- Caused by weather and climate
- Eg, tropical storms, heatwaves, cold spells, climate change
- Geological
- Factors affecting hazard risk from natural hazards
- Vunerability
- More people in areas exposed to natural hazards, the greater the probability they will be affected by a natural hazard
- Higher hazard risk
- More people in areas exposed to natural hazards, the greater the probability they will be affected by a natural hazard
- Capacity to cope
- The better a population can cope with a natural hazard, the lower the theat
- HICs able to cope better because they can afford defences, evacuation and repair
- Nature of natural hazards
- Type
- The hazard risk from some hazards is greater than others
- Frequency
- Some hazards occur more often than others
- Increasing hazard risk
- Magnitude
- More severe hazards cause greater effects than less severe hazards
- Type
- Vunerability
