The US Geological Survey said the epicentre of the quake was in the northeast of the country, some 50 kilometres (30 miles) northwest of Kilju city, placing it right next to the Punggye-ri nuclear test site.

N.Korea Digging New Nuclear Test Tunnel North Korea is digging a new tunnel at nuclear test site in remote North Hamgyong Province, satellite pictures appear to show. "Imagery from October and November 2015 show an additional structure and what appear to be significant tailings, indicating excavation of a new tunnel is underway," the website 38 North at Johns Hopkins University said Wednesday. The new tunnel lies to the northwest of the nuclear test site and is connected to nearby Mt. Musan. There are two older tunnels where the North conducted its nuclear tests in 2006, 2009 and 2013 and one...

Korea conducted small nuclear test in 2010: China professor A Chinese professor has claimed that North Korea conducted a "low-yield underground nuclear test" in May 2010, possibly backing a claim by North Korea that it succeeded in carrying out a nuclear fusion reaction at that time. Wen Lianxing, the professor who leads a research group on earthquakes and physics at the Beijing-based University of Science and Technology of China, said the North's claimed nuclear test yielded a 2.9-ton blast with a margin of error of 0.8 ton. The claimed nuclear test...

Yonhap News Agency December 21, 2013 1:16pm N. Korea unlikely to conduct nuclear test for several months WASHINGTON, Dec. 20 (Yonhap) -- North Korea is not likely to conduct another nuclear test anytime soon, a U.S. institute said Friday, citing recent satellite images that showed ongoing construction work at the only known nuclear test site in the reclusive country. The assessment by 38 North, a website by the U.S. Korea Institute of Johns Hopkins University, comes as recent satellite images showed construction work underway to build new a tunnel at the nuclear test site that can be used to detonate...

N. Korea ready for 4th nuclear test, yet no imminent sign: Seoul 2013/11/15 13:58 By Kim Eun-jung SEOUL, Nov. 15 (Yonhap) -- North Korea is ready to conduct another nuclear test, but no imminent sign has been detected at its main site in the northeastern tip, South Korea's defense ministry said Friday.

The southern tunnel...

The Justice Department did more than seize a Fox News reporter's emails while suggesting he was a criminal "co-conspirator" in a leak case -- it did so under one of the most serious wartime laws in America, the Espionage Act. It's the same law used by the Nixon administration to go after The New York Times and Daniel Ellsberg over the leak of the Pentagon Papers. It's the law used to charge the Rosenbergs, American communists, for allegedly passing secret information to the Soviet Union -- they were executed for the offense in 1953. One Washington attorney, who represents two...

China: North Korea Could Carry Out Fourth Nuclear Test William Ide April 22, 2013 BEIJING — A top military official in China says it is possible North Korea could carry out a fourth nuclear test.

U.S. intelligence has detected the departure from a North Korean port of a North Korean ship suspected of carrying military equipment banned under a U.N. sanctions resolution against Pyongyang's Oct. 9 nuclear test, CBS News reported Thursday. The United States is tracking the ship, CBS said, noting that it remains uncertain exactly what the ship is carrying and where it is headed.

In 1946, the United States conducted a series of nuclear weapon tests at Bikini Atoll in what’s known as Operation Crossroads. A total of two bombs were detonated to test the effects nuclear blasts had on naval warships. The second, named Baker, was the world’s first nuke to be detonated underwater. Due to the unique properties of underwater explosions, the Baker test produced a number of unique photographs that the world had never seen before.

Exclusive: North Korea tells China of preparations for fresh nuclear test By Benjamin Kang Lim BEIJING | Fri Feb 15, 2013 8:31am EST (Reuters) - North Korea has told its key ally, China, that it is prepared to stage one or even two more nuclear tests this year in an effort to force the United States into diplomatic talks with Pyongyang, said a source with direct knowledge of the message.

SEOUL (Reuters) - North Korea conducted a nuclear test on Tuesday, South Korea's defence ministry said, after seismic activity measuring 4.9 magnitude was registered by the U.S. Geological Survey. The epicentre of the seismic activity, which was only one km below the Earth's surface, was close to the North's known nuclear test site. "We've been informed by the South Koreans that there's been a (North Korean) nuclear test," a U.N. Security Council diplomat told Reuters on condition of anonymity. An international nuclear test monitoring agency said the location of the seismic event was "roughly congruent with" 2006 and 2008 tests...

2013/02/10 14:08 KST N. Korea says world mistakenly interprets its "important measures" as nuclear test SEOUL, Feb. 10 (Yonhap) -- North Korea's planned important measures may not refer to a third nuclear test, a state propaganda outlet has suggested, adding to the confusion over Pyongyang's nuclear ambitions. "The U.S. and hostile forces jumped to conclusions that the republic is planning the third nuclear test, citing their hypothesis and argument," the propaganda weekly Tongil Sinbo said Friday in an article posted on a Web site operated by the North. The weekly said the U.S. and other countries know little about what...

Kim attended a meeting of the National...

Is N.Korea Planning 2 Nuke Tests? North Korea has virtually finished preparations for nuclear tests in two tunnels at the Punggye-ri nuclear test site in North Hamgyong Province, observers believe. A South Korean government source said analysis of satellite images showed brisk activity of support vehicles and personnel at a tunnel on the southern side of the test site, and on Saturday the area was cleaned and personnel left. Intelligence agencies suspect that this means a nuclear test is imminent. Preparations at a tunnel on the western side of the site were apparently completed earlier. The government here is now...

North Disguising Test Site Activities By Mok Yong Jae [2013-02-01 21:07 ] North Korea has installed a screen over the entrance to one of the test tunnels at its nuclear test site in Kilju County, North Hamkyung Province, inhibiting intelligence gathering activities and raising fears of an impending nuclear detonation. A government source explained today, “It is believed that a roof-shaped obstruction has been installed. It appears to be a measure to stop leaks of information on preparations for a nuclear test, which are currently in their final stages.” A second source went on, “It is one way for North...

N.Korea 'Poised to Conduct Nuclear Test' North Korea appears to have completed preparations for a nuclear test with the installation of measuring equipment near the entrance of an underground test site in Pungye-ri, North Hamgyong Province, a senior government official here said Thursday.
