Tectonic hazards

Question 1

What are the factors affecting hazard risk

Answer 1

Population density
Wealth
Deforestation
Climate change

Question 2

How does each one affect hazard risk

Answer 2

Population density- The higher the population density, the bigger the chance of getting affected by natural hazards

WEALTH- people in LICS often live in slums which are prone to flooding and are weak so will collapse. LICS have less money= struggle to cope

DEFORESTATION- Destroying large areas of forest increase risk of flooding, landslides and drought

CLIMATE CHANGE- gives rise to more volatile weather

Question 3

What are the 3 plate margins

Answer 3

Conservative
Destructive
Constructive

Question 4

How do each 3 plate margins act?

Answer 4

CONSERVATIVE- where earthquakes happen, tectonic plates sliding ALONGSIDE each other

DESTRUCTIVE- Where the oceanic plate collided with continental plate, the oceanic plate is forced under the continental plate

CONSTRUCTIVE - tectonic plates move AWAY from each other due to convection current

Question 5

what is the LIC case study for tectonic hazards?

Answer 5

HAITI (2010)

Question 6

What are the primary effects of Haiti

Answer 6

Bottled water provided

Question 9

What are the long term responses of HAITI

Answer 9

after earthquakes, 1 million people still live in temporary shelter
Became dependant on overseas aid

Question 10

what’s the HIC case study for tectonic hazards

Answer 10

Question 11

what are the primary effects of Christchurch

Answer 11

181 people died
Over 50% of the city’s buildings were collapsed

Aid workers from charities helped
300 australian police officers flown in

Question 14

What are the long term responses of CHRISTCHURCH

Answer 14

900 million dollars i’m building insurance claims
Water and sewage restored by August 11

Question 15

why does the effects differ from areas in contrasting wealth

Answer 15

More building collapsed in Haiti becuase many buildings were made from weak materials and are not earthquake proof meaning more buildings collapsed. + a lot of people living in slums so more people died in HAITI than in Christchurch

Cholera broke out in HAITI as they have a lack of money for a purified water supply

CHRISTCHURCH was more prepared so the effects werent as drastic because they have earthquake proof buildings and more money

Question 16

How does the responses differ from areas in contrasting wealths

Answer 16

In Haiti they were forced to wait for help overseas as they couldn’t repair the damages by themselves ( became dependent whereas Christchurch was less dependent)

The government in Haiti could not afford to rebuild homes that quickly which is why 1 million people still live in temporary housing

In Christchurch (2011) water and sewage were restored by August 11 (6 months after earthquake) which was quicker r than Haiti (2010) as they have less resocures and money
