1. Lessons from the Haiti Earthquake Takaaki Sato Kazuki Tanuma Soichiro Endo NGUYEN VIET NGA B3 Students Department of Civil and Environmental Engineering Tokyo Institute of Technology

2. Outline Why did earthquake happen? Main causes make earthquake’s damage more than twice as lethal as any previous magnitude 7.0 event. Conclusions

3. Haiti earthquake in detail The absence of surface rupture means that elastic energy is still stored. Port-an-Prince In 1751, a violent earthquake to the east occurred. In 1770, reconstructed city was again demolished. Port-an-Prince In 1751, a violent earthquake to the east occurred. In 1770, reconstructed city was again demolished. More shocks soon? → have released all the elastic energy?

4. Why the damage grow worse? ⅰ ) The uneven application of appropriate building codes About 80% of all schools collapsed in the Port-au-Prince area, and a similar percentage in the 2005 Kashmir earthquake. If buildings are not made earthquake resistant, the toll is likely to continue to rise as cities grow in population. Global increase in population would anticipate. Haiti has been same situation in earthquake. ⅱ） Population increasing : a collapsed buillding : A Haitian city after the earthquake

5. Conclusions Training contractors and labourers in sound construction methods. Introduce appropriate building codes. →Ensure that people do not construct buildings designed to kill their occupants It is time for civil engineers to flourish!!
