1. INTODUCTION TO NATURAL HAZARDS
PROJECT 04 LESSON 09

2. THE NATURAL HAZARDS THAT COME WITH THE GEOGRAPHY
There are a lot of natural hazards to be aware of when choosing a place to settle.
The zombie outbreak changed a lot of things, but it didn’t stop natural hazards from occurring.
While natural hazards are difficult or even impossible to predict, some hazards are more common in certain areas.

3. FLOODS

4. Floods are one of the most common hazards in the United States, however not all floods are alike.
Some floods develop slowly, while others such a flash floods, can develop in just a few minutes and without visible signs of rain.
Additionally, floods can be local, impacting a neighborhood or community, or very large, affecting entire river basins and multiple states.
Be aware of flood hazards no matter where you live or work, but especially if you are in low-lying areas, near water, behind a levee or downstream from a dam.
Even very small streams, gullies, creeks, culverts, dry streambeds or low-lying ground that appear harmless in dry weather can flood.

6. Tsunamis (pronounced soo-ná-mees), also known as seismic sea waves (mistakenly called “tidal waves”), are a series of enormous waves created by an underwater disturbance such as an earthquake, landslide, volcanic eruption, or meteorite.
A tsunami can move hundreds of miles per hour in the open ocean and smash into land with waves as high as 100 feet or more.

8. A hurricane is a type of tropical cyclone or severe tropical storm that forms in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and in the eastern Pacific Ocean.
A typical cyclone is accompanied by thunderstorms, and in the Northern Hemisphere, a counterclockwise circulation of winds near the earth’s surface.

10. Tornadoes are nature’s most violent storms
Tornadoes are nature’s most violent storms. Spawned from powerful thunderstorms, tornadoes can cause fatalities and devastate a neighborhood in seconds.
A tornado appears as a rotating, funnel-shaped cloud that extends from a thunderstorm to the ground with whirling winds that can reach 300 miles per hour.
Damage paths can be in excess of one mile wide and 50 miles long

11. EARTHQUAKES

12. One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects.
An earthquake is the sudden, rapid shaking of the earth, caused by the breaking and shifting of subterranean rock as it releases strain that has accumulated over a long time.

VOLCANOES

14. A volcano is a mountain that opens downward to a reservoir of molten rock below the surface of the earth.
Unlike most mountains, which are pushed up from below, volcanoes are vents through which molten rock escapes to the earth’s surface.
When pressure from gases within the molten rock becomes too great, an eruption occurs. Eruptions can be quiet or explosive.
There may be lava flows, flattened landscapes, poisonous gases, and flying rock and ash that can sometimes travel hundreds of miles downwind.

15. LANDSLIDES

16. Landslides occur in all U. S
Landslides occur in all U.S. states and territories and can be caused by a variety of factors including earthquakes, storms, volcanic eruptions, fire and by human modification of land.
Landslides can occur quickly, often with little notice and the best way to prepare is to stay informed about changes in and around your home that could signal that a landslide is likely to occur.
