The strong 2010 Haiti earthquake had its epicentre near Port-au-Prince, Haiti’s capital. It killed about 230,000 people, injured another 300,000, and made another 1,000,000 homeless a huge impact on a country of 10 million. The earthquake caused an estimated $10 billion worth of damage, more than Haiti’s annual GDP, a huge impact on a small, poor country.

The Big Picture photoblog has a great collection of photos from a year after the quake:

New York Times has a collection of aerial photos that show Haiti before the quake, immediately after, and now.  They also have the stories of six Haitians in the year after the quake.

NPR has a collection of stories on the post-quake recovery.

Michael K. Lindell writes in Nature Geoscience on the need for earthquake resilient buildings. He writes:

Usually, the poorest suffer the most in disasters that hit developing countries, but this may not have been so in Haiti. The lowest quality housing experienced less damage than many higher quality structures. Specifically, shanty housing made of mixed wood and corrugated metal fared well, as did concrete masonry unit structures made of concrete blocks and corrugated metal roofs. These inexpensive shacks probably had a very low incidence of failure because they are such light structures. At the other extreme, the most expensive seismically designed structures also seem to have performed well, but for quite different reasons. Although they were heavier, they had designs that avoided well-known problems, and the materials used in building were of adequate quality and quantity. It seems to have been the moderately expensive structures, built with concrete columns and slabs, that were reinforced, but concrete block walls that were not. Such structures frequently experienced severe damage or collapse because their builders cut costs with inadequate designs, materials and construction methods.

The relationship between building cost and seismic safety thus seems to be not just non-linear, but non-monotonic. That is, people can spend their way into hazard vulnerability, not just out of it. To avoid this problem, three main requirements must be met. First, earthquake risk maps are needed to identify the areas where seismic-resistant construction is required. Second, building codes must then be adopted, implemented and enforced. Finally, insurance is required to fund rebuilding after an earthquake in which building codes have saved lives but not buildings.

…

Today, mitigation of earthquake hazards is not held back primarily by a lack of engineering solutions: architects had access to manuals for seismic-resistant design for nearly 20 years at the time of the Haiti earthquake. But substantial further research is needed to examine how people can be convinced to make use of existing options for achieving physical and financial safety — especially in areas, such as the Central United States New Madrid seismic zone, that have earthquake recurrence intervals of hundreds of years. Implementing risk-management strategies for coping with such low-probability, high-consequence events will require innovative public/private partnerships.

Ultimately, even the poorest countries must regard building codes as necessities, not luxuries. Moreover, even relatively wealthy countries need to develop more effective strategies for managing seismic risks. This will require collaboration among earth scientists, social scientists, earthquake engineers and urban planners.
