Where did the Haitian earthquake hit the hardest?

The US Geological Survey provide a contour map of earthquake intensity for the earthquake that occurred on the 12th of January, 2010. This indicates that the highest intensity (perceived shaking) with a level of 10 (X) on the Modified Mercalli Intensity Scale occurred in Grand Goave (population 5000). The Haitian capital Port-au-Prince suffered an intensity 9 event.

The scale indicates that at this intensity structures will suffer heavy to very heavy damage.
