SHOCKING pictures have emerged apparently showing a North Korean military base that has "collapsed and fallen into the sea".

The base is in the same region where 200 workers are rumoured to have died following an implosion at nuclear test site last year.

Political activist Jacob Bogle, who has previously mapped the state, claims the photos show signs of a “large collapse and debris” at the coordinates 41.89599°, 129.94985°.

Mr Bogle tweeted: “There was a small collapse that happened around Jan/Feb 2015, and then the big one happened sometime after then but before Sept 2016.

“I surmise the large one happened as a result of trying to correct problems associated w/ the smaller one, but have no evidence for that.”

North Hamgyong Province is where the reclusive regime's nuclear testing facility is located.

Last October it was reported that 200 people had been killed in a collapse at the Punggye-ri test site shortly after the communist country executed their biggest ever nuclear test.

The news comes just days after satellite images showed increased tunnelling beneath the site.

The underground base, which is carved into a mountain in the north-east of the hermit kingdom, has been the site of North Korea's last five nuclear tests.

The images also show increased activity at the south of the site, which could also indicate that another nuke test is imminent.

“Throughout December 2017, mining carts and personnel were consistently present around the West Portal and there was significant expansion of the spoil pile,” reports 38 North.

The report continues: “On December 28, there were also a large number of personnel (100 to 200) observed in seven different formations whose purpose is unknown in the Southern Support Area.

“These activities underscore North Korea’s continued efforts to maintain the Punggye-ri site’s potential for future nuclear testing.”
