What this dot point is asking
SEAB wants you to explain why people continue to live in areas at risk from earthquakes, volcanoes and tsunamis. The central insight is that hazardous areas often offer real benefits, fertile soils, resources, energy, jobs and tourism, and that people weigh these against the risk, which they often perceive as low or unlikely, so for many the advantages of staying outweigh a danger that feels distant.
The answer
The benefits that attract people
Tectonically active areas, especially around volcanoes, offer genuine attractions:
- Fertile volcanic soils: weathered volcanic ash and lava break down into rich soils that give high crop yields, drawing farmers to volcanic slopes.
- Valuable minerals: volcanic areas can contain minerals and metals worth mining.
- Geothermal energy: the Earth's heat near volcanoes can be tapped to generate electricity and provide heating.
- Tourism: dramatic volcanoes, hot springs and scenery attract visitors, creating jobs and income.
Social and economic ties
Beyond physical benefits, people stay because of strong ties to a place:
- Family and community: people are reluctant to leave their home, relatives and community.
- Livelihoods: their jobs, farms or businesses are located there, and moving means losing income.
- Cost of moving: relocating and buying new land or housing elsewhere is expensive, and for poorer people often unaffordable.
Perception of risk
How people judge the risk strongly affects their decision, and perceived risk can differ from actual risk:
- Many people see a major eruption or earthquake as rare and unlikely to affect them, especially if none has happened in living memory.
- Some trust that warning systems, defences or preparation will protect them.
- Because the benefits are immediate and certain while the hazard feels uncertain and infrequent, people often decide the advantages are worth the risk.
Why poorer people may have little choice
The poorest often have the least choice: they cannot afford to move, depend on local farmland or jobs to survive, and have few safer options, so they remain in the most exposed places, which is part of why disasters hit the poor hardest.
Examples in context
Example 1. Farming on the slopes of Mount Merapi, Indonesia. Despite being one of the most active volcanoes in the world, Mount Merapi's fertile volcanic soils support dense farming communities on its slopes, growing rice and vegetables with high yields. Generations of families depend on this land and remain even after deadly eruptions, illustrating how fertile soils, livelihoods and deep ties keep people in a clearly hazardous place.
Example 2. Geothermal energy and tourism in Iceland. Iceland sits on a divergent boundary, yet its population thrives by turning the hazard into a resource: geothermal energy heats homes and generates electricity, and volcanic landscapes, hot springs and geysers draw large numbers of tourists. It shows how the benefits of a tectonic setting, cheap clean energy and tourism income, can make living with the risk not just tolerable but advantageous.
Try this
Q1. State two benefits of living near a volcano. [2 marks]
- Cue. Fertile volcanic soils that give high crop yields, and resources such as valuable minerals or geothermal energy for electricity and heat; tourism income is also acceptable.
Q2. Explain why poorer people may have little choice but to live in a hazardous area. [2 marks]
- Cue. They cannot afford the cost of moving and buying land or housing elsewhere, and they depend on the local farmland or jobs for their livelihood, so leaving would mean losing their means of survival.
Q3. Explain how a low perception of risk encourages people to stay in a hazardous area. [2 marks]
- Cue. If people judge a major hazard as rare and unlikely to affect them, especially when none has happened recently, the certain everyday benefits of living there feel more important than a danger that seems distant, so they choose to remain.
Exam-style practice questions
Practice questions written in the style of SEAB exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Original6 marksMany people live close to active volcanoes despite the dangers. (a) Explain three reasons why people continue to live in these areas. (b) Suggest why poorer people in particular may have little choice but to stay.Show worked answer →
(a) Three reasons: first, volcanic areas often have very fertile soils, formed from weathered volcanic ash and lava, which give high crop yields and attract farmers. Second, volcanoes provide resources such as valuable minerals and, in some places, geothermal energy that can generate electricity and heat. Third, volcanoes can attract tourists, creating jobs and income from visitors who come to see the scenery, hot springs and the volcano itself.
(b) Poorer people may have little choice but to stay because they cannot afford to move and buy land or housing elsewhere, they depend on the local farmland or jobs for their livelihood, and they may have strong family and community ties. They may also believe an eruption is unlikely in their lifetime or feel they have no safer option.
Markers reward three clear benefits (fertile soil, minerals or geothermal energy, tourism) and sound reasons the poor are constrained (cost of moving, dependence on local livelihood, ties, limited options).
Original5 marksExplain how people's perception of risk affects their decision to live in a hazardous area.Show worked answer →
Perception of risk is how people judge the likelihood and seriousness of a hazard, which may differ from the actual risk. If people perceive the risk as low, they are more likely to stay.
Many people perceive tectonic hazards as rare and unlikely to affect them personally, especially if no major event has happened in living memory, so the everyday benefits of living there (good soil, jobs, home, community) outweigh a danger that feels distant. Some trust that warning systems, defences or their faith will protect them.
Because the benefits are immediate and certain while the hazard feels uncertain and infrequent, people often decide the advantages are worth the risk, and so continue to live there. A low perceived risk therefore encourages people to stay even where the real danger is high.
Markers reward the idea that perceived risk can differ from actual risk, and that a low perception of risk (hazard seen as rare or survivable) leads people to stay because the benefits feel more certain than the danger.
