A magnitude 6.8 earthquake shook central Chile Saturday with no damage or injuries reported so far. The tremor comes just two months after another quake hit the same area.

Buildings reportedly swayed in capital city of Santiago, but no tsunami alert has been issued. The U.S. Geological Survey said the earthquake struck 30 miles southwest of Ovalle, a city nearly 185 miles northwest of Santiago, at a depth of 22 miles.

"The situation in the region of the epicenter is now in a state of normality," Ricardo Toro, head of emergency services, said at a press conference, according to the Associated Press, adding that the latest quake was part of a string aftershocks that rattled the country from an 8.3 earthquake, which hit off the coast of Chile on Sept. 16.

At least 11 people were killed in September’s earthquake that triggered tsunami warnings and forced evacuation of over 1 million people from the coastal area.

Chile ranks among the most vulnerable nations to earthquakes in the world and has seen devastating quakes in its past. A devastating earthquake in 2010 killed 525 people in the south-central part of the country that cost an estimated $30 billion in damages.
