A 7.2 magnitude earthquake struck off the western coast of Haiti on Saturday, the US Geological Survey said.
A tsunami warning followed for the battered country, still reeling from the assassination of its president last month.
The temblor struck around 8:30 a.m. The USGS recorded a 5.2 magnitude aftershock around 8:49 a.m.
The epicenter of the quake was 7.5 miles northeast Saint-Louis du Sud, according to the survey.
The capital of Port-au-Prince felt the tremor and many rushed into the streets in fear. That city was devastated in 2010 by a massive earthquake that killed over 150,000 people.
