Evaluating Vulnerability in the 2011 Japan Earthquake and the 2010 Haiti Earthquake
The 2010 Haiti earthquake and the 2011 Tohoku earthquake in Japan highlight differences in vulnerability between the two countries. The Haiti earthquake was closer to the capital and more deadly due to high population density, lower GDP, less prepared infrastructure, and greater poverty levels in Haiti compared to Japan. The Japanese were given an earthquake warning while no warning was possible in Haiti.
Introduction to the presentation on earthquakes in Japan and Haiti, focusing on vulnerability.
Overview of the geographical location and tectonic settings of Japan and Haiti.
Details of the 2010 Haitian earthquake (7.0 magnitude, 46,000-318,000 fatalities) vs. 2011 Japanese earthquake (9.0 magnitude, 28,000 dead or missing).
Human Development Index: Haiti (0.49) vs. Japan (0.91), highlighting the disparity in human development.
Economic comparison: GDP per capita for Japan ($34,200) vs. Haiti ($1200), with 77% of Haitians living on less than $2 a day.
Preparedness contrast: Mean years of schooling (Haiti 4.9, Japan 11.6) and earthquake-resistant building designs (0% in Haiti vs. 75% in Japan).
Population density data: Port-au-Prince (24,305 people/sq. km) compared to Japan's national average (337 people/sq. km) and Tohoku (136 people/sq. km).
Demographic statistics: One third of Haiti's population is under 15 years, while 30% of Japan's population is over 65 years.
