An earthquake struck northern Chile early Tuesday, the US Geological Survey said.
The tremor hit 70 kilometers (43 miles) east of the coastal city of Arica, which is near the border with Peru, the US agency said.
The quake struck at a depth of 82kilometers, it added. Strong aftershocks rippled through Chile after a magnitude 8.3 earthquake that killed at least eight people and slammed powerful waves into coastal towns, forcing more than a million people from their homes.
The government ordered evacuations from coastal areas after the powerful quake hit, seeking to avoid a repeat of a quake disaster in 2010 when authorities were slow to warn of a tsunami that killed hundreds.
