North Korea conducted its fourth nuclear detonation on 6 January 2016 at 10:00:01 UTC+08:30. At the Punggye-ri Nuclear Test Site, approximately 50 kilometres (30 miles) northwest of Kilju City in Kilju County, an underground nuclear test was carried out. The United States Geological Survey reported a 5.1 magnitude earthquake from the location; the China Earthquake Networks Center reported the magnitude as 4.9.
North Korean media made announcements that the regime had successfully tested a hydrogen bomb. However third-party experts—as well as officials and agencies in South Korea—doubted North Korea's claims and contend that the device was more likely to have been a fission bomb such as a boosted fission weapon. Such weapons use hydrogen fusion to produce smaller, lighter warheads suitable for arming a delivery device such as a missile, rather than to attain the destructive power of a true hydrogen bomb.
North Korea (officially the Democratic People's Republic of Korea, or DPRK) had previously conducted three underground nuclear tests in 2006, 2009, and 2013, drawing sanctions from the United Nations Security Council.
The presidents of the United States and South Korea urged North Korea to rejoin the six-party talks in October 2015. The presidents also warned North Korea against a fourth nuclear test.
