COS: Identify ways to prepare for natural disasters in the United States.
Examples: preparing for earthquakes by identifying structural needs of homes before building, constructing houses on stilts in flood-prone areas, buying earthquake and flood insurance, providing hurricane or tornado shelters, establishing evacuation routes
What is a Natural Disaster?
Natural disasters are natural (as opposed to man-made) events that kill people or damage property or the environment. There are many different kinds of natural disasters, some of which are very common.

Tornadoes A tornado is a violent rotating
column of air extending from a thunderstorm to the ground.
The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards.
Damage paths can be in excess of one mile wide to 50 miles long.
In an average year, 1000 tornadoes are reported nationwide.
Effects of Tornadoes
Hurricanes A hurricane is a huge severe
storm over the tropics (oceans).
It can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph.
Hurricanes rotate in a counter-clockwise direction around an "eye" in the Northern Hemisphere and clockwise direction in the Southern Hemisphere.
The center of the storm or "eye" is the calmest part.
Hurricanes produce heavy rain, large waves, high winds and sometimes tornadoes

Effects of Hurricanes
Famous Hurricanes
Hurricane Sandy, 2012

Tsunamis Tsunamis form as a result
of earthquakes, volcanoes or landslides under the ocean
In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15000 people.
Waves grow taller as they reach the coast

Earthquakes Earthquakes are the
shaking, rolling or sudden shock of the earth’s surface.
They are the Earth's natural means of releasing stress.
More than a million earthquakes rattle the world each year.
The West Coast is most at risk of having an earthquake, but earthquakes can happen in the Midwest and along the East Coast.
Earthquakes can be felt over large areas although they usually last less than one minute.
Earthquakes cannot be predicted - although scientists are working on it!
