Examining actual hazard analyses conducted by state and local emergency management programs in the United States shows that a variety of methods of quantitative or quasi-quantitative methods are in use:

… Rating each hazard by the number of key factors that are present in the hazard,

… Assigning a spread of points to each key factor and then using the cumulative value as the basis for rating, and

… Using mathematical formulas to represent the interactions between the various factors in the hazard.

The following three slides provide examples of how these methods might be applied to a scenario using the factors previously used to characterize a hazard in this lecture. Obviously very different factors could be used by a locality conducting this process based on differing needs and requirements.
