Natural Hazards

The best definition of the relationship between a natural hazard and a natural disaster is:

• A natural disaster occurs in the northern hemisphere whereas a natural hazard occurs in the southern hemisphere
• They are the same thing
• A natural hazard is the potential of an incident occurring whereas a natural disaster is declared when there has been loss of human life or property damage
• A natural disaster is more extreme than a natural hazard

Which type of hazard are those which are associated with our weather and climate?
