  • Global Hazards
    • Hazard vs Disaster
      • Disasters
        • Hazard becomes reality
          • Event causes death and damage to property and environments
      • Hazards
        • Natural event with potential of threatening life and property
    • Types of Hazard
      • Geophysical
        • Geological processes
        • Volcanoes
        • Earthquakes
        • Landslides / Avalanches
      • Hydro-meteorological
        • Atmospheric and hydrological processes
        • Floods
        • Droughts
        • Storms, eg. Tropical Cyclones
    • Disaster Risk Equation
      • R = (H x V)/C
      • Risk refers to the likelihood of hazards affecting us
      • Vulnerability refers to how susceptible a population is to damage
        • Eg. Population density and geographical location
      • Risk of disaster increases if:
        • Hazard frequency or severity increases
        • Vulnerability increases
        • Decreased capacity to cope
      • Shows that events of similar magnitude can cause different disaster levels
    • Trends
      • Hydromet. hazards increasing, geophysical staying the same
        • Global warming increase
      • Number of disasters increasing
        • Physical Reasons
          • Global Warming
          • El Nino events
        • Human Reasons
          • Population Growth
          • Poverty
          • Resource exploitation, eg. deforestation
      • Deaths are decreasing, economic losses increasing
        • Less Deaths
          • Prediction, Prevention, Prepared
