Page  15  Risk : “Expected losses (of lives, persons injured, property damaged, and economic activity disrupted) due to a particular hazard for a given area and reference period. Based on mathematical calculations, Risk is the product of hazard and vulnerability”.  Where  Hazard : A threatening event, or the probability of occurrence of a potentially damaging phenomenon within a given time period and area  Vulnerability : Degree of loss resulting from a potentially damaging phenomenon. ----United Nations Department of Humanitarian Affairs, 1992 Risk Evaluation Method
