• Disaster risk is the chance or likelihood of suffering

  harm and loss as a result of hazardous event. It closely

  depends upon the exposure of a person community to

  hazard.
• Disaster risk is also defined as the probability or

  harmful consequences or expected losses (death,

  injuries, properties, economic disrupted or damaged)
• Risk = Chance (c) × Loss (l)

  
• The output of risk analysis is usually an estimation

  of the risk scenarios. The potential disaster losses in lives,

  health status, livelihoods, assets and services.
• Risk = Probability (p) × Loss (l)

  
• Risk may also depend on exposure to the

  consequences or un certainty or potential deviations from

  what planned, or expected disruption to everyday life.
• Disaster risk can be expressed as a function of HAZARD

  X VULNERABILITY or function (hazard, exposure,

  vulnerability). The equation:
• Disaster Risk = (DisRi)

  Hazard = (Haz)

  Elements of Exposure = (EoE)

  Vulnerability = (Vul)

  (DisRi) = (Haz) × (EoE) × (Vul)
