Answer 3

China 2008 (8.0) EQ
- social: 69000 dead, 5mn homeless, 7000 schoolrooms destroyed
-economic: $146bn rebuilding
Agri industry destroyed

Haiti 2010 (7.0) EQ

- 90% infrastructure damaged
$14bn damages

Italy 2016 (6.2) EQ
-social: 298 deaths
Econ) $15bn damages, 300 historic building lost

Question 4

Physical factors and context in influencing scale of disaster

Answer 4

Christchurch - liquefaction due to heavy rains - but poor admin gov as built on unstable land
Good political governance through swift establish,ent of CERA (recovery)
But poor and elderly disadvantaged- poor econ governance

Tohoku - 9.0 mag overcame good admin gov ( high quality infrastructure) and good political
Gov (planning like EQ prep day yearly)

Iceland - jokulhaups and lahars caused by meltwater

Question 5

Poor governance

Answer 5

Haiti 2010

Question 6

Hydrometeorological hazards

Answer 6

Philippines - mt pinatubo eruption and typhoon Yunya
Created lahars
Volcanic ash disrupting global flight due to storm winds
Aerosols from volcanic gases and water from storm lead to global cooling

Question 7

Megadisasters

Answer 7

• 2004 Indian Ocean Tsunami
  9.2 magn - destructive plate
  230,000 deaths across 14 countries
  30m wave heights
  Infrastructure destroyed

• Iceland 2010
  Ash clouds disrupted global supply chains as less European flights
• Tohoku tsunami 2011
  Caused a nuclear meltdown disaster - caused power to cut causing nuclear systems to fail
• lead to concerns over nuclear energy - Germany scrapped their nuclear energy programme
