Haiti Earthquake: Ten Years On

This week marks the tenth anniversary of the devastating earthquake in Haiti. The magnitude 7.0 event ruptured a thrust fault associated with the Enriquillo-Plantain Garden fault system 25 kilometers (16 miles) west of the capital city Port-au-Prince. This fault system runs along the length of the Tiburon Peninsula and is no stranger to earthquakes, with major events impacting Haiti in both 1751 and 1770. This large time gap since the last major events meant that there was little to no societal memory or preparedness for earthquakes in the region, making the 2010 event particularly devastating.

In the 2010 event, the strong ground shaking lasted 30 seconds and caused extensive collapse of masonry and concrete structures due to both poor design and construction practices, and poor construction material quality. An estimate for the resulting death toll is a staggering 150,000 people.

The scale of the damage and the number of people killed impacted all aspects of life for the remaining inhabitants of Port-au-Prince and the surrounding regions. Vital infrastructure including hospitals, communication systems and transportation facilities (e.g., the airport and port in Port-au-Prince) was severely damaged or destroyed, hampering disaster response. With 250,000 homes severely damaged, more than one million people needed to be housed and fed.
