Six years after the devastating January 2010, Haiti earthquake, urban development continues at a fast rate in Port-au-Prince and nearby cities along the seismically active Enriquillo fault. Accurate characterization of the regional earthquake hazard in this area is key to inform urban development and construction practices during the long reconstruction phase through which Haiti is currently going. We have recently shown that the seismic hazard map currently in use is significantly incomplete in the metropolitan area of Port-au-Prince and the surrounding Cul-de-Sac basin. This conclusion, based on the discovery of an overlooked component of north- south shortening using space geodetic measurements from the Global Positioning System (GPS), calls for a revision of regional seismic hazard estimates. In addition to its applications in geophysics, GPS — and more generally the Global Navigation Satellite System (GNSS) — has become the technique of choice for surveying and navigation applications operations worldwide. Developing countries such as Haiti are however lagging behind in the use of this technique because of a lack of user training, in spite of a wide range of applications, many relevant to the private sector.
