Which Hazards, Which People: A Hazard Vulnerability Analysis for a Gulf Coast County
No health department can prepare equally for every possible disaster. A hazard vulnerability analysis ranks hazards by how likely they are and how much harm they would cause, and it asks which people would suffer most. This paper presents a hazard vulnerability analysis for a composite Gulf Coast county of 310,000 people and uses a social vulnerability index to identify neighborhoods where preparedness efforts should focus first.
Purpose
The analysis guides the health department's preparedness priorities, informs its emergency operations plan and supports grant applications. It also reflects the view that preparedness is a capability of whole systems and communities, which begins with assessing the risks their communities face and the populations that are most vulnerable (Nelson et al., 2007).
Method
A planning team from the health department, emergency management, hospitals, utilities and community organizations identified hazards from historical records, climate projections and regional industry. The team gave each hazard a 0-to-3 score for how likely it is, how badly it would hurt people, property and local business, and how well the county is already prepared; stronger preparedness lowers the final risk. Relative risk was calculated as probability multiplied by severity.
Results
The table summarizes scores for the five highest-ranked hazards.
| Hazard | Probability (0-3) | Human impact (0-3) | Property impact (0-3) | Preparedness gap (0-3) | Relative risk |
|---|---|---|---|---|---|
| Hurricane | 3 | 3 | 3 | 1 | High |
| Extreme heat | 3 | 2 | 0 | 2 | High |
| Riverine flood | 2 | 2 | 3 | 1 | Moderate |
| Chemical release from port facilities | 1 | 3 | 1 | 2 | Moderate |
| Pandemic respiratory disease | 1 | 3 | 0 | 2 | Moderate |
Interpreting the Ranking
Hurricanes ranked highest because they are likely and devastating. Extreme heat ranked nearly as high despite causing little property damage, because it occurs every summer, kills quietly and receives less planning attention than storms. The chemical release scenario, while unlikely, would demand rapid shelter-in-place or evacuation decisions and specialized medical response.
Social Vulnerability
Hazards harm people unequally. The social vulnerability index developed for disaster management combines census variables into four themes: socioeconomic status, household composition and disability, minority status and language, and housing type and transportation (Flanagan et al., 2011). Tracts with high scores have more residents who may lack the resources to prepare, evacuate or recover.
Mapping the County
Applying the index to the county's 72 census tracts identified eleven tracts in the highest quartile. These tracts had more older adults living alone, households without vehicles, residents with limited English and mobile homes. Seven of the eleven also lay within hurricane storm surge zones, placing them at the intersection of high hazard and high vulnerability.
Lessons From Katrina
Hurricane Katrina showed the deadly consequences of that intersection. An analysis of Louisiana deaths identified 971 Katrina-related deaths in the state; drowning caused 40%, and 49% of victims were aged 75 or older. In Orleans Parish, mortality among Black adults was 1.7 to 4 times higher than among White adults (Brunkard et al., 2008). The authors concluded that preparedness must focus on evacuating and caring for vulnerable people in hospitals, nursing homes and private homes.
Priority Actions
The analysis led to five priorities: a voluntary registry of residents needing evacuation help or electricity for medical devices; agreements with transit agencies to evacuate people without vehicles from high-vulnerability tracts; a heat response plan with cooling centers and check-ins for isolated older adults; multilingual warning messages; and a shelter-in-place education campaign near port facilities.
Limitations
Scoring relies on judgment, and different teams might rank hazards differently. Census data lag and may miss recent changes, such as new housing developments or displacement. The index identifies places, not individuals, so outreach must still reach specific people. The team plans to update the analysis every two years and after any major event. Scores for rare events, such as a chemical release, rest on expert judgment more than records, so the team documented its reasoning for each.
Engaging the Community
The planning team presented results at meetings in the eleven high-vulnerability tracts and asked residents what would help them prepare. Residents asked for evacuation information on local radio in Spanish and Vietnamese and for neighbors to be trained to check on older adults. These suggestions were added to the plan.
Climate Trends
Hazard rankings must look forward as well as back. Warmer seas are associated with stronger hurricanes, and rising temperatures are making extreme heat more frequent and longer. The planning team adjusted probability scores using regional climate projections, which raised the heat score and prompted earlier investment in heat planning.
Hospitals and Long-Term Care
Katrina's toll in hospitals and nursing homes, where patients died waiting for evacuation, made facility planning a priority. The analysis recommends that every hospital and nursing home in the surge zone have an evacuation plan with transport agreements, backup power and a way to share patient information with receiving facilities.
Linking Analysis to the Emergency Plan
Each high-ranking hazard now has an annex in the county's emergency operations plan with triggers, roles and resources. The hazard analysis is the reason each annex exists, and reviewing it every two years keeps the plan aligned with actual risks rather than with past events alone.
Data Sources for Scoring
Scores drew on flood insurance maps, hurricane landfall records, heat index records from the weather service, port hazardous materials inventories and pandemic planning assumptions. Recording sources for each score allows the next team to check and update the reasoning.
Mitigation Opportunities
Some risks can be reduced before any event. Elevating clinics and pharmacies above flood levels, installing backup power at dialysis centers and planting shade trees in hot neighborhoods lower vulnerability permanently. The analysis ranks such projects by the number of vulnerable residents they protect and their cost, giving the county a list ready for mitigation grants.
Sharing Results
A public summary of the analysis, with maps showing hazard zones and high-vulnerability tracts, was posted on the county website and shared with city councils. Transparency helps residents understand their own risks and builds support for mitigation spending.
Conclusion
A hazard vulnerability analysis focuses preparedness where risk is greatest. In the composite county, hurricanes and extreme heat ranked highest, and social vulnerability mapping identified neighborhoods where hazards and disadvantage overlap. Lessons from Katrina show that planning for the most vulnerable residents is not optional; it determines who survives.

MPH 520 Module 2 instructions, in plain terms
The MPH 520 catalog listing begins with identifying disasters and emergencies, and since the second module's instructions remain inside the course, this sample carries out a hazard vulnerability analysis. These assignments usually ask you to list the hazards a community faces, rank them with a stated method, identify vulnerable populations and recommend priorities. Check whether your instructor supplies a scoring template, such as a hospital-style hazard vulnerability tool, or expects you to design one. Explain each score's basis. Use a social vulnerability measure to locate people at highest risk, not only hazards. Draw on a past disaster to justify priorities. Say how often the analysis should be updated and who should take part.
Inside the MPH 520 Module 2 example
Roughly 1,000 words appear under seventeen headings, including a six-column scoring table. The paper states the purpose and method, presents results, interprets the ranking and introduces the social vulnerability index before mapping it to county tracts. Lessons from Katrina, priority actions, limitations and community engagement follow, along with climate trends, hospital and nursing home planning, links to the emergency operations plan, data sources, mitigation opportunities and public sharing of results. A margin comment beside the method explains that a stated scoring approach makes the ranking reproducible. The conclusion shows how the overlap of hazard and vulnerability determines where planning must focus. Scores in the table are explained in the text, hazard by hazard.
Where the marks sit in the MPH 520 Module 2 rubric
Hazard vulnerability papers are typically assessed on a clear, reproducible method, sensible scores, attention to vulnerable populations, evidence from past events and actionable priorities. Sources are the social vulnerability index paper, a study of Katrina deaths and an article defining preparedness, each formatted in APA. The scoring table shows every hazard's ratings. Vulnerability mapping moves the analysis from hazards to people. The Katrina section supplies evidence rather than assumption. Priorities are specific and tied to findings. A limitations section acknowledges subjectivity in scoring, and graders often reward that honesty. Clear notes on data sources for each score add credibility, and a map or tract list showing where hazards and vulnerability overlap makes the findings easy to use. Graders also notice when limitations are paired with a plan to update the analysis.
Common MPH 520 Module 2 mistakes, and how to avoid them
Students frequently list hazards without a method for ranking them, or rank them by impression. Others ignore social vulnerability, treating everyone as equally exposed. Describe your scoring scale and apply it consistently. Pull at least one census-based vulnerability measure. Make sure each priority follows from something in your results. If building a scoring table feels unfamiliar, a tutor can walk you through a simple probability-times-severity approach you can adapt. End by naming the neighborhood or group that most needs attention and why. Remember that a low-probability hazard with severe human impact can still deserve planning. Tables are easier to grade than long paragraphs of scores, so present ratings in one place and discuss them afterward. Name the data behind each probability score.
