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 magnitude 8.8 Chile earthquake, which killed 525 people. It was initially thought to be an aftershock of the Chile earthquake, but scientists later established that the earthquakes were unrelated. The epicenter was about 15 miles north of the city of Salta. The quake killed two people, and injured dozens (possibly up to 100 people).
