‘Artificial earthquake’ strikes North Korea near known nuclear test site
An earthquake measuring 6.3 magnitude has struck North Korea near a known nuclear test site, Punggye-ri, suggesting that Pyongyang may have conducted its sixth nuclear test, Yonhap reports.
An allegedly artificial quake was detected at 12:36pm in North Hamgyeong Province, according to the Korea Meteorological Administration (KMA), Yonhap reports.
"Today, at around 12:36pm, we detected an artificial earthquake measuring 5.6 magnitude... we are analyzing whether a nuclear test was conducted," South Korea's Joint Chiefs of Staff said, according to Yonhap.
The USGS reported the tremor as a 6.3 magnitude, while China's earthquake administration also said it detected a 6.3 magnitude earthquake in northeastern North Korea, calling it a "suspected explosion," Reuters reported.
The Pentagon and the JCS have urgently called for a crisis countermeasure, assuming that North Korea is most likely to have conducted a sixth nuclear test, the report added. Seoul has placed its military on highest alert and is closely cooperating with the US.
Seoul's presidential office has already accused its neighbor of conducting a nuclear test while president Moon Jae-in has convened a National Security Council meeting.
Earlier in the day, North Korea's official news agency (KCNA) reported that the Nuclear Weapons Institute has created a “more developed nuke,” that can be fitted on an intercontinental ballistic missile (ICBM).
The new alleged hydrogen bomb, the report said, not only features “enormous destructive power” but can also be used to detonate a “super powerful”electromagnetic pulse.
South Korea’s National Intelligence Service warned Monday that its neighbor might be preparing its sixth nuclear weapon test from a nuclear test site in Punggye-ri. North Korea has already conducted five nuclear tests – in 2006, 2009, 2013 and in January and September 2016. During the last test, the North claimed it had successfully detonated a small nuclear warhead.

The earthquake struck 75 km (45 miles) north northwest of Kimchaek. Previous recent tremors in the region have been caused by nuclear tests, which if the case this time round, is bound to increase the tension hours after U.S. President Donald Trump and Japanese Prime Minister Shinzo Abe talked by phone about the “escalating” nuclear crisis.
The quake was only 10 km deep, the U.S. Geological Survey said, again suggesting a nuclear device.
Witnesses in the Chinese city of Yanji, on the border with North Korea, said they felt a tremor that lasted roughly 10 seconds, followed by an aftershock.
The hydrogen bomb report by North Korea’s official KCNA news agency comes amid heightened regional tension following Pyongyang’s two tests of intercontinental ballistic missiles (ICBM) in July that potentially could fly about 10,000 km (6,200 miles), putting many parts of the mainland United States within range.
Under third-generation leader Kim Jong Un, North Korea has been pursuing a nuclear device small and light enough to fit on a long-range ballistic missile, without affecting its range and making it capable of surviving re-entry into the Earth’s atmosphere.
North Korea, which carries out its nuclear and missile programmes in defiance of UN Security Council resolutions and sanctions, “recently succeeded” in making a more advanced hydrogen bomb that will be loaded on to an ICBM, KCNA said.
“The H-bomb, the explosive power of which is adjustable from tens kiloton to hundreds kiloton, is a multi-functional thermonuclear nuke with great destructive power which can be detonated even at high altitudes for super-powerful EMP (electromagnetic pulse) attack according to strategic goals,” KCNA said.
“All components of the H-bomb were homemade and all the processes ... were put on the Juche basis, thus enabling the country to produce powerful nuclear weapons as many as it wants,” KCNA quoted Kim as saying.
Juche is North Korea’s homegrown ideology of self-reliance that is a mix of Marxism and extreme nationalism preached by state founder Kim Il Sung, the current leader’s grandfather. It says its weapons programmes are needed to counter U.S. aggression.
North Korea offered no evidence for its latest claim, and Kim Dong-yub, a military expert at Kyungnam University’s Institute of Far Eastern Studies in Seoul, was sceptical.
“Referring to tens to hundreds of kilotons, it doesn’t appear to be talking about a fully fledged H-bomb. It’s more likely a boosted nuclear device,” Kim said, referring to an atomic bomb which uses some hydrogen isotopes to boost explosive yield.
A hydrogen bomb can achieve thousands of kilotons of explosive yield - massively more powerful than some 10 to 15 kilotons that North Korea’s last nuclear test in September was estimated to have produced, similar to the bomb dropped on Hiroshima, Japan, in 1945.
Kim Jong Un, who visited the country’s nuclear weapons institute, “watched an H-bomb to be loaded into new ICBM” and “set forth tasks to be fulfilled in the research into nukes,” KCNA said.
Pictures released by the agency showed Kim inspecting a silver-coloured, hourglass-shaped warhead in the visit accompanied by nuclear scientists, with a concept diagram of its Hwasong-14 long-range ballistic missile seen hanging on the wall.
The shape shows a marked difference from pictures of the ball-shaped device North Korea released in March last year, and appears to indicate the appearance of a two-stage thermonuclear weapon, or a hydrogen bomb, said Lee Choon-geun, senior research fellow at state-run Science and Technology Policy Institute.
“The pictures show a more complete form of a possible hydrogen bomb, with a primary fission bomb and a secondary fusion stage connected together in an hourglass shape,” Lee said.
Tensions on the Korean peninsula have been high since last month when North Korea threatened to launch missiles into the sea near the strategically located U.S. Pacific territory of Guam after Trump said Pyongyang would face “fire and fury” if it threatened the United States.
North Korea further raised regional tensions on Tuesday by launching an intermediate-range ballistic missile over Japan, drawing international condemnation.
Trump and Abe spoke by phone and said that in face of an “escalating” situation with North Korea that close cooperation between their countries and with South Korea was needed, Abe told reporters.
Trump told Abe that the United States, as an ally, was 100 percent with Japan, Deputy Chief Cabinet Secretary Yasutoshi Nishimura told reporters.
“The two leaders reaffirmed the importance of close cooperation between the United States, Japan and South Korea in the face of the growing threat from North Korea,” the White House said in a statement. “President Trump noted that he looks forward to continued trilateral coordination on the margins of the United Nations General Assembly.”
The United States has repeatedly urged China, the North’s sole major ally, to do more to rein in its neighbour.
North Korea last year conducted its fourth and fifth nuclear tests, saying the fourth in January 2016 was a successful hydrogen bomb test, although outside experts say the claim has not been proved.
Impoverished North Korea and the rich, democratic South are technically still at war because their 1950-53 conflict ended in a truce, not a peace treaty. The North regularly threatens to destroy the South and its main ally, the United States.
