North Korea’s Punggye-ri Nuclear Test Site: New Activity at the North Portal

By 38 North
28 March 2017

A 38 North exclusive with analysis by Joseph S. Bermudez and Jack Liu.

New commercial satellite imagery of the Punggye-ri Nuclear Test Site from March 25 shows the continued presence of three to four vehicles or equipment trailers at the entrance to the North Portal. The texture of the ground from the portal entrance past the vehicles or equipment trailers suggests that communications cables may have been laid on the ground. This equipment would likely be used to initiate the test, collect data from the explosion and process the data. Also notable, water is being pumped out of the portal and draining downhill to the east and west, presumably to keep the tunnel dry for monitoring or communications equipment.

Would one rod down the center work?

So they no longer do their analysis on dated images. They must be on a countdown, too.

We can only hope the explosion if 50 times more than they planned for.
