A Hazard and Vulnerability Assessment (HVA) identifies the risk of potential disasters to a given facility in its location.  It is a tool used to clarify the most likely disasters that a facility faces.  It should include both natural and man-made disasters, as well as internal and external risks.  The following are samples of the many HVA's that can be found on the web:
