Vulnerability analysis is the systematic process of identifying, assessing, and understanding the weaknesses or conditions that make individuals, communities, infrastructure, systems, or environments susceptible to hazards and their harmful consequences. In risk assessment, vulnerability is concerned not only with the presence of a hazard but also with the degree to which exposed elements are likely to suffer damage or loss. For example, two communities exposed to the same flood may experience very different impacts because of differences in housing quality, income, preparedness, access to healthcare, and emergency services. Thus, vulnerability analysis helps determine why some people or systems are more severely affected by hazards than others. Vulnerability generally has several dimensions. Physical vulnerability relates to the location, design, construction, and condition of buildings, infrastructure, and other physical assets. Social vulnerability includes factors such as age, health, gender, disability, social exclusion, education, and access to support networks. Economic vulnerability is associated with poverty, employment, livelihood dependence, savings, insurance, and the capacity to recover from losses. Environmental vulnerability concerns
