North Korea Resumes Work at Nuclear Test Site, Analysts Say

SEOUL, South Korea — North Korea has resumed work at its underground nuclear testing site, defense analysts said, as the country vowed to keep expanding its nuclear arsenal despite the latest United Nations sanctions.


The defense analysts also said that the North’s Sept. 3 nuclear test, which Pyongyang said was of a hydrogen bomb, may have been much more powerful than previously estimated.


In its first official reaction to the sanctions resolution adopted by the United Nations Security Council on Tuesday, North Korea’s Foreign Ministry said on Wednesday that the sanctions would only strengthen the country’s resolve to pursue its nuclear weapons program “at a faster pace without the slightest diversion.”


The sanctions resolution, adopted in response to the nuclear test this month, was the ninth passed by the Security Council since North Korea’s first such test in 2006. If enforced, it would deprive North Korea of 30 percent of its annual fuel imports. It also bans imports of textiles from North Korea, stripping the country of another key source of hard currency.


But the North, already heavily sanctioned, remained defiant on Wednesday, saying that it would “redouble the efforts to increase its strength to safeguard the country’s sovereignty and right to existence” and establish “practical equilibrium with the U.S.”


The statement, released through the North’s state media, came at about the same time that a group of defense analysts, after studying recent satellite images, said they had detected new vehicles, mining carts and other signs of activity at the Punggye-ri underground nuclear test site in northeast North Korea.


”Such activity, coming shortly after the largest underground nuclear test conducted at Punggye-ri to date (via the North Portal), suggests that on-site work could now be changing focus to further prepare those other portals for future underground nuclear testing,” the defense analysts, Frank V. Pabian, Joseph S. Bermudez Jr. and Jack Liu, said in a Tuesday report on 38 North, a website focused on North Korea. The analysts gave no indication that a test appeared to be imminent.

“这些活动出现在丰溪里核试验场(通过北出入口)进行了迄今为止最大的地下核试验不久之后,这表明,现场工作可能的重点可能发生了改变,为使用那些其他出入口进行未来地下核试验作进一步的准备工作,”国防分析师弗兰克·V·帕比安(Frank V. Pabian)、小约瑟夫·S·贝穆德斯(Joseph S. Bermudez Jr.)和杰克·刘(Jack Liu)周二在专门关注朝鲜的网站“三八线北”(38 North)发布的报告中写道。这些分析师没有给出会即将发生核试验的可能。

The analysts also said that the explosive yield from the Sept. 3 nuclear test may have been as much as 250 kilotons, based on revised estimates of the magnitude of the tremor created by the blast. That would be much higher than most official estimates, which have varied. Japan, for example, gave an estimate of 160 kilotons, while South Korea’s was as low as 50 kilotons.


The analysts said the data appeared to verify the North’s claim that it had detonated a hydrogen bomb, a much more powerful device than the atomic bombs it detonated in its early tests. The United States, South Korea and other governments have yet to confirm that the North tested such a weapon, but the Sept. 3 test, the North’s sixth, was by far its most powerful to date. Satellite imagery since the test has showed evidence of numerous landslides at the test site.


On Wednesday, South Korea’s Nuclear Safety and Security Commission said it had detected traces of radioactive xenon gas from the nuclear test. But the data was not sufficient to determine what type of nuclear device the North had detonated, it said.


The latest United Nations sanctions against the North were considerably weaker than what the United States had sought. Among other things, the Trump administration wanted a complete cutoff of oil exports to the North.


“We think it’s just another very small step — not a big deal,” President Trump said of the new sanctions on Tuesday. “But those sanctions are nothing compared to what ultimately will have to happen.”


In the past week, Mexico and Peru have decided to expel North Korean ambassadors to protest the country’s continued violation of United Nations sanctions. South Korea’s foreign minister, Kang Kyung-wha, said Tuesday that a Middle Eastern country, which she did not identify, had also agreed to expel Pyongyang’s envoy.


North Korea’s ambassador to Peru, Kim Hak-chol, said Tuesday that his expulsion “throws gasoline on the fire,” according to Reuters.

据路透社报道,朝鲜驻秘鲁大使金学哲(Kim Hak-chol)周二说,驱逐他是“火上浇油”。

On Wednesday, the South Korean military said it had successfully tested a new air-to-land “bunker buster” Taurus cruise missile, part of its effort to increase its ability to destroy key weapons sites and bunkers deep underground where the North’s leaders might take refuge.


South Korea has agreed to buy 260 Taurus missiles from Taurus Systems, a German and Swedish joint venture. The missiles are among billions of dollars’ worth of new weapons that South Korea is buying to strengthen its pre-emptive and retaliatory strike capabilities as a deterrent against North Korea.

作为花数十亿美元购买新武器的一部分,韩国已同意从德国和瑞典合资企业“金牛座”系统(Taurus Systems)购买260枚“金牛座”导弹。为威慑朝鲜,韩国正在加强自己先发制人和进行报复性打击的能力。

They have a maximum range of 310 miles, meaning that South Korean planes can launch them without entering North Korean airspace. They can also fly a low, terrain-hugging route to better avoid radar, defense officials said.


North Korea flew an intermediate-range missile over northern Japan last month and has threatened to launch more missiles into the Pacific.
