Vulnerability
It is the measure of weakness of a community or group of people to cope with, resist or recover from the impacts of hazards.
A more vulnerable community is more susceptible to disasters. After effects of the hazards depend upon the vulnerability of the affected community.
Risk
Risk is the potential of loss, damage or destruction of an asset as result of hazard. Risk is the measure derived from the product of hazard and vulnerability.
Risk = hazard x vulnerability
i.e. If a community is more vulnerable to a hazard event, that community is at more risk.
Capacity
It is the strategies within the community to make them less vulnerable to hazards.
