Living with Natural Hazards
What are the causes and effects of tropical storms and how do people prepare for and respond to them?

2. You need to be able to answer the following questions:
Describe the primary and secondary effects of tropical storms?
Why do the effects of tropical storms vary between LEDC’s and MEDC’s? Use case study examples.
What causes a tropical storm?
Where do tropical storms occur?
How do tropical storms form? (make sure you can include diagrams)
What can be done to reduce the effects of tropical storms? (include a range of strategies and examples – the use of GIS (geographical information systems), education programmes etc)
Why can some countries prepare better for tropical storms than others?
Why would some people think that tropical storms could happen more and in different locations in the future?
How could climate change influence the pattern of tropical storms in the future?

New Orleans and Levee repairs
The southern Gulf Coast of the United States bore the brunt of Katrina. Officials believe several thousand people may be dead.
Thousands of people have been made homeless in New Orleans. Some 80% of the city is flooded and there has been widespread looting. A complete evacuation of the city has been ordered.
The death toll in Mississippi is at least 100, while hundreds of houses and businesses - including dozens of waterfront casinos - have been destroyed. About a million homes are without electricity.
In Biloxi, one of the most seriously damaged towns, many casinos and businesses have been looted. The town of Gulfport has also been heavily damaged.
About 400,000 homes and businesses are without power in Alabama, while parts of the city of Mobile have been badly flooded.
In southern Florida, where the hurricane passed through on August, 100,000 homes and businesses are without electricity.
