September 2016 North Korean nuclear test

The government of North Korea conducted a nuclear detonation on 9 September 2016, the fifth since 2006, at the Punggye-ri Nuclear Test Site, approximately northwest of Kilju City in Kilju County.
Background.
North Korea's previous nuclear test was conducted 8 months earlier in January 2016 and drew sharp international condemnations. Despite calls from China and Russia to return to the six-party talks, North Korea maintained its nuclear and missile ambitions:
The nuclear test was conducted on 9 September 2016, which is the 68th anniversary of the founding of [[North Korea]].
Yield estimates.
According to [[Government of South Korea|South Korean]] and Japanese estimates, the [[Nuclear weapon yield|nuclear yield]] was equivalent to about 10 [[TNT equivalent|kilotons of TNT]] (10 kt), generating about a 5.3 [[Moment magnitude scale|magnitude]] seismic shock. This would make the explosion the largest North Korean nuclear test.
Jeffrey Lewis of the [[California]]-based [[Middlebury Institute of International Studies at Monterey|Middlebury Institute of International Studies]] told Reuters that the blast is estimated to be at least . The article has since been republished by some international media outlets. Such a yield would make the blast more powerful than that of the [[Little Boy]] atomic bomb [[Atomic bombings of Hiroshima and Nagasaki#Hiroshima|dropped on Hiroshima]] in 1945.
The German [[Bundesanstalt für Geowissenschaften und Rohstoffe|Federal Institute for Geosciences and Natural Resources]] has initially estimated the yield as 25 kt.
The [[Japan Self-Defense Forces|Japanese military]] dispatched two Kawasaki [[Kawasaki T-4|T-4]] aircraft fitted with special containers to measure airborne radioactivity.
On 10 September 2016, the academics from [[University of Science and Technology of China]] have released their findings based on seismic results and concluded that the Nuclear Test Location is at 41°17'54.60"N, 129°4'40.80"E on 00:30:01.366 UTC which is only a few hundred meters apart from the previous 3 tests ([[2009 North Korean nuclear test|2009]], [[2013 North Korean nuclear test|2013]] and [[January 2016 North Korean nuclear test|January 2016]]) with the estimated yield at 17.8 ±5.9 kt (An estimated yield between 11.9 kt to 23.7kt).
In August 2017, [[Siegfried S. Hecker]], former director of the [[Los Alamos National Laboratory]], estimated yield as between 15 and 25 kilotons.
North Korean response.
The North Korea [[Korean Central News Agency|state media]] did not immediately announce the test, instead showing archive footage of the country's founder, [[Kim Il-sung]], as well as of his son and former leader [[Kim Jong-il]].
By 13:50 [[Time in North Korea|Pyongyang Standard Time]], state media [[Korean Central News Agency|KCNA]] confirmed that this was the fifth nuclear test and that the "warhead can be mounted to a missile".
International response.
The test, conducted in defiance of the [[international community]], prompted wide international condemnation.
The [[UN Security Council]] condemned the test and said it would formulate a new resolution, with the US, Britain and France pressing for new sanctions. [[United States Secretary of Defense|US Secretary of Defense]] [[Ash Carter]] stated in a press conference that "China has and shares an important responsibility for this development and has an important responsibility to reverse it". China has not confirmed its support for tougher sanctions. [[University of Tokyo]] professor Tadashi Kimiya told Reuters: "Sanctions have already been imposed on almost everything possible, so the policy is at an impasse. In reality, the means by which the United States, South Korea and Japan can put pressure on North Korea have reached their limits".
U.S. President [[Barack Obama]], South Korean president [[Park Geun-hye]] and Japanese prime minister [[Shinzō Abe]] agreed to jointly "take additional significant steps, including new sanctions, to demonstrate to North Korea that there are consequences to its unlawful and dangerous actions". The U.S., South Korea and Japan immediately called an emergency closed-door meeting of the [[United Nations Security Council]]; in a statement issued on September 9, the Council strongly condemning the test and said that it would take "further significant measures" in response, as it had pledged to do in a previous resolution if a violation occurred again. The statement said that non-military actions such as sanctions would be taken under Article 41 of the [[United Nations Charter]].
