A 2.8 magnitude earthquake took place near North Korea's northeastern nuclear test site Wednesday in an apparent aftermath of the communist country's previous nuclear test, South Korea's weather agency said.

The quake occurred about 11 kilometers east of the Punggye-ri nuclear test site in Kilju, North Hamgyong Province, at 7:20 a.m., the Korea Meteorological Administration (KMA) said.

The North carried out its sixth and most powerful nuclear test in the Punggye-ri site in September 2017, causing several induced quakes thereafter.

"The (Wednesday) quake is presumed to have naturally occurred due to the influence of the North's sixth nuclear test," Woo Nam-cheol, a KMA geological analyst, said. (Yonhap)
