Hurricane Katrina Erodes the
| Title |
Hurricane Katrina Erodes the U.S. Gulf Coast |
| Description |
The graceful curve of the Chandeleur Islands resembles a multi-boned spine connecting the Mississippi Gulf coast to the delta of the Mississippi River in Louisiana. Like all barrier islands, the Chandeleur Islands form a thin protective wall between the open sea and the mainland, in this case Louisiana's St. Bernard Parish. The islands absorb the strongest waves, sheltering the mainland during large storms. It is no surprise, then, that barrier islands along the U.S. Gulf Coast changed dramatically in the wake of Hurricane Katrina, and no change is as dramatic as that seen in the Chandeleur Islands. Hurricane Katrina's strong winds, storm surge, and battering waves scoured the islands, leaving them reduced or gone altogether. These images of the islands were taken by the Landsat 5 satellite. The top image, taken on September 16, 2005, shows the Mississippi and Alabama coast line, including the line of islands that bore the brunt of Katrina's fury. The lower images show the northern section of the Chandeleur Islands at full resolution. In the 11 months that passed between October 15, 2004, when the right image was taken, and September 16, 2005, when the left image was taken, the islands have wasted away. Barrier islands like the Chandeleur Islands are constantly building, eroding, and shifting under the normal actions of wind and waves. A powerful storm like Katrina can produce changes that otherwise may have taken many years, and most of the change seen here is probably a result of Katrina. Hurricane Dennis also gave the islands a glancing blow on July 10, 2005, and may be responsible for some of the change. The other barrier islands shown in the top image were also scoured by Katrina. The large images show that the Ship Islands [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13130 ] are now significantly smaller than they were in 2004, and Dauphin Island [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13132 ] has been cut in two.

Hurricane Katrina Floods the

Hurricane Katrina Floods the Southeastern United States |
| Description |
The floods that buried up to 80 percent of New Orleans had noticeably subsided by September 15, 2005, when the top image was taken by the Landsat 7 satellite. In the two and a half weeks that had passed since Hurricane Katrina flooded the city, pumps had been working nonstop to return the water to Lake Pontchartrain. As portable pumps were brought in to supplement the permanent pumps already hard at work, as much as 380 cubic meters (380,975 liters or 11,300 cubic inches) of water were being pumped out of New Orleans every second, according to the U.S. Army Corps of Engineers [ http://www.hq.usace.army.mil/cepa/katrina/pumps/pumps.html ]. The progress in draining the city is evident when the September 15 image is compared with an image taken one week earlier. In the lower image, taken by the Landsat 5 satellite on September 7, black flood water covers much of the city. By September 15, the dark flood water had all but disappeared, lingering only in a few sections of the city. The September 7 image does not show the full extent of the flooding. Taken more than a week after the hurricane struck New Orleans, the image shows a flooded city that had already started to drain. In a similar (but cloudy) image taken on August 30 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13094 ], the flood water in St. Bernard Parish, image right, extends almost to the Mississippi River.
