A quake measuring 6.2 on the Richter scale shook southern Chile Monday, although there were no immediate reports of damage, dpa reported.
The quake's epicentre was 50 kilometres north of Concepcion, Chile's second-largest city, according to the US Geological Survey (USGS). The quake happened close to 30 kilometres underground, the USGS said.
The Chilean Navy stressed that there was no risk of a tsunami to follow the quake.
Concepcion, about 500 kilometres south of Santiago, was among the worst-hit places in the massive 8.8 quake and subsequent tsunami that devastated much of Chile on February 27, 2010.
