Hazards EXIT Mapping multi-hazard zones Task A multi-hazard zone is an area of the world that is exposed to two or more major hazards. Using the map below annotate areas of the world that are regularly exposed to hazards. Create your own key to illustrate each of the major hazards. Start off by thinking about events in recent memory and then use the table at the bottom to complete some internet-based research.

Hazards EXIT Measuring risk People living in areas of high physical exposure to hazards and with high levels of human vulnerability will be the most at risk. These people are mostly found in the poorest parts of the world. High risk, high security (e.g. California) High risk, low security (e.g. Haiti, Mali, Bangladesh) Low risk, high security (e.g. UK) Low risk, low security (e.g. Bolivia, Angola) Physical exposure to hazards (risk) Human vulnerability to disaster (insecurity) A-LEVEL GEOGRAPHY TEACHING AND LEARNING RESOURCES
