A study by Chinese geologists shows the mountain above North Korea’s main nuclear test site has collapsed under the stress of nuclear test explosions. This would render the site unsafe for further nuclear testing and necessitate monitoring for any leaking radiation.
Is this perhaps the reason Kim Jong-Un has agreed to denuclearize North Korea? Perhaps, but of course, we’ll probably never know. The findings by the scientists at the University of Science and Technology of China may shed new light on North Korean President Kim Jong Un’s announcement that his country was ceasing its testing program.
Nuclear explosions release enormous amounts of heat and energy, and the North’s largest test in September was believed early on to have rendered the site in northeastern North Korea unstable. The data in the latest Chinese study was collected following the most powerful of the North’s six nuclear device tests on September 3, 2017 that they believed could have triggered four earthquakes over the following weeks. The yield of the bomb was estimated at more than 100 kilotons of TNT, at least 10 times stronger than anything the North had tested previously. (The bomb the United States dropped on Hiroshima in 1945 had a yield of about 15 kilotons.)
The University of Science and Technology of China paper, authored by Tian Dongdong, Yao Jiawen, and Wen Lianxing, said the first of those earthquakes that occurred eight-and-a-half minutes after the explosion was “an onsite collapse toward the nuclear test center,” while those that followed were an “earthquake swarm” in similar locations.
“In view of the research finding that the North Korea nuclear test site at Mantapsan has collapsed, it is necessary to continue to monitor any leakage of radioactive materials that may have been caused by the collapse,” the authors said in a summary dated Monday and viewed Wednesday on the university’s website. –USA Today
The Chinese study makes sense and is based on “well-understood research,” said Rowena Lohman, a seismologist at Cornell University who wasn’t part of the work, but believes there’s an international effort that monitors these tests for radiation. The study is peer-reviewed and has been accepted for publication by the journal Geophysical Research Letters.
On Saturday, North Korea announced it will close its nuclear testing facility and suspend nuclear and intercontinental ballistic missile tests (a move welcomed by President Trump as “big progress”) and which comes ahead of a planned summit between Trump and Kim.
However, the media wants us all to know that the North stopped short of suggesting it will give up its nuclear weapons or scale back its production of missiles and their related components.
