Over a week after a devastating 7.0 magnitude earthquake struck Haiti, another 6.1 magnitude rattled the island on Wednesday morning around 6 a.m local time.
The aftershock was about 6.2 miles deep, with an epicenter located about 35 miles from the capital Port-au-Prince.
The US Geological Survey (USGS) said the latest earthquake struck about 35 miles southwest of the capital.
Similar to the earlier 7.0 earthquake that killed over 200,000 in the Port-au-Prince area, today's earthquake was relatively shallow, occurring about 6.2 miles below the surface.
The extent of the damage caused by the aftershock is not yet clear, but it appears to be minimal according to Agence France Press.
Bruce Pressgrave, a geophysicist with the U.S. Geological Survey, says the aftershocks are a sign the land is adjusting to the new reality of the rock layers.
Pressgrave said the revival of strong quake activity in an area dormant for 200 years renews researchers' concerns about whether major seismic activity in one area of plate boundaries could trigger quakes in other parts of the world.
