RISK is generally defined as the expected impact caused by a particular phenomenon. It combines the likelihood or possibility of a disaster happening and the negative effects that result if the disaster occurs. Risk is hazard multiplied by vulnerability less the capacity of the population to cope. Risk is defined as the probability of a damaging event or circumstance.
Vulnerability is the extent to which an individual, community, sub group, structure, service or geographical area is likely to be damaged by the impact of a particular disaster. The factors that influence vulnerability include physical, economical, social, political, technical, idealogical, cultural, ecological, institutional and organisational.

- Exposure: It is the degree of risk of an event experienced in daily life from the probability of a hazard to actual occurrences of events of all sizes.
- Resilience: It is the ability to recover, ranging in degree from simply achieving stability at any level of functioning to recovering the full range of resources and positive momentum that existed prior to the event
- Resistance: It is the ability to withstand the impacts and continue to function.
