        • Avalanches
      • 2. Metearological
        • caused by weather and climate
        • tropical storms
        • heatwaves
        • climate change
    • Factors that affect hazard risk
      • Vulnerability
        • more people in areas exposed to natural hazards more vulnerability
          • eg Bangladesh, high pop density
      • Capacity to cope
        • HIC cope better than LIC, can afford to evacuate people, build flood defences
      • Nature of natural hazards
        • Type, eg tropical storms can be predicted
        • Untitled
        • Frequency, some occur more often
        • Magnitude, more severe ones cause greater effects
