We can logically classify hazards in the same way we classify disaster events. As a hazard exists because it may result in a disaster, it makes sense to view that hazard as natural, human systems based, or conflict based. It is important to understand that a hazard is a potential cause of a disaster. Not every hazard will result in a disaster, but every disaster will result from a hazardous condition, whether or not that condition was recognized in advance of the event.
