• Disaster is a sudden, calamitous event, bringing great damage loss, destruction and devastation to life and property
• Disaster is a serious disruption of the functioning of society, causing widespread human material or environment losses, which exceed the ability of the affected people to cope, using their human resources
• Disasters are emergencies that cannot be handled by those affected without outside assistance.
• An event, either human-made or natural, becomes a disaster when it is sudden or progressive, causing widespread human, material or environmental losses.
• Disaster Risk is expressed as the likelihood of loss of life, injury or destruction and damage from a disaster in a given period of time
• Vulnerability most often associated with poverty, but it can also arise when people are isolated, insecure and defenceless in the face of risk, shock or stress
• physical, social, economic and environmental are the 4 different types of vulnerabilities
• physical vulnerability is a human-made environment
• environmental vulnerability is a natural environment
• social vulnerability is the susceptibility of the population, the social institutions or organizations, communities, and society
• economic vulnerability is the assets and resources of the community that are susceptible to disasters, including the production, distribution, and utilization of goods and services that ensure the well-being of the people
• there are three types of hazard, natural hazards, human-induced hazards, and deliberately planned by humans
• Hazards are potentially damaging physical events, phenomena or human activities that may cause injury or loss of life, damage to property, social and economic disruption, orenvironmental degradation
• Natural Hazards are beyond human control.
• Human-induced Hazards may be due to accidents, carelessness,or inability to implement protective measures.
• deliberately planned by humans
• history construction. In this method, the existing hazards andthe disasters that the community experienced areidentified.
• Hazard and Vulnerability Mapping. Areas in the community that are vulnerable to a specific hazard are identified then located in the map.
• Factor Analysis the tool describes the characteristics of the hazard
• Terms of analysis are the following : frequency, duration, speed of onset, intensity, probability, forewarning, manageability
