Introducing Hazards & Disasters
Objective:
To recognise the difference between risk and hazard and how both can interact to create a disaster event.
Starter: Ranking the top 10 Natural Disasters of all time. Download this crib sheet and card set & cut out the cards. First of all, rank the order of deaths. Then try the event and the year. Task 1 - Study the SlideShow Presentation underneath carefully and copy out the three Venn diagrams. Task 2 - Complete the worksheet titled 'Name That Hazard' from GATW (link here) Task 3 - Make a copy of the following in your book “A disaster is a sudden, calamitous event that causes serious disruption of the functioning of a community or a society causing widespread human, material, economic and/or environmental losses which exceed the ability of the affected community or society to cope using its own level of resources." |

For a disaster to be entered into the database of the UN's International Strategy for Disaster Reduction, at least one of the following criteria must be met:
Task 4 - Decide whether the following events are hazards or disasters and evidence the reasons why using this table worksheet.
Event 1 - Hurricane Xynthia
Event 2 - Extra Cold Weather - Alaska 2012
Event 3 - Floods in Brisbane 2011
Event 4 - Plague of Locusts in Africa
Event 5 - Multiple Tornado Outbreak 2011 USA
- a report of 10 or more people killed
- a report of 100 people affected
- a declaration of a state of emergency by the relevant government
- a request by the national government for international assistance (geographyalltheway.com)
