7. Capacity to Cope Nature of Hazard Vulnerability
Hazard risk is the probability (chance) that a natural hazard occurs.
There are several factors affecting hazard risk:
Capacity
to Cope
Nature of
Hazard
Vulnerability

8. 1. The type of hazard is important
1. The type of hazard is important. The hazard risk from some hazards is greater than others. For example, tropical storms can be predicted, but earthquakes happen suddenly without warning.
2. The more people that are in areas exposed to natural hazards, the greater the probability they will be affected by a natural hazard – so the hazard risk is higher.
3. A rich country will be much more likely to be able to afford to build defences against hazards like flood defences.
4. Natural hazards have to affect human activities to count as a hazard. The better a population can cope with an extreme event the lower the threat.
5. An area with a high population density living on a flood plain (like Bangladesh) is very vulnerable to flooding caused by extreme weather.
6. Frequency – Some natural hazards occur more often than others, increasing the hazard risk.
7. Higher Income Countries (HICs) are better able to cope with hazards.
8. Rich countries can afford to evacuate people from hazards.
9. Magnitude – The more severe natural hazards cause greater effects than less severe natural hazards. For example a large 9.0 magnitude earthquake may cause more damage than a 5.8 magnitude one.
10. An area with a high population density living in a city at the base of a volcano (like Naples in Italy) is very vulnerable to volcanic eruptions.
11. Rich countries will be able to afford to repair the damage afterwards.
12. Poor countries will spend money on other things such as education and hospitals.
