Scientists Say N. Korea's Nuclear Test Site Likely Collapsed

科學(xué)家稱(chēng)朝鮮核試驗(yàn)場(chǎng)可能已坍塌

Chinese researchers say the mountain above North Korea's main nuclear test site has likely collapsed. If so, the collapse would make the test site unsafe for future testing, and the area would need to be examined for any leaking radiation.

中國(guó)研究人員表示，朝鮮主要核試驗(yàn)場(chǎng)上方的山脈可能已經(jīng)崩塌。如果是這樣，這種崩塌會(huì)使得核試驗(yàn)場(chǎng)對(duì)未來(lái)的核試驗(yàn)來(lái)說(shuō)不安全，該地區(qū)還需要檢查是否存在任何輻射泄露。

Scientists at the University of Science and Technology of China carried out the research. Their findings may give new meaning to North Korean President Kim Jong Un's recent announcement. He said this month that his country was ending its nuclear testing program ahead of planned meetings with the leaders of South Korea and the United States.

中國(guó)科學(xué)技術(shù)大學(xué)的科學(xué)家們進(jìn)行了這項(xiàng)研究。他們的研究結(jié)果給朝鮮總統(tǒng)金正恩最近的聲明賦予了新的意義。金正恩本月表示，朝鮮將在會(huì)見(jiàn)韓、美領(lǐng)導(dǎo)人之前終止該國(guó)的核試驗(yàn)項(xiàng)目。

The results also support findings of an earlier study by a group of Chinese researchers. That report was published in March by the journal Geophysical Research Letters.

這一結(jié)果也支持了一群中國(guó)研究人員先前研究的結(jié)果。那份報(bào)告于3月份發(fā)表在《地球物理研究快報(bào)》上。

The latest study has also been accepted for publication by Geophysical Research Letters.

這項(xiàng)最近研究也已經(jīng)被《地球物理研究快報(bào)》接收準(zhǔn)備發(fā)表。

What could have happened?

可能發(fā)生了什么?

The data in the most recent Chinese study was collected following the most powerful of North Korea's six nuclear device tests, on September 3. That test was at least 10 times stronger than anything the country had tested before. Scientists say the explosion may have helped cause four earthquakes in the following weeks. Earthquakes do not naturally happen in the area around the test site.

中國(guó)這項(xiàng)最新研究中的數(shù)據(jù)是在9月3日朝鮮最強(qiáng)烈的第六次核試驗(yàn)之后收集到的。這次核試驗(yàn)的強(qiáng)度比該國(guó)此前進(jìn)行的任何試驗(yàn)都要強(qiáng)至少10倍以上。科學(xué)家表示，這次爆炸可能助長(zhǎng)了接下來(lái)幾周發(fā)生的四次地震。該試驗(yàn)場(chǎng)附近地區(qū)的地震并非自然發(fā)生。

The report by University of Science and Technology researchers said the first of those earthquakes was "an onsite collapse toward the nuclear test center." They urged officials to continue to watch for leaks of radioactive material.

中科大研究人員的報(bào)告稱(chēng)，其中第一次地震是朝著核試驗(yàn)中心的現(xiàn)場(chǎng)坍塌。他們督促有關(guān)官員繼續(xù)關(guān)注放射性物質(zhì)的泄露。

Special concern to China

中國(guó)特別關(guān)注

North Korea's nuclear tests are of special concern to China; the test site is less than 100 kilometers from the China-North Korea border.

中國(guó)特別關(guān)注朝鮮的核試驗(yàn)。該試驗(yàn)場(chǎng)距離中超邊境不到100公里。

North Korean nuclear tests have caused seismic events in Chinese border towns and cities. The explosions have led to evacuations of schools and offices, and fears of wind-carried radiation.

朝鮮核試驗(yàn)已經(jīng)造成中國(guó)邊境城鎮(zhèn)發(fā)生數(shù)次地震。這些爆炸還導(dǎo)致學(xué)校和辦公室疏散，以及對(duì)大風(fēng)吹來(lái)輻射的擔(dān)心。

Chinese officials have said they have not measured any radiation risk from recent samples collected along the China-North Korea border.

中國(guó)官員表示，他們沒(méi)有測(cè)到中朝邊境沿線(xiàn)近期采集樣本的輻射風(fēng)險(xiǎn)。

Relations between China and North Korea have been worsening. Last month, North Korean President Kim Jong Un made a visit to Beijing, after Chinese officials put United Nations economic sanctions against the North in place. The sanctions reduced trade between the two countries by as much as 90 percent.

中朝兩國(guó)之間的關(guān)系一直在惡化。上月，朝鮮總統(tǒng)金正恩在中國(guó)官員落實(shí)聯(lián)合國(guó)對(duì)朝經(jīng)濟(jì)制裁之后訪(fǎng)問(wèn)了北京。制裁使得兩國(guó)之間的貿(mào)易減少了多達(dá)90%。

On Saturday, North Korea announced it would close its nuclear testing site and suspend nuclear and intercontinental ballistic missile tests. U.S. President Donald Trump called the moves "big progress."

周六，朝鮮宣布將會(huì)關(guān)閉其核試驗(yàn)場(chǎng)，并暫停核試驗(yàn)和洲際導(dǎo)彈試驗(yàn)。美國(guó)總統(tǒng)川普稱(chēng)這些舉動(dòng)是“重大進(jìn)展。”

However, the North did not say whether it would give up its nuclear weapons or limit its production of missiles and their related parts.

然而，朝鮮并未說(shuō)明是否會(huì)放棄核武器或限制其導(dǎo)彈及相關(guān)部件的生產(chǎn)。

Chinese researchers say the mountain above North Korea’s main nuclear test site has likely collapsed. If so, the collapse would make the test site unsafe for future testing, and the area would need to be examined for any leaking radiation.

Special concern to China

North Korea’s nuclear tests are of special concern to China; the test site is less than 100 kilometers from the China-North Korea border.

North Korean nuclear tests have caused seismic events in Chinese border towns and cities. The explosions have led to evacuations of schools and offices, and fears of wind-carried radiation.

Chinese officials have said they have not measured any radiation risk from recent samples collected along the China-North Korea border.

Relations between China and North Korea have been worsening. Last month, North Korean President Kim Jong Un made a visit to Beijing, after Chinese officials put United Nations economic sanctions against the North in place. The sanctions reduced trade between the two countries by as much as 90 percent.

On Saturday, North Korea announced it would close its nuclear testing site and suspend nuclear and intercontinental ballistic missile tests. U.S. President Donald Trump called the moves “big progress.”
