This would have been an aftershock from the main earthquake that occurred on the 27th of February. The aftershocks occur because there are still stress concentrations in the crust around the fault even after the main quake and these concentrations of stress (and their resultant strain) can still cause fault ruptures leading to earthquakes.

Where can you find geological information on the Chilean earthquake?
There have been a number of "famous" or perhaps "infamous" Chilean earthquakes, including the 1960 Valdivia Earthquake, which with a magnitude of 9.5 was the largest ever recorded by seismometer. Another was the earthquake that occured in February 2010 shortly after the devestating Haitian earthquake of January 2010. For more information, please see the related question and links.
What was the biggest earthquake in 2010?
The Chile Earthquake in February was the biggest earthquake reported in 2010.
What is the difference between the Haitian earthquake and the Chilean earthquake?
The two earthquakes occurred due to differing types of fault movement (thrust faulting in the Chilean quake vs strike slip faulting in the Haitian quake) and at two differing types of plate boundaries. In the case of the Chilean earthquake, this was at a convergent boundary where the Nazca oceanic plate is being subducted under the continental South American plate as opposed to the Haitian earthquake which occurred at a transform boundary between the Caribbean and North American plates which are both moving east but at differing speeds. The Haitian earthquake was also of lower magnitude (magnitude 7.0) than the Chilean earthquake (magnitude 8.8) however it caused more damage and led to a much larger number of injuries and fatalities due to the poor construction techniques used in Haiti.
