Test chronology | |
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;[7] the China Earthquake Networks Center reported the magnitude as 4.9.
North Korean media announced that the country had successfully tested a hydrogen bomb in "self-defence against US".[8] However, third-party experts as well as officials and agencies in South Korea questioned 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.[9]
