The 2010 Salta earthquake occurred on February 27 at 12:45:36 local time in Salta Province, Argentina and had a magnitude of 6.3. It occurred less than 12 hours after the far larger 2010 Chile earthquake, which killed over 500 people. Initially thought to be an aftershock of the Chile earthquake, scientists later established that the earthquakes were unrelated. It took place just to the north of the city of Salta.
