Hazardous Environment - 3.2 (Reasons for Living in High-Risk Areas; Case Studies)

-

Reasons for Living in High-Risk Areas

Volcanic Areas

  • Volcanic soils are very fertile
  • People don't think it's possible for the volcanoes to erupt
  • Some volcanoes are popular tourist destination
  • Tradition and religion
  • A lot of poor people can't afford to move
  • Volcanoes provide geothermal energy
  • Lots of money can be made from minerals
  • Landscapes can be very pretty

Earthquakes Areas

  • Some earthquake prone areas like Turkey and Iceland are popular tourist destination
  • People in MICs feel safe in earthquake zones because of quake proof infrastructure
  • Some places (like California) are beautiful
  • People don't think they'll be hurt
  • Lack of education
  • Some countries are more vulnerable than others to the impacts of natural hazards because they're poorer, their location makes them have disasters all the time or they're not prepared.

2005 Hurricane Katrina

Long-Term Effects

  • 80% of New Orleans was flooded for weeks
  • 30 oil platforms were destroyed, costing the US billions
  • Racial tensions were exposed as many of the victims were African-American
  • Repairs and reconstruction cost over $150 billion
  • Thousands of jobs disappeared due to the area being destroyed
  • 26 million litres of oil were spilled

Short-Term Effects

  • People took protection in the Superdome stadium
  • 1,833 people lost their lives
  • There was a lot of looting of abandoned places
  • Emergency response was slow
  • Flood protection was destroyed

2010 Haiti Earthquake

Long-Term Effects

  • Government buildings were destroyed and the police force collapsed
  • By November (the earthquake was in January) there were outbreaks of cholera
  • Haitian tourist industry declined
  • There was so much damage that aid and reconstruction was prevented from being done effectively

Short-Term Effects

  • 220,000 people were killed
  • 200,000 homes were damaged in Port-au-Prince
  • 1.3 million Haitians were displaced
  • Eight healthcare centers were damaged/collapsed

2010 Indonesia Eruption - Mount Merapi

Long-Term Effects

  • Emergency shelters couldn't be closer than 15 km from the volcano because of ash and dust
  • Nearly 300,000 people had to leave their homes
  • Flights in Australia were grounded because of ash and dust
  • Damage to crops caused food shortages

Short-Term Effects

  • Volcanic bombs landed over 11 km away
  • Pyroclastic flows spreading 3 km down
  • 350 people died
  • Sulphur dioxide was blown all the way to Australia
  • Ash plumes went up to 5 km and landed up to 30 km away

Hazardous Environments - 3.1 (Tropical Cyclones, Hurricanes and Typhoons; Earthquakes and Volcanoes)

Tropical Cyclones, Hurricanes and Typhoons What is the difference between the three? Cyclones are formed in the Indian Ocean, hurricanes in the Middle Atlantic and typhoons in the Pacific Ocean.  Cause:  Start when high temperatures cause air to rise from the surface of the sea. The rising air causes local thunderstorms, and sometimes these storms come together and create a strong flow of warm, rapidly rising air, creating an area of increasingly low pressure. (Applies to hurricanes + typhoons as well) Ocean water must be 26 degrees celsius and at least 50 metres deep to form a cyclone/hurricane/typhoon. Characteristics Have very low pressure Often 600-900 km across Bring torrential rain, thunder, lightning, and strong winds Can cause widespread damage On average last for 10 days, but can last for up to 4 weeks Have to form on large bodies of water Don't remain where formed. They follow the direction of prevailing winds and ocean currents The

River Environments - 1.3 (Case Studies)

-
Case Study: The River Tay (UK) Use of land and river: Delta on the Tay is used as a gold course. Flood plain transformed from farming to settlements; the land is flat but benefits need to be weighed against the risk of flooding. Port still has ships sailing into it. Fertile soil is ideal for arable and mixed farming. Rivers provide a transport route for inaccessible areas Water wheels used to power surrounding industries Water wheels are a tourist attraction Sheep farming Forest of pine trees River Tummel (one of Tay's tributaries) provides water and hydroelectricity Water Shortages ✩ Area of deficit - Location where rain doesn't fall enough to provide enough water on a permanent basis ✩ Area of surplus - Areas that have more water than needed ✩ Water stress - Occurs when the amount of water available doesn't meet the required amount How can water demand be met in a more sustainable way? Increase awareness More efficient housing design Taki

Berlin Blockade

-
Divided Berlin After WW2, Germany and Berlin were divided into four zones. All the zones were in economic chaos. Stalin feared a recovering Germany, so wanted to cripple it. In 1946, France, Britain and the USA combined their zones, and in 1948 they reformed the currency. The Blockade Stalin felt that the USA's handling of Germany was provocative. In June 1948, Stalin blocked off all supply lines, cutting off 2 million people in West Berlin. If US tanks did try to ram the blocks imposed, it would be seen as an act of war. Truman wanted to show that he was serious about his policy of containment. The Berlin Airlift The only way into Berlin was air. In June 1948, the Allies decided to airlift supplies to West Berlin. For the next ten months, planes were bringing in everything West Berliners needed with the planes coming in 3 times a minute. By May 1949, it was clear that the Allies weren't going to give up so Stalin reopened the communications. Conse
