    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.
