urricane Katrina lashed the south and the center of the United States
in August 2005. The force of the wind razed thousands of houses,
buildings, oil installations, highways, and bridges, leaving a vast areaof the country without communication and some heavily populated areas
without provisions. It resulted in extensive material damage and thousands
of deaths in Florida, the Bahamas, Louisiana, and Mississippi. Satellite images
reveal the scope of the disaster, considered one of the most devastating in
the history of the country.
