Hazard Exposure Vulnerability and Capacity

Disaster risk depends on more than a hazard.

About 20 minutes, plus any extended practice

Supplied materials

Paper and pencil; drawing or spoken answers are welcome.
Topic notes: Hazard: the potentially damaging natural event or process. Exposure: people or assets located where the hazard could affect them. Vulnerability: conditions making exposed people or assets more susceptible to harm. Capacity: resources or capabilities supporting response and resilience.
Original exercise cards: Fictional region faces river flooding. / Fictional homes are located in the mapped flood zone. / Fictional exposed homes have easily damaged structures. / Fictional community has maintained warning and support systems. / A fictional road lies along the exposed coast. / A fictional population lacks usable evacuation access. / A fictional plan includes usable shelters and transport. / A fictional coast faces storm surge.

Learn the idea

Disaster risk depends on more than a hazard. Exposure concerns who or what is in its path; vulnerability concerns susceptibility to harm; capacity concerns available means to respond. A flood map and a population map answer different questions. These fictional cases teach distinctions, not real emergency instructions or a safety certification.

Hazard: the potentially damaging natural event or process. Exposure: people or assets located where the hazard could affect them. Vulnerability: conditions making exposed people or assets more susceptible to harm. Capacity: resources or capabilities supporting response and resilience.

Find the relevant physical feature or spatial relationship, then compare it with the four place descriptions. These exercise cards are original classroom prompts, not quotations or archival documents. The historical notes describe actual topics; invented situations are explicitly called fictional. A correct match needs a reason from the notes, not just a guessed label.

Read the actual topic notes and identify the facts or rule needed for this question.
Work through the solved analysis, distinguishing observations, interpretations and evidence limits.
Solve the new main case: show the relevant sequence, calculation, mechanism, institutional relationship or source comparison before choosing.
Complete the distinct practice cases and state which further evidence would be needed for a broader claim.

Worked example

See the method in action

Worked analysis: Two fictional neighborhoods face the same flood hazard, but one has more exposed homes and weaker usable evacuation access. First, separate the supplied facts and the question each can answer. Then compare the relevant rule, relationship or scope. Shared hazard does not imply equal risk. Exposure and vulnerability differ, while capacity can alter response. A hazard map alone cannot certify safety. Compare who is exposed, susceptible and supported rather than only the hazard’s presence.

Helpful tips

Compare who is exposed, susceptible and supported rather than only the hazard’s presence.
Keep the four distinctions separate: Hazard, Exposure, Vulnerability, Capacity. Use a complete reason rather than copying only a title.

See the answer and explanation

Equal hazard does not establish equal risk because exposure and response capacity differ.

Hazard concerns the event; exposed homes and usable response routes concern consequences and capacity. Comparing only probability omits these differences.

Take it further

Write a short response to a new classroom draft claiming that the worked analysis proves a universal result. Use two distinct supplied facts from this lesson, give a supported conclusion, and identify the extra evidence needed for the draft’s broader claim. Expected reasoning: Shared hazard does not imply equal risk. Exposure and vulnerability differ, while capacity can alter response. A hazard map alone cannot certify safety. A valid response names the scope and does not invent a quotation, date, measure or achieved result.

1. Compare the supplied original classroom notes: A — A fictional road lies along the exposed coast. B — A fictional population lacks usable evacuation access. Which interpretation preserves both facts?A concerns conditions making exposed people or assets more susceptible to harm; B concerns people or assets located where the hazard could affect them.Both concern only people or assets located where the hazard could affect them.Both concern only conditions making exposed people or assets more susceptible to harm.A concerns people or assets located where the hazard could affect them; B concerns conditions making exposed people or assets more susceptible to harm.

Keep the conclusion within the stated examples; do not add a universal ranking or unstated causal result.

2. Read this supplied card: “A fictional plan includes usable shelters and transport.” A writer adds, “This one example proves that every person and society has the same experience.” Which revision keeps what the card supports?The one example proves the same experience for every person and society.Reject the specific evidence completely because it does not describe everyone.Replace the stated feature with “the potentially damaging natural event or process”, even though that is a different feature.Keep the specific supported feature: resources or capabilities supporting response and resilience. Do not extend one example to every person or society.

3. Original classroom brief combines two notes: Fictional region faces river flooding. / Fictional exposed homes have easily damaged structures. Its draft wrongly treats them as identical. Which corrected comparison is supported?The first concerns the potentially damaging natural event or process; the second concerns conditions making exposed people or assets more susceptible to harm. They are distinct features.The first concerns conditions making exposed people or assets more susceptible to harm; the second concerns the potentially damaging natural event or process.Both establish only the potentially damaging natural event or process.Both establish only conditions making exposed people or assets more susceptible to harm.
