- Global Hazards
- Hazard vs Disaster
- Disasters
- Hazard becomes reality
- Event causes death and damage to property and environments
- Hazard becomes reality
- Hazards
- Natural event with potential of threatening life and property
- Disasters
- Types of Hazard
- Geophysical
- Geological processes
- Volcanoes
- Earthquakes
- Landslides / Avalanches
- Hydro-meteorological
- Atmospheric and hydrological processes
- Floods
- Droughts
- Storms, eg. Tropical Cyclones
- Geophysical
- 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
- Physical Reasons
- Deaths are decreasing, economic losses increasing
- Less Deaths
- Prediction, Prevention, Prepared
- Less Deaths
- Hydromet. hazards increasing, geophysical staying the same
- Hazard vs Disaster
