A magnitude-3.5 quake jolted South Korea's southwest on Tuesday, officials said, but there were no immediate reports of damage.

The predawn quake hit Iksan, some 250 kilometers south of Seoul, and was also felt in Seoul and the second-largest city of Busan, according to the Gwangju Regional Meteorological Administration.

"The house windows shook hard for seven to 10 seconds and I heard banging sounds," a 58-year-old resident in Iksan told Yonhap News Agency, requesting not to be named.

It was the second-strongest quake to hit the Korean Peninsula in 2015 following the 3.7-magnitude one which struck near the southern resort island of Jeju in August, according to the meteorological administration. (Yonhap)
