TECTONICS CASE STUDIES Flashcards
outline the social impacts of the tsunami and earthquake in indian ocean 2004
14 countries affected
primary impacts :
nearly 300,000 deaths
4 million fell into poverty or deeper poverty
secondary impacts :
speaking of malaria and cholera
lack of safe water and sanitation - many deaths of young people due to waterborne diseases

damage estimated at $9.4 billion
lost businesses - 60% of sri lanka’s fishing fleet destroyed - their main industry
loss of earnings from tourism - foreign visitors to phuket dropped 80% in 2005
outline the environmental impacts of the tsunami and earthquake in indian ocean 2004
farm land ruined by salt water
8 million litres of oil escaped in indonesia
mangrove forests along the coast were destroyed
what factors contributed to the level of disaster in the tsunami and earthquake in indian ocean 2004
magnitude = 9.0
densely populated coastal communities close to epicentre
tsunamis not common indian ocean , no warning system , sri lanka and indonesia unaware of the dangers - unprepared to cope
many countries were LICs so could not afford prep or prevention - relief hes holy in foreign aid
what two earthquake / tsunami studies to compare
japan 2011 ans indian ocean 2004
outline the social impacts of the earthquake and tsunami in japan 2011
20,000 death toll
500,000 left homeless
80,000 people evacuated due to fukushima explosion
65% of victims over age of 60
outline the economic impacts of the earthquake and tsunami in japan 2011
$360 billion in damage
50 nuclear reactors were closed , japan had to import oil causing trade deficits
tourism decline
fukushima power plant exploded
outline the environmental impacts of the earthquake and tsunami in japan 2011
nearly 4,400 times more radiation than maximum safety levels
high levels of radiation released into air and water
surge of water carrier estimated 5 million tons of debris to sea
what factors contributed to the level of disaster in the 2011 japan earthquake and tsunami
magnitude = 9.0
70% of japan is mountainous so most infrastructure is in low lying area
prime ministers accepted government are too complacent and has to believe in technological infallibility
tsunami sea wall was outdated and sunk by 1m due to the earthquake so wave height exceeded wall
how does sichuan’s earthquake death toll compare to japan
sichuan 87,5000 magnitude 7.9
japan , 20,000. magnitude 9.0
what are the two comparing volcanic eruption studies
my nyriagongo , democratic rep public of congo 2002 and eyjafjakolul in iceland 2010
outline the social impacts of volcanic eruption in democratic replublid of congo
12,500 homes were destroyed
45 dead in first 24 hours
14 nearby villages destroyed by lava flow
cholera spread due to lack of sanitation in refugee camps - death toll adds to 147
outline the economic impacts of volcanic eruption in democratic replublid of congo
350,000 people dependant on aid one month after eruption
2/4 hospitals , 3/11 health centres and 80/150 pharmacies were buried under two meteres of lava
outline the environmental impacts of volcanic eruption in democratic replublid of congo
poisonous gases causes acid rain affecting farmland and cattle
lake kivu polluted by sulphurous gases this wws oroevoously used as a main source of drinking water
factors contributing fo level of disaster in volcanic eruption my nyriagongo in DRoC
volcano is located 15km from goma - highly populated area exposed to the hazard
composite volcano - lava can reach speeds of up to 97km/h and is highly explosive
low development , 69% of population lives in poverty in 2004
political unrest - the five station seismic network wws vandalised during the civil war
