The original article from Science:
The rise, collapse, and compaction of Mt. Mantap from the 3 September 2017 North Korean nuclear test
Abstract
Surveillance of clandestine nuclear tests relies on a global seismic network, but the potential of spaceborne monitoring has been underexploited. Here, we determined the complete surface displacement field of up to 3.5 m of divergent horizontal motion with 0.5 m of subsidence associated with North Koreas largest underground nuclear test using satellite radar imagery. Combining insight from geodetic and seismological remote sensing, we found that the aftermath of the initial explosive deformation involved subsidence associated with sub-surface collapse and aseismic compaction of the damaged rocks of the test site. The explosive yield from the nuclear detonation with seismic modeling for 450m depth was between 120-304 kt of TNT equivalent. Our results demonstrate the capability of spaceborne remote sensing to help characterize large underground nuclear tests.
Fig. 4 Summary deformation scenario for the 3 September 2017 North Koreas Nuclear test. The unfolding of events includes the succession of (A) explosive, (B) collapse, and (D) compaction processes, with different associated surface displacements. The implosive source (C) may be shallow and only contribute localized surface displacements. The radar imagery reveals the deformation (arrows in (D)] resulting from the three processes.

And a quick look at a map will show you why China is extremely ticked over it.

Numerous rocket launch failures and the big implosion. Trump told the Chicoms...stop him NOW.

“... the mountains interior might have changed after a hydrogen bomb test...”
Gee, ya think? I guess they didn’t use enough 2x4s to shore it up.

It’s about 80 miles from the Chinese border.
Close enough for radioactivity to waft over if the mountain opened up.

That was a Jerry Pournelle idea from the 1950s. RIP Jerry, such a modern Renaissance Man. A true conservative. One of the few people I respected who was strongly against going into Iraq post-9/11. He was right.

I was reading several variations of how these scientists etc. are looking at it......some saying it’s worse than they thought. At any rate it’s a pile of radio active dust and dirt! So Kim saying he would close this site is really he wants someone else to clean up the mess he left it in!

Pretty much sums it up. Norks made a big mess. China told them to fix it. Norks dont know how or the money to fix it. Here we are. Guess who will pay to clean this up.

I suspect Kims busy cleaning up bodies around the place...he doesn’t care if it kills the people doing it.

This news could create panic among rocket and nuclear scientists in N. Korea. They would probably not mind being shipped to U.S.. First, Kim will try to disperse them among civilian population, turning them into farmers and car mechanic for example. However, it is also possible that Kim Jong-un may decide to liquidate(kill) them in order to clean up evidence and keep their mouth shut.

Northeast China (traditionally called Manchuria), the area adjacent to the Korean Peninsula, is a mining and heavy manufacturing region of China with a population over 100 million. Yeah, they’re not happy with Fat Boy’s hobby.

The guy in Blue in the back is the lead nuclear guy I understand......Also I understand after Russia fell apart some of their guys were sent to N.Korea to instruct them further on nuclear.....course that's been a great while now

On the other hand, it would be nearly impossible to destroy all records on their nuke and ICBM program. In this day and age, you only need hundreds of external hard drives who can easily fit into a large suitcase. It is easy to disperse them hide somewhere. Even a roomful of such hard drives can be hidden that way.
