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.
