for each characteristics. 2. Highlight characteristics that are important
to your community. 3. Rate your community’s resilience level. 4. Complete the Integrated Disaster
Resilience Profile template.

Resilience: the ability of a system, community, or society exposed to hazards to resist, absorb, accommodate, adapt to, transform, and recover from the effects of a hazard in a timely and efficient manner, including through the preservation and restoration of its essential basic structures and functions through risk management (Emergency Management BC, 2019). Resilience Planning: creating goals and identifying strategies for building resilience in a community. Storytelling: a method of collecting traditional knowledge, which can emphasize important life lessons and sustain culture and traditions. Talking Circle: a method of collecting traditional knowledge, in which a group discussion discusses a topic in an egalitarian and non-confrontational manner. Traditional Knowledge: a type of local knowledge, embedded in the cultures and traditions of Indigenous communities, that rests on the premise that humans are holistically interconnected with everything else (e.g., plants, animals, elements of nature and the land, the spirit world), and that humans have a responsibility (to past, present, and future generations) to foster healthy persons and communities. (Justice Institute of British Columbia, 2016). Underlying Disaster Risk Drivers: processes or conditions, often development-related, that influence the level of disaster risk by increasing levels of exposure and vulnerability or reducing capacity. Vulnerability: the conditions determined by economic, environmental, physical, and social factors, or processes which increase the susceptibility of an individual, a community, assets, or systems to the impacts of hazards (United Nations Disaster Risk Reduction, 2015). Vulnerability Assessment: assessing the susceptibility of harm of identified hazards, in relation to areas of vulnerability (i.e., people, property, infrastructure, environment, or other assets), taking in to consideration the capacity for response and recovery, which may have an effect on those vulnerabilities.
Geographic Information Systems (GIS): a computer-based tool that analyzes, stores, manipulates, and visualizes geographic information on a map, in order to visualize patterns and understand relationships and trends; includes analytic and cartographic applications (GIS Dictionary, 2018). Hazard: a source of potential harm, or a situation with a potential for causing harm, in terms of human injury; damage to health, property, the environment, and other assets; or some combination of these (Emergency Management BC, 2019). Hazard Identification: gathering detailed information and defining the characteristics of hazards that could affect the community/organization. Hazard, Risk, and Vulnerability Analysis (HRVA): a comprehensive analysis of potential hazards, the risk that specific hazards will occur, possible vulnerabilities should specific hazards occur, and adverse impacts that a hazard may have on identified vulnerabilities. Hazard Scenario: a narrative description of a hypothetical emergency or disaster that may impact a community. Impact: the physical/ environment, psychosocial, economic, and political consequences or adverse effects that may occur as the result of a hazard; also referred to as consequence. Impact Analysis: determining the potential impact, damage, and/or loss caused by a hazard (Canadian Standards Association, 2017). Local Knowledge: a dynamic form of knowledge that people in a community have developed over time and is based on lived experiences. Mitigation: proactive actions or sustained efforts taken to reduce or eliminate the risk of a hazard occurring, reduce the impact, or transfer the risk.
Business Continuity Planning: a process that develops and documents procedures and arrangements that enable an organization to plan for and respond to incidents and business disruptions, in order to continue business operations as a predefined acceptable level (International Organization for Standardization, 2012). Business Impact Analysis (BIA): a process that identifies and evaluates the potential consequences of incidents and business disruptions on the business operations of an organization (International Organization for Standardization, 2015). Community Mapping: a visual representation of different HRVA components, such as a community’s resources, previous disasters, and resilience to future disasters. Community Vision: where a community envisions what a disaster resilient community would look like and a strategy to reach that vision. Continuous Improvement: reflecting upon lessons learned to continually improve practices and minimize problems from recurring. Critical Infrastructure: assets that are essential for the functioning of government and society (e.g., water, food, transportation, health, energy and utilities, safety, telecommunications and information technology, government, finance, and manufacturing. Disaster: an event that causes a serious disruption of the functioning of a community, and involves widespread losses and impacts that exceed the community’s ability to cope using its own resources. Emergency: a present or imminent event that requires prompt coordination of actions concerning persons or property to protect the health, safety or welfare of people, or to limit damage to property or the environment (Public Safety Canada, 2007). Exposure: people, property, systems, and other assets present in hazard zones, that are subject to potential losses and impacts.
