NATURAL DISASTERSWorkshop 2

TYPES OF NATURALS DISASTERS

• Tornado• Hurricane• Mudslide/landslide• Ice storm• Snow storm• Drought• Flood

• Typhoon• Wild fire• Sand storm• Lightning• Volcano• Earthquake • Tsunami

TORNADOES• Also called - twisters or cyclones • Damage paths can be 1 mile wide to

50.• Funnel clouds usually last less than

10 minutes, and many only last several seconds.

• The result of a supercell thunderstorm, due to the way cold air & warm air combine. The warm air twists into a spiral & forms the funnel that we all associate with a tornado.

• Range from F0 to F5• Wind Speed: 261 - 318 mph • Cars are thrown through the air • Entire houses are completely

destroyed after being ripped from the foundation and sent tumbling into the distance

Earthquakes • Usually triggered by movement of

the earth's plates – Earth is made up of 20 constantly moving plates.

• As the plates shift, tension is created, and it can cause the crust to break. When a break occurs, the stress is released as energy that moves through the Earth in the form of waves. These waves are earthquakes.

• The National Earthquake Information Center records an average of 20,000/ year (about 50 a day) around the world.

• There are millions that occur every year that are too weak to be recorded.

• Almost 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire"; a region that encircles the Pacific Ocean and is home to 452 volcanoes

Typhoons• Typhoons, cyclones and hurricanes

are all rotating tropical storm systems that starts at sea. The name depends on where it starts.

• The eye of a typhoon or hurricane can be anywhere between 2mi across right up to 200mi.

• A typhoon becomes a super-typhoon once surface winds of over 150mph have been sustained for more than a minute.

• Due to its location in the tropics, the Philippines is one of the most prone countries to typhoons, as well as other natural disasters like earthquakes.

Tsunami• Ocean waves caused by an

underwater earthquake, landslide, or volcanic eruption

• Can reach heights of over 100 feet• 80% of tsunamis happen within

the Pacific Ocean• First wave of is usually not the

strongest, successive waves get bigger and stronger.

• Can travel at speeds of about 500 miles per hour, almost as fast as a jet plane.

• The states in the U.S. at greatest risk for tsunamis are Hawaii, Alaska, Washington, Oregon, and California.

• Hawaii is the U.S. state at greatest risk for a tsunami – they get about one per year and a damaging one every seven years.

• Biggest in Hawaii: 1946, where the coast of Hilo Island was hit with 30 foot waves at 500 miles per hour. 170 people died as a result.

• In 2004, the Indian Ocean tsunami had killer waves that slammed into the coastline of 11 countries, damaging countries from east Africa to Thailand. The final death toll was 283,000.

• On March 11, 2011, a 9.0 earthquake and tsunami struck Japan. The death toll was 16,000, with 6,000, and destroyed or damaged countless buildings.

Ice Storm Wild fires

Drought • Farmers lose money • Ranchers may have to spend more

money on feed and water for their animals.

• Greater risk of wild fires• No Water transportation• People might have to pay more for food. • Losses or destruction of fish and wildlife

habitat• Lack of food and drinking water for wild

animals• Increase in disease in wild animals,

because of reduced food and water supplies

• Lower water levels in reservoirs, lakes, and ponds

• Loss of wetlands• Wind and water erosion of soils• Poor soil quality

Sand storms AKA Dust storms

• Caused by strong winds blowing over loose soil or sand, causing to be greatly reduced.

• Deserts are the most common locations for sandstorms
