2. Introduction
Natural Disasters are naturally occurring events
which can directly or indirectly cause severe threats
to a publics well-being. They are from atmospheric,
geological and hydrological origins that can cause
human loss, property damage and social
environment disruption. Some examples are:-

Hurricanes
Tsunamis
Volcanic eruptions
Mudslides / Landslides
Floods
Earthquakes
Tornadoes
Storms

3. HURRICANE
Hurricanes occur because their source of energy is water vapor, which is
evaporated from the ocean surface. It releases the latent heat of
condensation when it condenses to form clouds and rain, warming the
surrounding air. The heat was absorbed by the water vapor when it was
evaporated from the warm ocean surface, so the warm ocean cools
down; a hurricane is like the Earth's air condition that helps to cool the
Earth.

Hurricane Katrina, 2005

12. On August 28th, 2005, it was an early
Monday morning when Hurricane Katrina hit
the southern coast of the United States.
More than 1,800 people lost their lives and
more than more than $81 billion dollars in
damages occurred.
Hurricane Katrina is one of the five
DEADLIEAST natural disaster, in the
history of the United States.

13. Is Known for
• Its multicultural and multilingual heritage
• Cuisine
• Architecture
• Music (particularly as the birthplace of jazz)
• Its annual celebrations and festivals, particularly Mardi Gras.
• The city is often referred to as the "most unique" city in
America
New Orleans

14. Hurricane Katrina formed over the Bahamas on August 23, 2005 and
crossed southern Florida as a moderate Category 1 hurricane, causing
some deaths and flooding there before strengthening rapidly in the Gulf
of Mexico The storm weakened before making its second landfall as a
Category 3 storm on the morning of Monday, August 29 in southeast
Louisiana.
The storm rapidly intensified after entering the Gulf, growing from a
Category 3 hurricane to a Category 5 hurricane in just nine hours. This
rapid growth was due to the storm's movement over the "unusually
warm" waters of the Loop current, which increased wind speeds. On
Saturday, August 27, the storm reached Category 3 intensity on the
Saffir-Simpson Hurricane Scale, becoming the third MAJOR hurricane of
the season.

16. Hurricane Katrina impacted New Orleans socially, economically,
politically and environmentally.
Impacts

17. Social impacts
It left people homeless, stranded and unemployed. The
effects on the people were devastating. Food and fresh
water was so scarce that people were forced to the
streets, which resulted in violence, racial aggression, theft
and murder. Families were separated and the city of New
Orleans was completely destroyed.

18. An excess of $200 billion in damages occurred, making
Katrina one of the most economically costly hurricanes
ever to hit the United States. The storm interrupted oil
production, importation, and refining in the Gulf area,
thus having a major effect on fuel prices. The fuel prices
increased causing the economy to slow.
Economic impacts

19. In addition to the deaths, shattered lives, and billions of
dollars in property damage that Hurricane Katrina caused,
the hurricane left a long-lasting legacy of environmental
damage and serious threats to public health.
Environmental impacts

20. The political impacts of Hurricane Katrina have been largely
caused by the negligence and lack of leadership in the
relief effort. Criticism was prompted largely by televised
images of New Orleans residents who remained stranded
without water, food or shelter; and the deaths of several
citizens of thirst, exhaustion, and violence days after the
storm itself had passed.
Political impacts

21. The effects of Hurricane Katrina in New Orleans were
long-lasting. Reconstruction of New Orleans has been
ongoing ever since the hurricane struck the city. By
Monday, September 5, 2005 power began to be restored to
buildings in the central business district of New Orleans on
a priority basis. Relief agencies have helped many
returnees. The Red Cross made a belated significant entry
into the city in mid-September, and by the start of October
had a number of relief centers set up around the city .
