Task Two

 

Use the table above to plot the track of Hurricane Katrina. If you download Hurricane Katrina Track Placemarks A and L - they have already been done for you. If you search for "24.7°N 76.7°W" Google Earth will take you to the location of placemark B.

Place all the placemarks in a single folder.

 
Research

Task Three

The following bulletin was released before Hurricane Katrina struck the Gulf Coast and New Orleans. Add placemarks for all the locations in bold. For each location you should add a description of why that location is mentioned in the bulletin.

Task Four

Download and open in Google Earth the 'Where they were found Google Earth Overlay'. Can you identify any clusters of deaths caused by Hurricane Katrina? Highlight these clusters using the polygon tool in Google Earth. How far are these clusters from the track of Hurricane Katrina? Add this information to the information boxes for the polygons you have created. [Use the measure tool and the track you plotted in Task Two.]
 
 
Research

Task Five

The following table gives the location of some of the impacts of Hurricane Katrina. Use the search bar to find and then placemark these locations. You should add a description to each placemark.
 
Hurricane Katrina's landfall on the Gulf Coast as a strong Category 3 storm with 125 mph (205 km/h) winds.
Buras, Louisiana
Levee Breaks [the 'Where they were found' overlay will help you with the locations]
17th Street Canal, London Avenue Canal and Industrial Canal
The only routes out of the city.
Crescent City Connection and Huey P. Long Bridge
The most severely damaged hotel in the city, with beds reported to be flying out of the windows.
Hyatt Regency New Orleans
Sheltered many people who had not evacuated. Two sections of the roof were compromised and the dome's waterproof membrane had essentially been peeled off. While there were also early reports of fatalities amid mayhem, only six deaths were confirmed there, with four of these originating from natural causes, one from a drug overdose, and one a suicide.
The Superdome
Closed before the storm but did not flood. On August 30, it was reopened to humanitarian and rescue operations. Limited commercial passenger service resumed at the airport on September 13 and regular carrier operations resumed in early October.
Louis Armstrong New Orleans International Airport
An oil rig under construction broke its moorings and floated 1.5 miles northwards before striking a bridge.
