North Korea shut down its Punggye-ri nuclear test site on 23 May (Thursday) to demonstrate its commitment to denuclearization before the Trump-Kim summit.
The South Korean government welcomed the DPRK's unilateral nuclear concession to help facilitate a broader agreement with the United States to completely end its nuclear weapons program.

Punggye-ri Nuclear Test Site (Korean풍계리 핵 실험장; Hanja豊溪里核實驗場) was the only known nuclear test site of North Korea. Nuclear tests were conducted at the site in October 2006, May 2009, February 2013, January 2016, September 2016, and September 2017.[4]

Location of Nuclear tunnel portals in Punggye-ri[3]


The site has three visible tunnel entrances.[5] Based on satellite imagery, its exact location is 41°16′47.87″N 129°5′10.51″E / 41.2799639°N 129.0862528°E / 41.2799639; 129.0862528 in mountainous terrain in Kilju County, North Hamgyong Province. It is 2 km (1.2 mi) south of Mantapsan, 2 km (1.2 mi) west of Hwasong concentration camp and 12 km (7.5 mi) northwest of the Punggye-ri village. The most proximate settlement to the possible nuclear underground test site is Chik-tong, a small populated place located at 41°16′00″N 129°06′00″E / 41.26667°N 129.10000°E / 41.26667; 129.10000.[6] Sungjibaegam is a settlement located 24 kilometres (15 mi) from the tremor of the 2013 test.[7] Punggye-ri railway station is located at 41°07′51″N 129°09′49″E / 41.130833°N 129.163611°E / 41.130833; 129.163611.[8]


In January 2013, Google Maps was updated to include various locations in North Korea.[9] On 8 April 2013, it was reported that South Korea had observed activity at Punggye-ri, suggesting that a fourth nuclear test was being prepared, but the next test did not occur until January 2016.[10][11]

On 6 January 2016, North Korean state media announced a fourth nuclear test had been carried out successfully at the location using a hydrogen bomb.[12] Satellite imagery captured for monitoring website 38 North between January and April 2017 suggested that a sixth nuclear test was being prepared at the site, which was detonated on 3 September 2017.[13]

According to sources, people from the Punggye-ri nuclear test site have been banned from entering Pyongyang since the test due to the possibility of being radioactively contaminated.[14] According to the report of defectors, about 80% of trees died and all of the underground wells dried up in the site after the sixth nuclear test.[15]

On 3 and 23 September 2017, earthquakes which seem to be collapses of tunnels were detected with magnitude of 4.1 and 3.6 respectively.[16][2] A 17 October 2017 study published by the US-Korea Institute at Johns Hopkins University suggested the most recent test had caused "substantial damage to the existing tunnel network under Mount Mantap".[17][18]

On 30 October 2017, in testimony before the South Korean parliament, the director of South Korea's Meteorological Administration warned that "further tests at Punggye-ri could cause the mountain to collapse and release radioactivity into the environment."[18] Likewise, Chinese scientists warned that if the mountain collapsed, nuclear fallout could spread across "an entire hemisphere."[18]

On 1 November 2017 Japanese TV station TV Asahi reported that according to unconfirmed reports, several tunnels collapsed at the test site on 10 October 2017.[19] An initial collapse was said to have killed 100 workers, with another 100 rescuers killed in a second collapse.[20][21]

On 20 April 2018 the North Korean government announced that it would suspend nuclear tests and shut down the Punggye-ri nuclear test site.[22]

On 14 May 2018 it was reported that commercial satellite imagery indicated that dismantling of the facilities at the test site had begun.[23] The leader and Supreme Commander of North Korea Kim Jong-un determined the date for the closing ceremony of Punggye-ri - 23-25 May 2018. The government of North Korea allowed a handful of international journalists (but none from South Korea) to observe the closing ceremony. Notably absent would be experts or inspectors who could study the test site at close quarters.[24]

On 24 May 2018 foreign journalists reported that tunnels in the Punggye-ri nuclear test site had been destroyed by the North Korean government in a move to reduce regional tensions.[25]

International ObservationEdit

On 31 October 2018, Kim Min-ki, a lawmaker in South Korea's ruling Democratic Party, stated that now defunct Punggye-ri was among other nuclear and missile test sites which had been observed by officials from South Korea's National Intelligence Service and that it was now ready for planned international inspection.[26]
