A largest aftershock of last week’s devastating earthquake in Haiti struck this morning 35 miles west-south-west of the nation’s capital, Port-au-Prince.

The 6.1 magnitude temblor was located 6.2 miles below the surface, according to the U.S. Geological survey.

The quake shook rubble from damaged buildings and sent people screaming into the streets, according to an Associated Press report.

The extent of additional damage or injuries was not immediately clear, according to the report.

In the capital’s downtown area, near the national palace there did not appear to be any new damage, the New York Times reported.
