Reasons for high death rate in Haiti

  1. 1. Why did so many die in the Haiti Earthquake?
  2. 2. Physical <ul><li>High magnitude event (7.0 on Richter scale) </li></ul><ul><li>Epicentre close to largest city (just 16 kms to S W) which housed almost third of Haiti’s population. </li></ul><ul><li>Focus was very shallow - only 8 kms below surface. This would lead to greater impact at surface </li></ul><ul><li>Time - 1653 local time on a Tuesday - people at work or on way home from work, so down-town Port-au-Prince at high risk. </li></ul><ul><li>Dozens of aftershocks - some as high as 5.9 and 5.5 - which brought down the weakened buildings. </li></ul><ul><li>200 years of stored energy (refer theory of strike-fault tectonics) </li></ul><ul><li>Sitting on a major strike-slip fault (Enriquillo fault) </li></ul><ul><li>Some unstable ground leading to landslides. </li></ul><ul><li>Hurricanes (4 in 2008) weakened those buildings not destroyed and led to 800,000 having to live in cheap housing which would be less earthquake resistant. </li></ul>
  3. 3. Economic <ul><li>Poverty - 66% earn less than £1 day so many can only live in shoddily built homes. </li></ul><ul><li>Poorest country in western hemisphere by far so very little to invest in earthquake proof buildings </li></ul><ul><li>60% buildings badly built and so far from being earthquake proof. </li></ul><ul><li>Airport too small to cope with aid and relief from outside agencies which hampered rescue </li></ul><ul><li>Hurricanes (4 in 2008) weakened those buildings not destroyed and led to 800,000 having to live in cheap housing which would be less earthquake resistant. </li></ul><ul><li>Blocked roads and phone lines down hampered rescue so leading to more deaths </li></ul>
  4. 4. Socio-political <ul><li>Having suffered with disasters previously (flooding 2004, mudslides 2004, 4 hurricanes 2008) perceived they were due for a disaster free time! Therefore ill-prepared. </li></ul><ul><li>No major earthquake for 200 years and therefore far removed from consciousness and so not prepared. </li></ul><ul><li>Political instability - corrupt government and little investment in improving buildings and roads. </li></ul><ul><li>Many decision-makers & aid workers (permanently in Haiti) killed - so chaotic initial response </li></ul><ul><li>Blocked roads and phone lines down hampered rescue so leading to more deaths </li></ul><ul><li>Hurricane damage in Genaives led to migration to Port-au-Prince so causing high density living conditions which raised the chance of more deaths. </li></ul>
  5. 5. <ul><li>The reasons for the huge number of deaths is very complex and a combination of physical, economic and socio-political factors as shown in the previous slides </li></ul>
