- Hazards, Vulnerability, Risk, Resilience and Disaster
- Disaster
- A serious disruption of the functioning of a community or a society involving widespread human, material, economic or environmental losses and impacts, which exceeds the ability of the affected community or society to cope using its own resources
- Economic losses of over $1.5 million
- Degg's Model
- Hazardous geophysical event + Vulnerable population
- Understanding Risk
- Unpredictability
- People are caught out by timing or magnitude
- Lack of Alternatives
- People stay in hazardous area due to lack of options
- Economic reasons
- Lack of space to move
- Lack of skills or knowledge
- Dynamic Hazards
- Cost-Benefit
- The benefits of a hazardous location may outweigh the risks
- Perception of risk
- "Russian Roulette Reaction"
- The acceptance of the risks
- The Hazard-Risk Formula
- Risk = Hazard x Exposure x Vulnerability / Manageability
- Disaster Risk and Age Index
- Ageing populations
- Children and the elderly suffer more from hazards
- The acceleration of risk
- Ageing populations
- Unpredictability
- The Pressure and Release Model
- Based on processes generating vulnerability and the natural hazard event
- Understanding the PAR Model
- Root causes
- Limited access to
- Power
- Structures
- Resources
- Ideologies
- Political systems
- Economic systems
- Limited access to
- Dynamic pressures
- Lack of
- Appropriate skills
- Training
- Local investment
- Press freedom
- Ethical standards
- Macro-forces
- Rapid population change
- Rapid urbanisation
- Deforestation
- Arms expenditure
- Debt repayment schedules
- Lack of
- Unsafe conditions
- Fragile physical environment
- Fragile local economy
- Vulnerable society
- Public actions
- Root causes
- The Social and Economic Impacts if Tectonic Hazards
- Impacts of earthquakes are greater than earthquakes
- Volcanoes are concentrated meaning only a small proportion of people are exposed to volcanic actiivity
- 5% of people are affected by earthquakes
- Economic impacts are proportional to the land area exposed
- Economic Impacts
- Level of development
- Insured impacts versus non-insured losses
- Total number of people affected
- The speed of economic recovery
- Degree of urbanisation
- Land value
- Disaster
