General Classification of Hazards
- Natural Hazards
- Quasi-natural Hazards
- Technological (or human-made) Hazards
hazards that arise purely natural processes in the environment.
Natural Hazards
hazards such as smog or desertification that arises through the interaction of natural
processes and human activities.
Quasi-natural Hazards
hazards that arise directly as a result of human activities.
Technological (or human-made) Hazards
Types of Hazards (Hewitt and Burton, 1971)
- Atmospheric (Single Element)
- Atmospheric (Combined Element)
- Hydrologic
- Biologic
- Technologic
Other Ways of Classification of Hazard
- Natural Origin – geological, hydro/meteorological, biological, extra-terrestrial
- Anthropogenic Origin – fire, civil conflict, pollution, technological
- Environmental
- Socio-economic
- Political
- Security
Types of Hazard According to ONSET
- Sudden Onset - little or no warning
2. Slow Onset - event slow to develop
