The issues with the use of Vulnerability
“The term ‘Vulnerability’ is now used in such a loose and widespread manner that it is in danger of becoming as useless as the term ‘Sustainability’, and so some precision is needed to rescue it.” (T. Cannon, 2006)

What is Element Vulnerability?
• Element Vulnerability refers to the degree of potential physical damage to the target elements at risk, such as a buildings, facilities, infrastructure, and lifelines in response to a hazard event of a given intensity.

What is System Vulnerability?
• System Vulnerability refers to the conditions determined by physical, social, economic, and environmental factors or processes, which increase the susceptibility of an anthropogenic system to the effect of hazards.
• System Vulnerability is the extrinsic property of an anthropogenic system that can be defined by the susceptibility, coping capacity, and resilience of the system.

Summary
• Vulnerability can be classified into Element Vulnerability and System Vulnerability.
• Vulnerability functions are created to calculate potential damage or loss to a given element at risk against a specified event intensity.
• System vulnerability provides a framework for identifying the social, economic, and environmental causes of disaster impacts. It directs attention to the underlying causes of vulnerability rather than to its result, the negative impacts.
