S. Korea says artificial quake occurs in N. Korea
SEOUL, Jan. 6 (Yonhap) -- An earthquake occurred in North Korea near the country's nuclear test site, South Korean officials said Wednesday, a strong indication that the communist country may have carried out a nuclear test.
The Meteorological Administration said the 4.2-magnitude quake occurred in an area, some 49 kilometers north of Kilju, home to the country's Punggye-ri nuclear test site.
Cheong Wa Dae, South Korea's presidential office, plans to hold a session of the National Security Council over the issue.
The U.S. Geological Survey put the preliminary magnitude at 5.1. It's not clear why there are varying magnitudes.
North Korea has hinted that it may conduct a nuclear test in response to what it claims is a hostile policy by the United States and its allies toward the country.
North Korea conducted nuclear tests in 2006, 2009 and 2013, drawing international condemnation and U.N. sanctions.
