Nuclear leaks at North Korean test site ARE a radiological mess

Nuclear Leaks At Nth Korean Test Site – real or “a Furphy” according to Broinowski ? Real, says Langley 

I have been following the story of radiological dangers posed by the increasing stressed geology of the North Korean nuclear test site for some months. Over the last week the story was again raised by the Australian newspaper. This motivated me to find the closest Chinese authority. The story was, as far as I can gather, published this week in The South China Morning Post on Wednesday 25 April 2018. The article, written by Stephen Chen, is entitled “North Korea’s nuclear test site has collapsed … and that may be why Kim Jong-un suspended tests“. The first paragraph explains further: “The mountain’s collapse after a fifth blast last fall has led to the creation of a massive ‘chimney’ that could leak radioactive fallout into the air, researchers have found….” before I go any further, there are two questions to ask: 1. How credible is Stephen Chen’s reporting and 2. Who are the researchers involved? eg are they retired diplomats only or are they qualified to comment in a scientific manner? If so have their findings been peered reviewed?

(what journalists say is irrelevant to me except when the articles lead me to find the peer reviewed papers published by scientists. Newspapers seem not to put relevant links to source documents up which is a crying shame.)

1. Stephen Chen: his bio on the SCMP site states: “Stephen covers breakthoughs in science and their impact on society, environment, military, geopolitics, business – pretty much all aspects of life. His stories often travel across the globe. Stephen is an alumnus of Shantou University, the Hong Kong University of Science and Technology, and the Semester at Sea programme which he attended with a full scholarship from the Seawise Foundation. In his spare time, Stephen reads and writes novels. He lives in Beijing with a beautiful wife and two lovely kids.”

fair enough, signs look hopeful that the article is not reporting a scientific “furphy”, as Broinowski described the generic story on the Australian ABC TV this morning. But let’s dig a nanometer deeper. Who are the researchers Chen is referencing? Does he name them and are they famous? (fame = mass readership and lots of grant money):

“A research team led by Wen Lianxing, a geologist with the University of Science and Technology of China in Hefei, concluded that the collapse occurred following the detonation last autumn of North Korea’s most powerful thermal nuclear warhead in a tunnel about 700 metres (2,296 feet) below the mountain’s peak.

The test turned the mountain into fragile fragments, the researchers found….” end quote from the SCMP/Chen.

Further, Chen reports: “A research team led by Wen Lianxing, a geologist with the University of Science and Technology of China in Hefei, concluded that the collapse occurred following the detonation last autumn of North Korea’s most powerful thermal nuclear warhead in a tunnel about 700 metres (2,296 feet) below the mountain’s peak.

The test turned the mountain into fragile fragments, the researchers found. ” source: ibid.

Describing these findings and the dangers posed by the scientific observations as reported by Chen does not smack of “Furphy” or fantasy Richard B. (No I don’t mind who your sister is, you should know better).

Wen Lianxing et al have been tracking North Korean nuclear tests, as far as I can find (hamstrung as I am, because I cannot speak or read Chinese), from at least 2006, and certainly since 2009, when the team became the first in the world to precisely locate the location of a North Korean nuclear test. : “High-precision Location of North Korea’s 2009 Nuclear Test”
Article in Seismological Research Letters 81(1):26-29 · January 2010 authors: Lianxing Wen, University of Science and Technology of China (Hefei, China); Hui Long, Stony Brook University (Stony Brook, United States).

Have a read of it Mr Broinowski. You might find it sensible and not a furphy.

Ok, on with the real matters at hand. Underground nuke tests invariably leak radionuclides into the biosphere. The US underground nuclear test regime has created a legacy of cost and risk, to put it mildly, which continues to this day. Name a US underground shot, and go to DOE Opennet and enter the shot’s code name. Up pops reams of documents detailing the test, the immediate result, and the long term consequences in terms of risk and costs.

There is no reason to suspect that the risks and costs of North Korea’s underground will be any more “furphy” ridden that the US underground tests were. And continue to be.

So without any further ado, even if I have to drag Richard B kicking and screaming into 1954, is some more non furphy from Chen and the SCMP:

“It is necessary to continue monitoring possible leaks of radioactive materials caused by the collapse incident,” Wen’s team said in the statement.

The findings will be published on the website of the peer-reviewed journal, Geophysical Research Letters, likely next month.

North Korea saw the mountain as an ideal location for underground nuclear experiments because of its elevation – it stood more than 2,100 metres (6,888 feet) above sea level – and its terrain of thick, gentle slopes that seemed capable of resisting structural damage…..

“The mountain’s surface had shown no visible damage after four underground nuclear tests before 2017.

But the 100-kilotonne bomb that went off on September 3 vaporised surrounding rocks with unprecedented heat and opened a space that was up to 200 metres (656 feet) in diameter, according to a statement posted on the Wen team’s website on Monday. ….

“As shock waves tore through and loosened more rocks, a large section of the mountain’s ridge, less than half a kilometre (0.3 mile) from the peak, slipped down into the empty pocket created by the blast, leaving a scar visible in satellite images.

Wen concluded that the mountain had collapsed after analysing data collected from nearly 2,000 seismic stations. ….

“Three small earthquakes that hit nearby regions in the wake of the collapse added credence to his conclusion, suggesting the test site had lost its geological stability.

Another research team led by Liu Junqing at the Jilin Earthquake Agency with the China Earthquake Administration in Changchun reached similar conclusions to the Wen team. ….

“The “rock collapse … was for the first time documented in North Korea’s test site,” Liu’s team wrote in a paper published last month in Geophysical Research Letters.

The breakdown not only took off part of the mountain’s summit but also created a “chimney” that could allow fallout to rise from the blast centre into the air, they said. …

“Zhao Lianfeng, a researcher with the Institute of Earth Science at the Chinese Academy of Sciences in Beijing, said the two studies supported a consensus among scientists that “the site was wrecked” beyond repair.

“Their findings are in agreement to our observations,” he said.

“Different teams using different data have come up with similar conclusions,” Zhao said. “The only difference was in some technical details. This is the best guess that can be made by the world outside.” ….

“Speculation grew that North Korea’s site was in trouble when Lee Doh-sik, the top North Korean geologist, visited Zhao’s institute about two weeks after the test and met privately with senior Chinese government geologists.

“Although the purpose of Lee’s visit was not disclosed, two days later Pyongyang announced it would no longer conduct land-based nuclear tests.”

” Hu Xingdou, a Beijing-based scholar who follows North Korea’s nuclear programme, said it was highly likely that Pyongyang had received a stark warning from Beijing.

““The test was not only destabilising the site but increasing the risk of eruption of the Changbai Mountain,” a large, active volcano at China-Korean border, said Hu, who asked that his university affiliation not be disclosed for this article because of the topic’s sensitivity.

“The mountain’s collapse has likely dealt a huge blow to North Korea’s nuclear programme, Hu said.

Hit by crippling international economic sanctions over its nuclear ambitions, the country might lack sufficient resources to soon resume testing at a new site, he said.

“But there are other sites suitable for testing,” Hu said. “They must be closely monitored.”

Guo Qiuju, a Peking University professor who has belonged to a panel that has advised the Chinese government on emergency responses to radioactive hazards, said that if fallout escaped through cracks, it could be carried by wind over the Chinese border.

“So far we have not detected an abnormal increase of radioactivity levels,” Guo said. “But we will continue to monitor the surrounding region with a large [amount] of highly sensitive equipment and analyse the data in state-of-the-art laboratories.”

“Zhao Guodong, a government nuclear waste confinement specialist at the University of South China, said that the North Korean government should allow scientists from China and other countries to enter the test site and evaluate the damage.

“We can put a thick layer of soil on top of the collapsed site, fill the cracks with special cement, or remove the pollutants with chemical solution,” he said.

“There are many methods to deal with the problem. All they need [to do] is ask.” end quote . source: ibid.

For the sake of ignorant ex diplomats everywhere, let me list all the qualified scientists Chen gives as sources for his article:

1. Wen Lianxing
2. Liu Junqing
3. Zhao Lianfeng
4. Hu Xingdou
5. Guo Qiuju
6. Zhao Guodong

The above qualified people consider that North Korean nuclear tests have, and do, pose a continuing radiological risk to North Korea and to China. This is due to the geologic damage the test series have caused. As any rational person with knowledge of the US underground test era knows, such risks are extremely well documented in the case of the US tests and appalling documented in the case of North Korea.

Dissenters from my point view and the content of Chen’s reported based upon his 6 expert sources are: 1. Richard Broinowski, retired diplomat. Not a scientist.

blows rasberry at RD. so sue me.

P.S. and another thing Richard B. You won’t close the South Korean nuclear plants down by going on TV and denying the North Korean radiological mess, which is probably an undisclosed actual disaster for the people there. Underground nuke test sites have many ways of leaking radionuclides. Over the years a test site’s hydrology is main vector, but anything can happen at the time, and, in the US experience has happened. The chances of uncontained radionuclides let loose into the biosphere is very high in North Korea and no ideology can successfully hide that fact. Your comments on the ABC TV this morning were damaging to the movement and frankly, in my opinion, bloody ignorant. Would you accept the facts of the matter if the scientists Chen cites were all born in London and were named “Watt”?

This post has been posted on Mr Stephen Chen’s facebook page. with thanks to him and his sources.

North Korea still able to test nuclear weapons – test site was not destroyed

No, North Korea’s Nuclear Test Site Wasn’t Destroyed in an Earthquake, National Interest, David Axe, 27 Apr 18, 

While it’s hard to know for sure what’s really going on in North Korea, one of the most secretive countries in the world, Pyongyang’s underground nuclear test facilities are probably intact, and the regime is likely still capable of testing its rudimentary atomic warhead designs.

Major media outlets reported on April 25, 2018 that large portions of North Korea’s underground nuclear test facility had collapsed and were unusable.

 The stories in The Wall Street Journal and other newspapers and websites, all citing a Chinese study first obtained by the Hong Kong-based South China Morning Post, are potentially misleading. News reports aggregating The Wall Street Journal’s own, more balanced reporting draw a line between the apparent collapse and upcoming talks between the United States and North and South Korea, but some experts are doubtful.

While it’s hard to know for sure what’s really going on in North Korea, one of the most secretive countries in the world, Pyongyang’s underground nuclear test facilities are probably intact, and the regime is likely still capable of testing its rudimentary atomic warhead designs. “The reporting has been mostly hot garbage,” Jeffrey Lewis, a nuclear expert at the Middlebury Institute of International Studies at Monterey, tweeted after reviewing satellite imagery of the 7,200-foot Mount Mantap, where North Korea’s Punggye-ri test site is located. …….

Mount Mantap didn’t collapse. Yes, seismologists registered a 6.3-magnitude earthquake under the mountain on September 3, the result of North Korea’s sixth and most recent underground atomic test. And yes, it’s possible that the quake collapsed the subterranean cavity that the buried bomb blast produced. ……


“Nuclear explosions make cavities,” Lewis explained in a tweet. “One of those cavities collapsed, which seismologists detected. Science is cool. But a cavity collapse does not mean the tunnel complex collapsed, let alone the whole mountain.”

Even if a cavity or part of the adjacent facility was destroyed, there’s no reason North Korean leader Kim Jong Un can’t simply build a new site. “Kim can dig new tunnels quickly to replace the collapsed sites if he chooses to do so,” Bruce Blair, a Princeton University nuclear expert, told me. “He could even test above ground if deemed warranted. There is really nothing technical standing in the way.”

……… Experts agree that North Korea hopes to leverage its newfound nuclear-power status for political or economic gain.  Suspending testing is a good-faith gesture and bargaining ploy that yields what Kim wants out of his testing program politically,” Blair said.   

    “Kim has agreed to stop nuclear testing because of the summit(s), not because his nuclear test mountain collapsed,” Lewis added. http://nationalinterest.org/blog/the-buzz/no-north-koreas-nuclear-test-site-wasnt-destroyed-earthquake-25587

Was the collapsed nuclear test site Kim Jong Un’s REAL reason for suspending nuclear tests?

That’s One Reason To Suspend Nuclear Tests: North Korea’s Most Recent Blast Collapsed a Mountain http://fortune.com/2018/04/25/north-korea-nuclear-test-mountain-mount-mantap/,By DAVID MEYER .April 25, 2018

Last weekend, North Korea suspended its nuclear tests and shut down the site where the last six detonations took place: underneath Mount Mantap, in the country’s northeast.

The reasons are ostensibly diplomatic, pointing to a thaw in relations between Kim Jong-un’s regime and South Korea and the West, but some noted that Pyongyang might have also been worried that the mountain was at risk of collapsing, as it visibly shifted during the last nuclear test. However, two separate groups of Chinese scientists now say Mount Mantap did in fact collapse after that detonation.

That means there’s a risk of radioactive contamination spreading not only within North Korea, but to other countries in the region. The site is not far from North Korea’s borders with China and Russia.

According to geologists from the University of Science and Technology of China, the collapse took place minutes after Kim Jong-un’s regime conducted its last nuclear test in September of last year.

The test of the 100-kiloton bomb, which led Chinese seismologists to register a 6.3 magnitude earthquake, apparently opened up a hole of up to 656 feet in diameter. Part of the mountain then fell into the hole.

The findings of the team, led by renowned seismologist Wen Lianxing, are set to be published next month in the journal Geophysical Research Letters.

According to the Hong Kong-based South China Morning Post, another team from the China Earthquake Administration reckons the collapse created a “chimney” that could allow the escape of fallout. The publication quoted researcher Zhao Lianfeng from the Chinese Academy of Sciences as saying the site was “wrecked” beyond repair.

So Pyongyang’s renouncement of land-based nuclear tests, for now, appears to be motivated by more than mere diplomatic concerns.

Report from China that North Korea’s “nuclear mountain” test site has collapsed

 

North Korea radiation WARNING as shock report deems nuclear test site UNUSABLE https://www.express.co.uk/news/world/951489/north-korea-news-kim-jong-un-nuclear-test-site-punggye-ri-radiation

NORTH Korea’s main nuclear test site has collapsed after multiple explosions and could be vulnerable to radiation leaks, according to a team of Chinese geologists.By SIMON OSBORNE

Scientists at the University of Science and Technology of China said the partial collapse of a mountain containing test tunnels, as well as the risk of radiation leaks, have potentially rendered the site unusable. Their study was published soon after Kim said his country would stop testing nuclear weapons and ballistic missiles and close down Punggye-ri before his meeting with Moon.

The Chinese scientists collected data after the most powerful of the North’s six nuclear tests last September.

The controlled explosion, which caused a magnitude 6.3 tremor, is believed to have triggered four more earthquakes over the following weeks.

The study found there was “a near-vertical on-site collapse towards the nuclear test centre” about eight minutes after the test.

The report said: “In view of the research finding that the North Korea nuclear test site at Mount Mantap has collapsed, it is necessary to continue to monitor any leakage of radioactive materials that may have been caused by the collapse.”

North Korean nuclear tests have caused seismic events in Chinese border towns and cities, forcing evacuations of schools and offices, sparking fears of wind-borne radiation and leading to a backlash among some Chinese against their country’s unpredictable traditional ally.

On Saturday, Kim announced North Korea would close its nuclear testing facility and suspend nuclear and intercontinental ballistic missile tests – a move welcomed by US president Donald Trump as “big progress” – and which comes ahead of a planned summit between the leaders in late May or early June.

But Kim stopped short of promising to give up his nuclear weapons, and the missile test ban does not include shorter-range weapons capable of reaching Japan and South Korea.

Satellite photos indicate unusual activity at North Korea’s Punggye-ri nuclear test site

North Korea’s Punggye-ri Nuclear Test Site: Unusual Activity Observed , BY: 38 NORTH, APRIL 24, 2018  , analysis by Frank V. Pabian, Joseph S. Bermudez Jr. and Jack Liu  (EXCELLENT SATELLITE PHOTOS) 

On April 21, 2018 the state-run Korean Central News Agency (KCNA), quoted North Korean leader Kim Jong Un as saying, “under the proven condition of complete nuclear weapons, we no longer need any nuclear tests, mid-range and intercontinental ballistic rocket tests, and that the nuclear test site in northern area has also completed its mission.” Commercial satellite imagery of the Punggye-ri Nuclear Test Site from April 20, the day before the site’s closure was announced, shows some unusual activity. Most notably, approximately one dozen mining carts—at least eight connected in a long train—could be observed in an unusual arrangement on the spoil pile in the area closest to the West Portal. It is too early to conclude whether this display is related to Kim Jong Un’s announcement………

Conclusion

The appearance of a significant number of mining carts parked out on the West Portal’s spoil pile is unusual and its purpose remains unknown. Given Kim Jong Un’s announcement, it may be the first visible indication that North Korea intends to cease further tunneling at the Punggye-ri Nuclear Test Site. Such an assessment is purely speculative at this point, requiring additional imagery and analysis over the coming days and weeks to determine if this is indeed the case, and whether or not the Punggye-ri nuclear site is actually being closed down. https://www.38north.org/2018/04/punggye042418/

Hotline set up between North and South Korea

North and South Korea set up first hotline between leaders ahead of summit  , ABC News 21 Apr 18 
North and South Korea have installed the first telephone hotline between their leaders as they prepare for a rare summit next week aimed at resolving the nuclear standoff with Pyongyang.

Key points:
Kim Jong-un and Moon Jae-in will make their first call before next week’s summit
Their meeting will be only the third since the end of the Korean War in 1953
Kim Jong-un could also meet Donald Trump in May or June

South Korea’s presidential office said a successful test call was conducted on the hotline between Seoul’s presidential Blue House and Pyongyang’s powerful State Affairs Commission.

South Korean President Moon Jae-in and North Korean leader Kim Jong-un plan to make their first telephone conversation sometime before their face-to-face meeting next Friday at the border truce village of Panmunjom.

Too early to celebrate?

Donald Trump and Kim Jong-un have agreed to meet — but what’s the significance of the meeting and is it too early to have a sigh of relief?

South Korean officials say the hotline, which will be maintained after the summit, will help facilitate dialogue and reduce misunderstanding during times of tension………http://www.abc.net.au/news/2018-04-20/koreas-set-up-first-hotline-between-leaders-ahead-of-summit/9682364

North Korea just promised a huge concession on its nuclear weapons. It’s done that before. 

South Korean President Moon Jae-in said North Korea might end its nuclear program while the US keeps its troops in South Korea. We’ve been here before. Vox By Alex Wardalex.ward@vox.com  

North Korea may have just announced a major concession ahead of talks with President Donald Trump.

According to South Korean President Moon Jae-in on Thursday, North Korea is ready for “complete denuclearization,” meaning that it would stop improving its nuclear weapons and missiles that can hit America and its allies. What’s more, North Korea would do that — and the US can keep its troops in South Korea.

If North Korea is seriously considering that, it would be a marked shift from its past stance. When Pyongyang usually talks about denuclearization, US troop removal is always a sticking point. Pyongyang fears that US troops are only waiting to invade North Korea, and so it wants to keep its nuclear arsenal to deter that incursion. But now, it’s possible America’s 28,500 troops on the Korean Peninsula can stay as North Korea winds down its program.

Pyongyang’s new stance, if true, could change the tenor of Trump’s potential meeting with North Korean leader Kim Jong Un in late May or early June. Abraham Denmark, a former top Asia security official at the Pentagon, tweeted on Thursday that North Korea’s announcement could mean Trump and Kim may strike an agreement.

“Looks like a deal may actually be coming together,” Denmark said. “Shaping up to be a comprehensive package that involves a peace regime, denuclearization, and eventual normalization of relations.”

Donald Trump to demand “full denuclearisation” of North Korea, in exchange for US embassy in Pyongyang’

Donald Trump ‘to tell Kim Jong-un to scrap nuclear arsenal within year in return for US embassy in Pyongyang’ ,  Julian Ryall, Tokyo, Nicola Smith, Telegraph UK Taipei 

President Donald Trump is expected to demand that Pyongyang abolish its nuclear weapons capability within a year when he sits down for talks with Kim Jong-un, the North Korean dictator, but will offer to open an embassy in the North’s capital and provide humanitarian assistance as an incentive.

The details offer a sense of the rapid pace of progress towards talks although analysts suggest the timetable may be overambitious.

Quoting sources in Washington, South Korea’s Chosun Ilbo newspaper said Mr Trump rejected Pyongyang’s proposals for “phased and synchronised” steps to eliminate the North’s nuclear arsenal and will instead insist that full denuclearisation is completed within 12 months of their meeting. …….https://www.telegraph.co.uk/news/2018/04/13/donald-trump-tell-kim-jong-un-scrap-nuclear-arsenal-within-year/

Kim Jong-un will not give up North Korea’s nuclear weapons

 https://www.brookings.edu/blog/order-from-chaos/2018/04/09/kim-jong-un-will-not-give-up-north-koreas-nuclear-weapons/ Evans J.R. Revere, Monday, April 9, 2018  

Editor’s Note:If President Trump insists on meeting Kim Jong-un, he must be prepared either to agree to a long negotiating process that will play into Kim’s hands, or to walk away from the table, writes Evans Revers. Faced with these options, the prudent choice might be to press the “pause” button. This piece originally appeared on Newsweek.

President Donald J. Trump’s upcoming summit with North Korean leader Kim Jong-un will be an historic encounter between two supremely self-confident, headstrong, and mercurial men, each seeking the other’s surrender.

The irresistible force of Donald Trump, whose administration has declared it will never accept, allow, or tolerate a North Korean nuclear threat to America, will soon meet the immovable object of a North Korean regime that has declared it will never give up its nuclear weapons “even in a dream.” What could possibly go wrong?

President Trump agreed to the summit on a whim, surprising his advisers and the South Korean envoys who conveyed Kim Jong-un’s invitation. Had he discussed the invitation with his advisers first, he would have heard that Kim’s reported interest in a deal on “denuclearization of the whole Korean Peninsula” is nothing of the kind.

Those who have negotiated nuclear matters with Pyongyang know that Kim’s words were a familiar North Korean demand to end the “threat” posed by the U.S.-South Korea alliance, the presence of U.S. troops in Korea, and the nuclear umbrella that defends South Korea and Japan.

A senior North Korean official once explained to a group of American experts, “If you remove those threats, we will feel more secure and in ten or twenty years’ time we may be able to consider denuclearization. In the meantime,” he continued, “we are prepared to meet with you as one nuclear weapon state with another to discuss arms control.”

That is North Korea’s concept of “denuclearization.” It bears no resemblance to the American definition.

Through “back channels”, secret talks go on between USA and North Korea

Secret, direct talks underway between US and North Korea, By Elise Labott, Kevin Liptak and Jenna McLaughlin, CNN, April 7, 2018  Washington  The United States and North Korea have been holding secret, direct talks to prepare for a summit between President Donald Trump and North Korea leader Kim Jong Un, a sign that planning for the highly anticipated meeting is progressing, several administration officials familiar with the discussions tell CNN.

Central Intelligence Agency Director Mike Pompeo and a team at the CIA have been working through intelligence back-channels to make preparations for the summit, the officials said. American and North Korean intelligence officials have spoken several times and have even met in a third country, with a focus on nailing down a location for the talks.
Although the North Korean regime has not publicly declared its invitation by Kim Jong Un to meet with Trump, which was conveyed last month by a South Korean envoy, several officials say North Korea has since acknowledged Trump’s acceptance, and Pyongyang has reaffirmed Kim is willing to discuss the denuclearization of the Korean peninsula……..https://edition.cnn.com/2018/04/07/politics/north-korea-us-talks/index.html

Japanese Foreign Minister’s Reports of Tunneling at Punggye-ri:  not supported by Commercial Satellite Imagery 

Japanese Foreign Minister’s Reports of Tunneling at Punggye-ri: What Commercial Satellite Imagery Shows  [excellent photos] BY: 38 NORTH, APRIL 2, 2018A  Analysis by Frank V. Pabian, Joseph S. Bermudez Jr., and Jack Liu.

On March 31, 2018, Japan’s Foreign Minister, Taro Kono, in a lecture in Kochi city, is reported to have said that North Korea appears to be “working hard to get ready for the next nuclear test,” and the associated reporting claims that he had added that soil had been “removed from the tunnel at the nuclear test site where past tests were conducted.” The reporting also suggested that his remarks “may be based on satellite imagery provided by the United States.”

While it is unclear whether the Foreign Minister was referring to activity observed over the last few days or from earlier work conducted after North Korea’s September 2017 nuclear test, commercial satellite imagery from March 23 shows quite a different picture: namely, that activity at the test site has been significantly reduced compared to previous months. Tunneling at the West Portal, a site not associated with any of North Korea’s previous tests, had been active earlier this year but has slowed down significantly as has other personnel and vehicular movement around the site. (It appears that only a small amount of new spoil has been excavated from the tunnel recently).[1]

Nevertheless, it is highly likely that the North Koreans continue to maintain the readiness of the nuclear test facility—one indication is recent roadwork—to allow nuclear testing in the future should Pyongyang decide to do so.

1. Precise determination of the extent of new spoil accumulation is made difficult from March 17 to 23 due to variations in the imagery deriving from different sensors on different satellites from different vendors having different look angles and slightly different amounts of melted snow together with vegetative shadowing.

Japan warns that North Korea is digging new tunnel, “preparing for nuclear test”

North Korea is ‘preparing for nuclear test by digging tunnel’   http://www.news.com.au/world/asia/north-korea-is-preparing-for-nuclear-test-by-digging-tunnel/news-story/69fe873a70328b72addac06b9924c3d2  JAPAN has warned that North Korea is “doing everything possible” to prepare for the next nuclear test by digging a new tunnel. 

NORTH Korea is gearing up for a new nuclear test by digging an underground tunnel, Japan has warned.

The country’s Foreign Minister Taro Kono said: “[North Korea] is doing everything possible to prepare for the next nuclear test: it is currently extracting earth from an underground tunnel where the previous test was carried out.”

The minister said previously the secretive state “does not reveal its intentions to the outside world in terms of denuclearisation”.

The claim comes just days after Kim Jong-un promised to bin his beloved nuclear weapons if he could be guaranteed security and US military threats against North Korea were to stop.

At the end of last year the tyrant declared his country a fully fledged nuclear power after launching a new missile he claimed was capable of hitting anywhere on the planet.

Nuclear devices are often tested underground to prevent radioactive material released in the explosion reaching the surface and contaminating the environment — this method also ensures a degree of secrecy.

The release of radiation from an underground nuclear explosion — an effect known as “venting” — would give away clues to the technical composition and size of a country’s device.

A test site is carefully geologically surveyed to ensure suitability — usually in a place well away from population centres.

The nuclear device is placed into a drilled hole or tunnel usually between 200-800m below the surface, and several metres wide. Last year a tunnel at an underground North Korean nuclear site was said to have collapsed.

Up to 200 people were thought to have died at the Punggye-ri nuclear test site in the northeast of the country.

The accident was believed to have been caused by Kim Jong-un’s sixth nuclear test which weakened the mountain, according to the report.

Former British Defence Secretary Sir Michael Fallon previously warned that Britain is at risk from North Korea’s long-range nuclear missile program as some cities are closer than American targets.

Revised estimates suggest the total number of missiles the rogue state has is believed to be between 13 and 21.

And the regime is estimated to have at least four nuclear warheads.

Satellite images of Jong-un’s main missile test site in August revealed North Korea’s weapons were more powerful than initially thought.

Careful analysis of North Korean tests sites, using images from Planet, reveal the regime has been gradually building up the size of its missiles.

Kim Jong Un’s complete turnaround in tactics: will it result in peace, or not?

But together, the Kim-Moon meeting serves more as a prelude to the Trump-Kim summit. And if those talks fail, Harry Kazianis, an Asia security expert at the Center for the National Interest think tank, thinks the chances of war might increase.

“We are putting all of our eggs in the summit basket,” he told me. “This is the ultimate Hail Mary.”

The North Korea nuclear standoff: how we went from “fire and fury” to talks in under a year Vox,  “North Korea has 100 percent changed its tactics.” By Alex Wardalex.ward@vox.com  

Last year, it seemed like war between the United States and North Korea was a real possibility.

“The United States has great strength and patience, but if it is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea,” President Donald Trumpsaid at the United Nations on September 19, 2017. “Rocket Man is on a suicide mission for himself and for his regime,” he continued, using his favored nickname for North Korean leader Kim Jong Un.

Flash-forward to March 29, 2018, when Pyongyang and Seoul announced that Kim and South Korean President Moon Jae-in will meet face to face in April for talks. It’ll be only the third in-person meeting between the heads of both countries, and the first since 2007. But that’s not all: The Kim-Moon summit will lay the groundwork for an even more historic meeting between Kim and Trump sometime in either May or June, although it remains unscheduled.

How did we get here? How did North Korea and the US go from talk of potential nuclear warto actual, well, talks? Here’s one explanation: Experts tell me the war threats may have actually scared leaders like Trump.

“I’d like to believe that while President Trump talks tough,” Leon Panetta, the former defense secretary and CIA director, told me, “deep down, he also is concerned about involving this country in another war that is going to cost thousands of lives.”

But others simply give credit to North Korea. “North Korea has 100 percent changed its tactics,” Sue Mi Terry, a North Korea expert at the Center for Strategic and International Studies think tank, told me. “I think this is all North Korea actually driving this.”

Whatever the reason, top officials want to take advantage of this moment. “We must not let this historic opportunity for diplomacy go to waste,” Sen. Ed Markey (D-MA), a member of the Senate Foreign Relations committee, told me.

What follows is a guide to how the two countries went from a nuclear standoff to a rare moment of cautious optimism.

Kim pivots from bombs to talks………..

The coming Trump-Kim summit made the South Korea meeting possible

On March 8, South Korean envoys who had just met with Kim Jong Un relayed a message to Trump: The North Korean leader wanted to meet with him. Trump reportedly accepted the offer on the spot.

The president even tweeted about his excitement.

Moon, the South Korean president, seemed relieved by the news. He campaigned in part on easing tensions with North Korea and continually advocated for a diplomatic solution to the US-North Korea standoff. After Trump agreed to meet with Kim, Moon offered three-way talks between him and the other two leaders.

That, however, is not in the works. Instead, Moon and Kim finally set a date for their face-to-face meeting in April. But Terry, the North Korea expert, told me she doesn’t expect much from the Kim-Moon summit. Instead, she said “South Korea’s chief goal is to set up that [the] Trump-Kim meeting goes well.”

As for Kim, he likely wants a greater sense of how badly Moon wants to strike some sort of deal.

Kim is already preparing for both encounters. This week, he took a secret trip to Beijing to meet with Chinese President Xi Jinping. Oriana Skylar Mastro, a China expert at Georgetown University, told me in an interview that Kim wanted to ensure he had China’s support ahead of talks with the US. Having Beijing’s backing could help Kim not concede too much in talks with Moon and Trump.

Kim needs the help. Trump will want Kim to give up his nuclear weapons, but experts are unanimous that Kim won’t agree to do so. Having China’s support allows the North Korean leader to feel more comfortable defying the American president.

“I think the North Korean leader made some very smart moves and has put himself in a good position,” Panetta, the former Obama Cabinet official, told me. “He has given himself greater leverage ahead of these meetings.”

Put together, the Kim-Moon meeting serves more as a prelude to the Trump-Kim summit. And if those talks fail, Harry Kazianis, an Asia security expert at the Center for the National Interest think tank, thinks the chances of war might increase.

“We are putting all of our eggs in the summit basket,” he told me. “This is the ultimate Hail Mary.” https://www.vox.com/2018/3/30/17176316/north-korea-south-trump-fire-fury-moon

Increased activity at North Korean nuclear site

Renewed activity at North Korean nuclear site sparks fears, UNNERVING satellite images of a North Korean nuclear site suggest that Kim Jong-un may be expanding his nuclear program. Eric Talmadge, news.com.au  APMARCH 29, 2018

INCREASED activity at a North Korean nuclear site has once again caught the attention of analysts and renewed concerns about the complexities of denuclearisation talks.

The satallite imagery, taken last month, were released as United States President Donald Trump prepares for a summit with Kim Jong-un in the coming weeks.

Yesterday, Xinhua News revealed that during a secret visit to China, Mr Kim had told Chinese President Xi Jinping that he was ready for talks with the US about nuclear weapons, promising to give up his nuclear arsenal.

But observers believe these images suggest the North has begun preliminary testing of an experimental light water reactor and possibly brought another reactor online at its Yongbyon Nuclear Research Centre.

Both could be used to produce the fissile materials needed for nuclear bombs.

The findings come at a particularly sensitive time.

Trump and Kim are planning to meet by May, according to officials, and denuclearisation will likely be the biggest topic on their agenda if they do meet………..http://www.news.com.au/world/asia/renewed-activity-at-north-korean-nuclear-site-sparks-fears/news-story/d0f03838c7d7460b5ccda2288975d54b
