  • Natural Hazards
    • What is a natural hazard?
      • A natural process which could cause death, injury or disruption to humans, or destroy property and possessions.
    • Types of natural hazard
      • Geological
        • Caused by land and tectonic processes
        • Eg, volcanoes, earthquakes, avalanches, landslides.
      • Meteorological
        • Caused by weather and climate
        • Eg, tropical storms, heatwaves, cold spells, climate change
    • 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
      • 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
