The 6.1 magnitude shaking produced only a little additional damage but instilled even more fear into the desperate surviving population.
Wednesday morning’s aftershock at daybreak sent shrieking Haitians running away from buildings and walls in the shattered city fearing a repeat of the magnitude 7 earthquake that killed tens of thousands of people eight days ago.
The U.S. Geological Survey said the aftershock was centered 30 miles west-southwest of Port-au-Prince at a depth of 6 miles. The epicenter was about twice as far to the west of the capital as the initial quake.
Wednesday's shaking was the 14th aftershock stronger than magnitude 4 to hit the disaster zone during the previous week.
Each seismic echo sent terrified residents and rescue workers fleeing buildings in fear of further collapses.
