Study Notes
Vulnerability and Exposure
- Vulnerability refers to the characteristics and circumstances that make a community or asset susceptible to hazards.
- Exposure indicates the likelihood of elements at risk experiencing hazard events of differing magnitudes.
Main Elements Exposed to Hazard
- Physical elements: Tangible aspects such as landscapes, inhabitants, buildings, and other structures occupying space.
- Socioeconomic elements: Factors influencing lifestyle, well-being, community peace, and livelihood during disasters.
- Environmental elements: Ecosystems and natural processes vulnerable to disaster effects.
Factors of Vulnerability
- Proximity to hazards: Geographic data helps identify locations prone to hazard events.
- Demography: Population density can lead to overcrowding, heightening vulnerability.
- Material resource capacity: Access to basic services is vital for effective disaster prevention and response.
- Institutional codes and policies: Existing structures may exacerbate community vulnerability.
- Cultural practices: Norms and beliefs can influence the community's openness to disaster prevention strategies.
Types of Hazards
- Natural Hazards: Caused by environmental processes beyond human control, like earthquakes and floods.
- Man-made or Technological Hazards: Result from human activities and typically occur in inhabited areas.
Impacts of Hazards
- Magnitude: Extent of impact measured through scientific instruments.
- Frequency: How often a hazard occurs within a specific area.
- Duration of impact: Varies depending on the type of hazard and affected elements.
- Causality of events: Impact severity is influenced by the extent of element involvement during a hazard.
Impact of Hazards on Different Exposed Elements
- Physical elements: Infrastructure such as roads and buildings suffer damage from hazards.
- Socioeconomic elements: Hazards can threaten livelihood and health, with some instances producing positive outcomes.
- Environmental elements: Ecosystems and organisms initially experience catastrophic effects from hazards.
